Revieve builds AI-powered personalization for 120+ beauty brands across 40+ countries — think skin analysis, AR try-on, and recommendation engines used by some of the world's largest retailers. We're profitable, ~30 people, a dozen engineers, millions of end users.
We've reorganized around the idea that one builder with the right tools can do what teams used to. This role exists because we believe that's true.
What a week looks like: Mon — a real customer problem lands in front of you, full context, you decide what to build Tue — prototype in Claude Code, something running by EOD Wed — staging up, Loom to founders, iterate on notes Thu — in production, watching real data come in Fri — ship the next iteration or find the next problem
~1–2 hours of meetings per week. No standups. No sprints. No PM in the loop.
We're looking for: → Public proof of building — repos, side projects, real users. We click around it. → AI in production — not demos. Opinions on agents, evals, latency, what fails. → Agentic coding fluency — Claude Code, Codex, MCP, custom harnesses → TypeScript / React generalist — comfortable at any layer → Design taste — you know what's wrong with a screen without a designer telling you → Clear written thinking — READMEs, PRs, post-mortems
IMPORTANT: include a link to something you've built in your application.
Process: recruiter call → paid build session (real problem, you set the pace) → short presentation → done.
Perks: 5 weeks vacation from day one, remote-friendly, options plan, equipment budget, parental leave, competitive salary.

HelpMyCash is a Barcelona-based financial comparison platform. We're looking for a senior freelance DevOps/SRE to act as the operational safety net for a mature AWS production platform.
This is explicitly an insurance role: keep the platform reliable, no major evolution or greenfield work. The platform has run reliably for years (no critical outages unrelated to deploys/changes in 5+ years) — we want someone to keep it that way.
Engagement: ~4h/week retainer paid on-call for critical incidents planned/larger tasks quoted separately fully remote, EU/CET, reachable during Spanish business hours
Compensation: retainer + hourly rate + on-call premium for out-of-hours response. Exact structure and rates open to discussion based on your model.

We're operator-run, AI-native, and looking for our first AI Operations Lead to work directly with the co-founder to turn our AI capabilities into a serious operational advantage.
What you will do:
> Build the short-form engine: Design and run an AI-leveraged workflow to repurpose years of long-form content into 50-100 pieces/week for TikTok, Reels, and Shorts.
> Stand up owned analytics: Move us off spreadsheets and partner dashboards. Build clear tracking for email growth, content performance, and affiliate attribution.
> Be the AI execution engine: Build automations (Make, Zapier, n8n) and write Python or JavaScript when needed to glue systems together.
> Operationalize AI internally: Build practical AI workflows for our creative directors, salespeople, and content producers to speed up their output.
What we are looking for:
- You ship: You aren't just "AI-curious"—you use Claude, ChatGPT, and automation tools to do real work every week.
- You operate: You can take a directive like "we need a thing that does X" and come back with a finished system, making the small decisions along the way.
- You write: We work async. We use Slack, Notion, and Google Docs. If your default is to schedule a meeting, this is the wrong role.
Our culture: Async-first, zero bureaucracy, and a sustainable pace. We don't do crunch culture, we respect off-hours, and we completely pause work for Shabbat (Friday sundown to Saturday night). Sustained operators need sustained rest.

Brandfetch is the internet’s canonical source for logos and brand assets. Think GitHub for brand identity: a brand repo that auto-indexes public assets, lets brand owners “commit” changes once, then propagates them—instantly and immutably—through CDNs, plugins, and APIs used by companies like Google, Canva, Salesforce, and soon … everywhere.
Problems you'd work on:
- Nightly curation bot auto-fixing outdated assets across 52M+ repos
- Next-gen ingestion and partition-key schema to leap from millions to billions of assets
- MCP server that exposes structured brand data to any AI agent or LLM, letting them fetch brand context on demand
- Vector search: surface any logo with ≥90% similarity in <50ms
- Real-time metering that pings Stripe the instant a user tops their quota
Stack: Node.js, TypeScript, Python, AWS (Lambda, DynamoDB, CloudFront, S3, CloudFormation), Serverless.
You:
- 8+ years of experience in backend software development.
- Proficiency with AWS tools (Cloudformation, API Gateway, DynamoDB, Lambda, Cloudfront, S3, IAM, OpenSearch).
- Experience with building REST APIs.
- Ability to write well-documented, clean code.
- Experience with building DevOps pipelines using Serverless.
- Great communication skills (we work across multiple timezones and document everything).
- Experience with Machine Learning.
- Timezone: UTC+0 to UTC+9
Competitive salary + equity in a profitable, growing company.
apply: career at brandfetch.io (no recruiter please).
We run a worker wellbeing and compliance platform used by global buyers and their supply chain sites across Asia. We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years.
*The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head.
*What we're looking for:*
- Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it
*What this isn't:* This isn't a greenfield startup with infinite runway. It's a real product with real users, real technical debt, and a migration in progress. If that sounds like a problem, this role isn't for you. If that sounds like the most interesting kind of work, let's talk.

