We're a company doing real operational work in e-commerce/3PL logistics. AI usage internally is still basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows in production yet. That's what this role is for. You'd be the first dedicated AI engineer here. Two things at once: ship agentic workflows that replace real manual work, and build the underlying platform (APIs, MCP tools, docs) so other teams can build their own instead of asking you for everything forever. First project: an agent that reads an inbound invoice question, pulls the correct (often complex) invoice, and drafts a context-aware reply a teammate can review and send. Currently ~1 hour of manual work, target is ~30 seconds. What we need:
3+ years SWE, 1-2+ of which building production AI systems (not prototypes) 10+ agentic/LLM workflows shipped end-to-end — not toy demos Evidence you've built infra/tools for other people to use, not just yourself Strong Python and/or TypeScript Some background in e-commerce, 3PL, logistics, or comparable B2B ops
Nice to have: RAG, vector DBs, multi-step orchestration, eval frameworks, heavy Cursor/Claude Code/Copilot usage. Fully remote, direct access to leadership, real scope to define how AI gets built here rather than inheriting someone else's stack.

Proton builds the privacy-first alternative to Big Tech: Mail, VPN, Drive, Pass, Calendar, and Lumo AI. We're profitable, have no VC control, and are majority owned by the nonprofit Proton Foundation, so no one can force a change in mission.
The Drive Foundation team builds the core SDK powering every Proton Drive client,C#, TypeScript, and Rust daily, with Swift and Kotlin bindings for mobile. It's foundational work: what you build here ships to every Drive client, and there's a crypto model revamp plus a Rust based next gen SDK on the roadmap.
Looking for someone with 5+ years of professional software experience and strong Rust expertise (ownership, concurrency), plus experience building libraries for client applications (web/mobile/desktop). Don't check every box but think you'd be a strong fit? We say apply anyway.

Orbit is an AI-first logistics operating system — order intake, route planning, carrier management, driver app, tracking, documents — replacing the Excel-and-phone stack that most of transport logistics still runs on. We're bootstrapped, profitable, and growing in a market full of VC-funded competitors. Our customers stay because the product works.
The role: we call it Product Engineer because you own a piece of the product from idea to production — deciding the solution, building it, shipping it, iterating on feedback. Not ticket-driven work. Small, strong team.
How we build: spec-driven agentic development, not vibe coding. You orchestrate agents against structured specs and persistent project context, verify output, and help build the harness itself (skills, context layers, workflows, evals). We think the engineering bottleneck has moved from typing speed to judgment — knowing what good software looks like and directing agents to produce it. If that matches how you already work, you'll feel at home.
Stack: TypeScript everywhere, zod, tRPC, Node.js, AWS (Lambda, DynamoDB/ElectroDB, SST), React/Remix, React Native/Expo. AI layer via Bedrock. You don't need to know every line of it.
Culture: all-remote (EU), async-first, low-meeting. Writing is the most important skill here. Profit sharing via our "Own Orbit" program, quarterly meetups in Hamburg, team offsites ("SpaceWalks") wherever two or more Orbiters want to meet — Orbit covers the stay. Good English required; German is a plus (customers and product are German-speaking).
No cover letter. Show us something you built — a side project, an agent workflow, a repo, an MCP server — and tell us how you work with agents.
AI usage today is basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows yet. This is a founding seat to build that: shipping high-impact agentic workflows yourself, plus reusable building blocks (APIs, MCP tools, docs) so any team can build their own.
Example first project: an agent for inbound invoice questions — reads the question, pulls the right invoice, drafts a context-aware reply — turning an hour of manual work into ~30 seconds.
Need: 3+ yrs SWE with 1-2+ yrs shipping production AI systems, 10+ real agentic/LLM workflows built end-to-end, a genuine platform mindset (built tools/infra for others, not just yourself), strong Python and/or TypeScript, and relevant sector background (e-commerce, 3PL, logistics, or similar B2B).
Nice to have: RAG pipelines, vector DBs, multi-step agent orchestration, eval frameworks.