We power real-time Chat, Video, Activity Feeds, and AI Moderation for apps like Strava, Bumble, eBay, and Patreon - billions of API requests per month, millions of concurrent users.
We're looking for a hands-on Lead Engineer (Staff / Principal level) to own Platform & Infrastructure.
Reports directly to the CTO.
Small, senior team - you'll write code most of the time, not run a process org. First 6 months focus on three things with measurable outcomes:
* Cloud cost optimization (AWS/GCP) — tooling and guardrails, not reports
* Platform reliability and scalability — SLOs, observability, hardening
* Architecture decisions on Kubernetes, databases, and cloud provider strategy
Stack: Go, Python, AWS, GCP, Kubernetes, PostgreSQL, CockroachDB, Redis, Terraform.
Looking for: software engineering background (Go or Python, not scripting-only), production cloud cost optimization experience, real distributed systems depth, and active AI tooling use in your engineering workflow.
Not a fit if: you're security/compliance-heavy, scripting-only, or dependent on large-org support structures.

Hi, Alex and Jeremy here from UMH.
8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.
What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.
Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.
Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.
We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.
In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B. We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~500). Now we’re scaling the platform.
We have PMF, and it's time to scale! For more and to apply, see https://smarterdx.com/careers

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

I’m Kiran, Chief of Staff (CoS) at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
We are scaling up our AI training operations and looking to bring on a large number of contractors (up to 1,000 openings) to help evaluate, stress-test, and refine next-generation AI models.
The Role: Essentially, high-level RLHF (Reinforcement Learning from Human Feedback) and model evaluation. You will analyze AI-generated content across various domains, fact-check complex outputs, catch subtle hallucinations, and provide detailed, constructive feedback to improve model reasoning and accuracy. You'll also simulate real-world scenarios to gauge the model's actual utility.
What we are looking for:
Native-level English (C1/C2) is a hard requirement. Analytical Rigor: High-level reading comprehension. You need to be able to spot logical flaws, edge cases, and subtle anomalies in text. Autonomy: Self-starters who are highly organized and can reliably manage their time in a remote setup. Bonus: Background in research, editorial work, data annotation, or tech evaluation. We index highly on people with "good taste" and refined judgment for high-quality content. Note: The wide hourly rate ($22 - $70/hr) reflects the variance in domain expertise, assessment complexity, and location.
How to Apply: Apply here: https://l1nq.com/ai-model-assessment-specialist
Important Next Step: Please check your inbox/spam folder immediately after submitting your application. You will receive an email containing a link to an AI-driven interview. Completing this AI interview is a mandatory requirement to move your application forward.

We're a 4-person boutique consulting shop in Albany, NY building custom web apps for healthcare, legal, and education clients. Looking for a senior engineer to work alongside the founder on production systems for clients.
Stack: Go (Echo, ENT), PostgreSQL, AWS, Cloudflare, Clerk, Alpine.js, Tailwind, Vite, Terraform. We have a proprietary ~1M-line Platform Foundation that anchors most projects.
You: Shipped real Go in production (not "willing to learn"). Comfortable across the stack. Opinions about migrations, RBAC, and not-overengineering. English fluent enough to talk directly with clients.
Process: Paid trial task → 3-month contract → conversion to long-term contractor. No middlemen, no platform markup.
Apply: hiring@yidisconsulting.com with a Go project you're proud of and a brief note on how you'd approach a vertical-slice task touching ENT, an Echo handler, and an Alpine component.
FunnelStory builds a queryable context graph over enterprise data — the infrastructure layer that lets AI agents reason over live customer intelligence. We've built a federated query engine purpose-built for agents, ML models from scratch in Go (health scoring, cohort expansion, process mining, Markov chains, Genetic Pareto optimization), and on-prem deployment infrastructure for enterprise customers. All on a deterministically tested backend.
We need engineers who go deep. The kind who read academic papers to build something novel, then hunt down a performance bottleneck five layers deep in the stack. Go is preferred but not required. Strong math and systems engineering background is a plus. What's required: ability to solve hard problems, use AI tooling to add real value (not slop), and drive work forward independently.
Please reach out to me directly at preetam @ funnelstory.ai with "HN" in the subject.

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.
There are a lot of companies in the auth space, but we feel like we have something special:
* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* our CTO is the founder and still writes code
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Hey, I'm one of Stellar's founders. We're building AI for large contact centers, our primary product is voice.
Contact centers are the last place where companies actually talk to their customers. We listen to calls every week and it's fascinating. AI here helps real people: shorter wait times, 24/7 support, lower cost. We’ve helped companies go from 60 to 98% pickup rate in weeks. We’ve had (human) agents asking us to accelerate our roll out plan because the days with Stellar are so much better than the days without.
We’re all builders. Everybody in our company still writes code. We have one role open:
We are looking for implementation leads that love working with clients. FDEs welcome as well.
This role is perfect if you:
* Want massive ownership at a small team
* Actually enjoy solving hard problems (real-time audio at enterprise scale)
* Think making AI sound human in niche dialects is a fun challenge

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled. Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate.
Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.
Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.
This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.
We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.
Reach out directly with your gh, linkedin, and resume and why you want this position to lucie@markerlearning.com. Please specify your location, if you are interested in full time, contract or open to both. Make the subject "Founding Engineer Application (I am not a bot)".
Preferred Networks is an AI company based in Tokyo working across the stack, from AI chips and computing infrastructure to LLMs and products. You may already know us indirectly if you've used software we've built, such as Optuna or CuPy (or Chainer, back in the day).
We are designing in-house chips (MN-Core series: https://mn-core.com/) and training LLMs (PLaMo series: https://huggingface.co/pfnet), and our team is actively hiring for two roles related to these endeavors:

COVU is an AI-first insurtech startup rebuilding the 20-year-old legacy infrastructure of the $365B+ insurance distribution industry.
We recently announced our $16M funding round (bringing our total to ~$50M) and launched COVU OS. We aren't just slapping an "AI wrapper" onto old software; we built a task-native orchestration layer from scratch. COVU OS converts messy, unstructured insurance workflows (emails, PDFs, manual triage) into defined tasks, dynamically routing them to the right execution layer—whether that's an AI agent, a licensed human professional, or an offshore team.
We are a scrappy, execution-focused team of builders. We heavily encourage using AI tools (Cursor, Copilot, Gemini) in your daily workflow to ship code faster. If you hate spending months in "discovery" and prefer to just build and own production systems end-to-end, you will fit right in.
The Stack:
Data: Snowflake, dbt, Airflow, Python
Product: TypeScript, React, Node.js / Python backends, Cloud Infrastructure
Open Roles:
Staff Full Stack Engineer (Technical Lead): You will be a foundational technical leader shaping the architecture of COVU OS. Expect deep, architecture-level design work paired with heavy, hands-on IC contributions.
Sr. Full Stack Engineer: You will own complex product surfaces end-to-end, building out the agentic orchestration layer, user interfaces, and enterprise API integrations.
Data Engineer(Remote): You'll be the primary builder of our "Golden Policy Journal," transforming highly complex, messy carrier data into our single source of truth using Snowflake, dbt, and Airflow.
Sr. Product Manager (COVU OS): You will own the roadmap for our core operating system. We need a highly technical PM who can dive into the weeds of agentic workflows and write specs that engineers actually want to read.

Company: Series C fintech. We're building the next generation of financial tooling to help business owners succeed. Our solution blends banking, bookkeeping, taxes and payments into an all-in-one solution to help save our users time, stress and money -- so they can focus on what matters to them; running their business.
Role: Small (~20 eng) team, 1-person platform function. You’d operate with immediate ownership across reliability, incident response, security/compliance (bug bounty, PCI/SOC2), CI/CD, observability (Datadog), and core infra on GCP (Mysql/Spanner/Redis/K8s/ etc). Also supporting launches end-to-end (from mobile app down to networking layer), and finding opportunities to improve developer velocity. It's a pretty broad role, but with that comes a lot of room to grow.
I worked in this position for a few years, if it looks interesting send me an email -- left some clues how on prior months posts.

Full time engineering role (Remote, US person required; Pacific time zone)
Stack: C#, Python, Gemini API on Windows, lots of legacy systems/constrained enterprise environment. Health systems experience preferred. Understanding of cost effective, reliable LLM API use. Should be flexible: do PM-like work with less-technical client domain experts, solve problems end to end, willing to data cleaning and detailed work for client goals and security/compliance gruntwork, even when it's not technically elegant. Self motivated, willing to understand legacy and undocumented codebases, but also willing to take instructions.
Ideal candidate has real (pre-Claude Code) experience, but is ready to do fast iteration in post-AI world, while actually reading what the AI does. We're ok if your stack is different, if you're both technically mature and up to date on modern fast-turnaround AI-based development. Probably in the 5+ year experience range.
REMOTE anywhere, project based or initially part time: startup generalist hacker, maintain systems and websites, code one-off prototypes. Should be good enough to code without an AI in a few languages, but an effective AI harness coder. Can do a small but complete app/project end to end, including basic marketing. 2+ year exp or a new grad with a good portfolio or major project; happy to consider more experienced person. Good role for someone who's working on their own startup to pick up some side money and experience. Projects could be anything from game-like apps/novelties to voice tools to utility apps.
REMOTE anywhere, project based or initially part time: help on some more experimental mathy projects. M.S./Ph.D. in statistics, physics or related, with pragmatic programming experience. Possible projects: gaussian process modeling; designing evaluation metrics; compression; Bayesian tools for radiology imaging. May be good for a grad student part time. This is the fun stuff the founder would rather be doing himself if he had the time.
REMOTE (US person) Half-time remote admin/chief of staff type: deal with bookkeeping, compliance, communications, social media, phone calls - save us time on everything non-technical. Should be effective AI user; should have some relevant experience supporting tech business.