Rebuilding core marketplace flows (Search -> Booking -> Post-booking) and consolidating fragmented pricing/inventory logic into a clean backend domain. Senior, Staff-leaning: you own pricing/inventory/search, ship end-to-end (UI + API + data model + rollout), mentor engineers, report to Head of Eng. Clear growth path to Staff.
Stack: Next.js/React/TypeScript/Tailwind + Ruby on Rails/Node.js + Postgres/MongoDB + AWS/Datadog + Playwright.
Need: 4+ yrs production web apps, comfortable in both Rails and React, solid on schema design/query performance.
Bonus: international expansion (Mexico/Caribbean, then Europe) and new verticals (Spa) coming this year — good time to join if you like greenfield scope.

ResortPass is rebuilding the web experience behind one of the largest hospitality marketplaces. We're rewriting ~75% of resortpass.com this year, focusing on Core Web Vitals, SEO, performance, and developer experience.
Roadmap this year is aggressive: international expansion (Mexico/Caribbean, then Europe), moving search off Algolia in-house, a new Hotel SaaS product, Spa as a new business line. AI features (concierge chat, AI booking assistant) are also landing on this frontend, so there's exposure there too.
You'll help lead large frontend initiatives, define architecture, mentor engineers, and work closely with Product and Backend teams.
Tech: React 19, Next.js 16 (App Router), TypeScript, Tailwind, shadcn/ui, Playwright, Datadog, Node.js, Ruby on Rails, PostgreSQL, MongoDB, AWS.

We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards.
Role - Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning. - This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end. - You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step. Revenue is surging, we need judgement to help shape the product. - Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it. - You care deeply about user privacy and data security. We work on identity. Sloppiness here is not an option.
Stack & ways of working - .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD. - Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful. - We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks.
Comp & apply
- Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time.

If you're in a workable timezone and excited about identity infrastructure, I'd love to talk.

airCFO is an AI-powered accounting & finance services partner to 300+ startups (current/former clients include Anthropic, Replit, Harmonic), and we are building a platform to supercharge our service's capabilities. We're hiring a founding engineer to build the systems behind it: a retrieval/RAG context layer over all our tools, and the internal apps (TypeScript, Node, Python/FastAPI, React, Postgres, Claude + MCP) our teams use daily. We want someone senior who drives coding agents hard but refuses to lose the plot — clean architecture and a real mental model of the whole system. Production RAG/agents a plus, not a requirement. You'd report to a hands-on fractional CTO; small team, high autonomy.
Email me at yair [dot] aviner {at} aircfo.com with "HN - Founding Engineer" in the subject.
We’re building an AI platform for construction: offline-first mobile/web apps that automate jobsite workflows, understand documents and blueprints, and connect the field to the office.
Looking for a strong mobile engineer to own our React Native/Expo app for iOS + Android, plus parts of our TypeScript web app. Backend is Scala/Play + PostgreSQL.
You’ll build for real field conditions: no signal, gloves, sun glare, dusty tablets, large blueprints, high-res photos, and messy jobsite data.

I'm leading the Growth team, and we're working to build new, beautiful UI experiences on our long-loved services. Our stack is a Remix/Rails product and Astro/Sanity marketing site, both backed with modern design system foundation (what you might expect with Typescript, Tailwind, ShadCN, Tanstack, etc). I'm looking for a principal-level engineer with strong taste in front-end: someone who cares about UX and styling, takes accessibility and page weight seriously, builds strong validation / testing harnesses, and keeps a dependency tree sane instead of letting it metastasize.
The other part of this role is contributing to our agents and workflows. We've invested heavily here with the right mix of enthusiasm, guardrails, and budget. You'll have heavy influence over how it evolves: what we hand to agents vs. keep in human hands, how work gets specified and parallelized, how we keep the results beautiful, and where the security and review gates live. There’s a ton of opportunity to work with the latest AI tooling and determine best practices as the industry matures. We’re a small team happily working over 15 years with high impact, high autonomy, and low bureaucracy. Come join us! Apply at https://www.3playmedia.com/company/jobs-post/?gh_jid=7761973....

We’re looking to scale our engineering leadership team with technical leaders who want to raise the impact of a high-performing organization.
* Not Your Traditional "Jira-Manager": Our EMs are not classic delivery coordinators who shuffle meetings or build heavy processes. Instead, you will own people, hiring bar, technical judgment, and the health of our engineering systems.
* High-Autonomy Team: Because 80%+ of our engineering team is Senior–Staff+ level, our engineers already possess a high degree of ownership. Your focus is less on day-to-day task coordination and more on coaching independent owners, managing ambiguity, and raising team impact.
* Technically Credible Leaders: You will stay close enough to the work to challenge assumptions, review proposals, spot maintainability issues, and jump into the code to debug alongside engineers when needed.
* Organizational Advocates: Beyond your immediate team, you will act as an advocate owning the health and metrics of org-wide areas—ranging from CI/CD health and developer productivity to customer success collaboration and on-call sustainability.
* 100% Remote Async Culture: We maintain an even distribution of engineers across North America and Europe, optimizing for minimal process and maximum focus. * Here's how we're thinking about AI at Ashby:https://www.ashbyhq.com/blog/engineering/ai-ashby-engineerin...
* Full transparency on engineering levels + comp:https://www.ashbyhq.com/blog/engineering/leveling-and-compen...
Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis. (While you won't always be shipping code, you are expected to hold a deep technical understanding of the system).

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect race conditions.
A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll work with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

Hey HN, we’re ProxyBase. We’re building an API-first, fully headless SOCKS5 proxy network designed specifically for autonomous AI agents, LLM tool-calling, and large-scale web scraping.
Most traditional proxy networks operate in a bit of a gray area—they buy bandwidth harvested from sneaky, hidden SDK bundles embedded inside free apps. We're doing things differently:
100% Ethical Sourcing: We pay our node operators directly. People run our open-source CLI client to share their bandwidth and earn microcredits in real-time. It’s fully transparent, consent-driven, and compensated.
Built for Swarms, Not Dashboards: AI agents and automated workflows can provision, utilize, dynamically route (via metadata in the SOCKS5 auth string), and settle proxy fees entirely programmatically using US based stable coins without ever touching a manual web dashboard.
Our Tech Stack:
Backend: Rust (Actix-web, SQLite/DashMap, WebSockets, Yamux stream multiplexing) Frontend / Desktop: React, TypeScript, Tauri (our client-side bridge app)
What we're looking for:
Backend Engineer (Rust): Help us scale our high-concurrency SOCKS5-to-WebSocket relay gateway and real-time ledger settlement engines. Full-Stack Developer (TypeScript / Tauri / Rust): Own our local proxy bridging software, client-side developer portal, and integration libraries. If you like systems-level programming (TCP/UDP, tunnel multiplexing, concurrent state) and want to work on clean, developer-first infrastructure, we'd love to chat.
Drop us a line at
jobs@proxybase.xyz with a bit about what you've built.
We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds: we’re still coding. Notable recent projects include a gigantic ERP migration for Anduril Industries, and a skunkworks with Surge Labs helping to develop some of the frontier LLM models themselves (yes, seriously). This is a remote-first agency, but some projects involve onsite work.
I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership. Applicants must meet a high bar - I personally review every hire. In return you’ll get:
* Flexibility and a low-bureaucracy environment * Clients that won’t treat the vendor like “the B Team” * The chance to act as a code architect, not just implement tickets * Exposure to a wide variety of industries and modern challenges * Me as your personal champion and advocate Feel free to submit, even if you already did in the past.We’re currently especially seeking:
Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)
Tier 3 roles are typically 5-10 years experience with $150-$180K total comp.
Tier 4 roles are 11-20 years experience, $215-$260K total comp.
Higher tiers exist, and we always welcome exceptional applications.
Though not yet universal, many of our clients are now demanding senior/staff engineers with success using modern agentic approaches. Be ready to explain where current models work well and where they do not.

ViyaMD is building a physician-grade clinical intelligence platform for legal, insurance, and healthcare teams. We analyze large, messy medical record sets and turn them into clinically accurate timelines, reasoning, and insights in minutes.
We’re hiring for two senior roles:
# Staff Software Engineer: Own core product and platform systems: medical record ingestion, document understanding pipelines, backend/data infrastructure, clinical workflow, and production reliability.
We’re looking for:
* 5–8+ years of software engineering experience
* Strong Python/Typescript/backend engineering skills
* Experience with distributed systems, data-intensive apps, or large-scale document processing
* Ability to own ambiguous problems from architecture through production
* Interest in healthcare, clinical data, legal-tech, or AI products
# Staff ML Engineer: Own how ViyaMD evaluates and improves its clinical AI: define eval metrics, run model/agent evaluations, improve prompts and workflows, and close the loop through better retrieval, agentic systems, and fine-tuned models.
We’re looking for:
* 5–8+ years of professional experience
* Strong hands-on AI/ML evaluation experience
* Experience with LLMs, RAG, agents, fine-tuning, or applied ML systems
* Fluency in Python
* Healthcare or clinical experience is a strong plus, but not required
We’re especially excited about people who want to set the technical bar, work close to real users and data, and build AI systems that must be accurate and trusted in high-stakes domains.
You'd work directly with our founding team, with real influence over how we build. Comp: competitive salary, meaningful early-stage equity, and benefits. Email me at hari AT viyamd.com, if you're interested.
We secure the SaaS apps companies actually run on: M365, Salesforce, and hundreds more. You’d be on the Threat product team working full-stack. That means browser extension code (content/background scripts, manifest v3, message passing), backend services chewing through millions of events, and the data pipelines feeding our detection engine. One day you’re in TypeScript debugging why a content script won’t capture form submissions on some vendor’s weird SPA. The next you’re in Python fixing a Kafka consumer that’s falling behind. Sometimes you’re in Rust optimizing a hot path in the telemetry collector.
Big current focus is shadow AI, i.e. catching when employees paste sensitive data into ChatGPT, Claude, or whatever LLM showed up this week. You’d build the systems that detect it.
Looking for ~8+ yrs experience, real browser knowledge (DOM, event loop, SPA routing, CORS, not just “I used React”), prior browser extension work, strong TypeScript, comfortable in Python, willing to write Rust, plus data-at-scale chops (event streaming, Postgres, Elasticsearch, Kafka). Bonus: AI security (prompt injection, exfiltration), detection engineering/SIEM, or security tooling.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Hi HN! I'm Seema, Tech Recruiter at Ojin, and we're looking for a Product Engineer to join our small team.
We build the infrastructure that makes AI feel human — real-time AI agents with natural, lifelike conversation on a globally distributed GPU fabric. We've spent five years proving this works for enterprise customers and we're now opening it up as a developer platform — this is the team that will build it from the ground up.
You'd own features end-to-end: interactive frontends through to Python-based agentic backends, working directly with the founders on a 15 person team. You help define the solution, design the architecture and ship it.
Stack: TypeScript, React, Node.js, Python, WebRTC, WebSockets, AWS
Looking for: 3-5+ years, genuine full-stack ability, startup experience, and real enthusiasm for building AI products.
We're not able to offer relocation or visa sponsorship. If you're already in Berlin, this is a hybrid role. If you're elsewhere, we're open to fully remote within CET ±2h.
Apply or read more about us here: https://ojin.ai
Thank you!
We're working in the AI for science space, specifically at the point of experimental execution. Scientific labs run on expensive instruments locked behind proprietary software with no real API. Getting an agent to actually operate these machines is unsolved, and it's the bottleneck between "AI can design experiments" and "AI can run them." That's what we're building.
Small, technical, well-funded team with real design partners already pulling on us. You'd be one of the first engineers, working directly with the founders across the stack: agents, low-level systems, ML infra, and the runtime that ties it together. Lots of hard, unglamorous, high-leverage problems.
You might be a good fit if:
- You're a strong generalist who's shipped real systems and can go deep when needed
- You're comfortable in messy, low-level territory
- Bonus: ML/agents, scientific instrumentation, or industrial automation
- You want high ownership, high pace, onsite in NYC
We're mostly a Python/Rust/Typescript shop. We care about what you've built, not credentials.
To apply, email contact@tetherline.dev with a bit about yourself and something you've built you're proud of.

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model.
We've been building since 2020, started in campaign security and data science, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is an exciting opportunity for those who are interested in building systems and agents to solve hard and often adversarial problems.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). We’re looking for engineers with web scraping, data pipelines, or security tooling experience. Experience with Python/Django, Typescript, React, and LLM APIs is a plus. Must be authorized to work in the US.
Email steven@kanary.com with something you've built and why it was hard. Also be sure to include the keyword I’ve put in my HN profile.

To apply, email me directly at jlyman@axoventures.co with a short story about a favorite technical challenge you solved end-to-end. Please put "HN" in the subject line!
YC is hiring Product Engineers to build the future of YC -- and increasingly, software for startups everywhere.
We're a team of ~20 engineers building everything from Work at a Startup and Demo Day to investor software, founder tools, AI systems, and new open source projects. We don't have PMs. Engineers talk to users, decide what to build, and ship quickly.
Some of what we've been building:
* New products: GStack rethinks the software stack for an AI-native world. GBrain explores persistent memory and knowledge systems for AI. Paxel and other AI-powered products help founders—and increasingly everyone else -- build software and companies faster.
* Products at scale: We build and operate Work at a Startup (2M+ candidates, 1000s of early startups), Demo Day, our investor marketplace, SAFE signing, founder CRM, and the software that powers YC itself.
* Data: YC has over 20 years of proprietary startup data. We're applying it to how we think about the future of YC's batch, fundraising tools, hiring, recommendations, and entirely new ways to help people start and grow successful companies.
AI has fundamentally changed how we build software, and we're looking for engineers who are already experimenting with coding agents, MCP, LLMs, context engineering, evals, developer tooling, and whatever comes next. Our stack includes Rails, React, Postgres, Python, TypeScript, LLM APIs, and plenty of experimental infrastructure, but we're much more interested in great builders than expertise in any particular framework.
We're in person in San Francisco (Dogpatch). You'll work closely with founders and alongside people like Garry, Jared and Diana, helping define how YC—and startups more broadly—build software in the AI era.
We offer competitive compensation, carry in the YC fund, and a small, high-autonomy engineering team.
Learn more about the team and role at https://www.ycombinator.com/software. If this sounds exciting, I'd love to chat -- email me directly at ryan@ycombinator.com.
Distru is the #1 ERP in the cannabis industry, $3B in annual sales flows through our platform, and most of the top cannabis brands and distributors in the US run their entire operation on us to stay compliant.
We're profitable, stable, and growing — no runway anxiety, and we're reinvesting into new product lines. We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor).
Distru is at an inflection point. We have deep market penetration in cannabis ERP, a new commerce layer (Distru Commerce — a B2B wholesale marketplace) live and growing, and a roadmap with a growing AI component. Our live AI Order Agent already lets buyers submit orders in any format from any source, killing manual data entry, the first of many bets on using AI to strip the repetitive heavy lifting out of running an ERP.
The role: You'll own mission-critical, full-stack features end to end — planning, design, implementation, testing — across every part of the product. You might work on AI-native features (order/purchase intake, smart product matching, systems that learn from user feedback), Distru Commerce storefronts and ordering, manufacturing and distribution workflows, cultivation mobile tools for the floor, or compliance integrations with state systems like Metrc. It's a high-ownership role: you'll partner directly with product, design, support, and our C-suite, and you'll get customers writing you personal "thank you" emails.

Home-based care should be the default in American healthcare. It isn't, mostly because the technology has never been good enough. Patients heal faster at home, it costs a fraction of facility-based care, and it's what people actually want — yet the industry runs on phone calls, spreadsheets, and systems built in the 90s. We started Axle Health because we think that's fixable, and because the stakes are high enough that it's worth doing right.
We're Axle Health, and we think in-home care deserves world-class technology. We're building the operating system for home-based healthcare — the scheduling intelligence, the clinician tools, the logistics coordination — everything that has to work perfectly so a clinician shows up at the right door at the right time with everything they need. It's a hard and important problem, and we're just getting started.
The complexity is real: real-time scheduling optimization across dynamic clinician networks, last-mile logistics that make Uber Dispatch look simple, integrations with every flavor of EMR and payer system you've never heard of, mobile-first tools that have to work in spotty cell coverage in someone's living room, and the compliance surface area that comes with handling PHI at scale — we need to build it all, and we want people who think this stuff is genuinely fun.
Currently hiring Senior Software Engineers (7+ YOE) for:
Backend (Python + Django): https://www.axlehealth.com/careers?ashby_jid=8db08b55-399c-4...
Interoperability (Typescript + Node): https://www.axlehealth.com/careers?ashby_jid=0bcdc195-ac3f-4...

What’s exciting about this specific role & company right now? We partner with major health plans to make homes safer and more accessible for older adults and high-needs populations. By combining technology with a network of clinicians and installers, we deliver personalized home modifications nationwide. We’re fast-growing and backed by incredible investors like Valtruis and The Home Depot. As an engineer here, you’ll be solving complex data and scaling challenges that directly improve patient outcomes. We operate with high autonomy and a modern stack, giving you the room to ship meaningful code.

We’re a small UK-based free-to-play gaming company with a distributed EU team, growing fast after recent success and scaling our backend platform. We’re looking for two roles:
- mid-senior to senior engineer with at least 5+ years of experience. - Mid-senior devops engineer, minimum 5+ years of experience.
Backend: Strong in backend development, ideally Java, but open to those willing to learn. DevOps experience is a plus, or a strong desire to learn it.You’ll be expected to do devops as part of this role. Devops: Your main role will be devops on AWS. Willingness to learn Java. Expected to have familiarity with terraform, kubernetes, ec2, ALBs, route53, cloudflare.
Our stack includes Java, Python, TypeScript, Angular, SQL, AWS, Kubernetes, Postgres, Trino, Flux, Flagger, and Terraform.
Our engineers must be able to think product-first, and take a task from idea to production, work across the full cycle. You must write your own code, AI assistance is fine, but you must be able to produce all your work independently. No Cursor. We are looking for candidates that can write SQL when needed, our approach when it comes to the DB is SQL first. We also value clear thinking and communication, you should be comfortable sketching simple architecture or flow diagrams (boxes and lines, nothing formal) to explain your ideas.
To apply, please send an email to jack[at]splash.tech with the subject “Backend Hackernews 2026” or “Devops Hackernews 2026”. Please send any git/bitbucket/source-forge project that represents your coding otherwise I’ll ask you to complete a small test project.
When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.
We're a globally edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.
We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
- The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services.

Odin is the workforce visibility and compliance platform for critical infrastructure. We protect the world's largest construction projects, data centers, and critical assets, from groundbreak to post-turnover, unifying every layer of site security into a single command center: physical access control, workforce compliance, video monitoring, and drone surveillance. We're already on 500+ active projects with 100K+ workers on the platform, securing over $100B in construction value.
Our stack is TypeScript end to end, Node and GraphQL on the backend, React on web, React Native on mobile, Postgres and Kubernetes on GCP. We also integrate deeply with field hardware such as badge readers, kiosks, turnstiles, and cameras.
Lead Platform Engineer: end-to-end owner of the platform and hardware fleet everything runs on. Product teams are your customers. You own infra-as-code, CI/deploys/DX, monitoring, hardware fleet ops, and incident escalation.
Lead Software Engineer: technical owner of an autonomous 2-3 person product team, taking scoped projects from design through release. Not a people-management role.
Both: operational maturity, a habit of mentoring, and AI used to accelerate without outsourcing judgment. Jobsite-adjacent experience (construction tech, access control, IoT/hardware) is a bonus.

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We just recently announced our $42M Series B! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
We’re looking for product-minded, high ownership engineers to join our team! We’re hiring various mid-level, senior-level and staff-level engineers. Engineers own projects end-to-end so full stack ability is expected.
