Tech stack: (frontends) Swift/Kotlin/TypeScript, (backend) Python/Kotlin/Postgres/Dynamo, (infra) AWS/k8s/Terraform.
We're always hiring for engineers. A few roles below:
Senior Engineering Manager, Monetization: https://careers.duolingo.com/jobs/8414653002
Senior Android Engineer: https://careers.duolingo.com/jobs/8217266002
Engineering Manager, Chess: https://careers.duolingo.com/jobs/8385137002
Senior iOS Software Engineer: https://careers.duolingo.com/jobs/8318257002
Base salary: $200K-300K for Senior Eng Manager, $177K-$240K for the others (+equity).
Perks: free lunch, 2-week winter break + 20 days of flexible time off.
Lift AI builds software for the elevator industry, where paper inspection reports and faxed maintenance tickets are still normal. Almost no one is building software for this market. We manage ~5,000 properties and have 1,000+ IoT deployments on elevators across the US. The platform handles asset management, maintenance workflows, contract tracking, and an AI pipeline that extracts structured data from elevator industry documents. Django/PostgreSQL backend, React/TypeScript frontend, all on AWS. The CEO's family has been in the elevator industry for 40 years — we're not outsiders guessing at what the market needs.
You'd be our third engineer. The team is me (CTO, I write code daily, Central Time), one engineer who's been here two years and knows the domain well, and our Chief of Product who handles the PM side. No QA team, no DevOps. You own what you build.
First project: we acquired a field maintenance product that currently runs on Firebase/Firestore. You'd design the migration of its backend onto our Django/PostgreSQL stack, including figuring out a replacement for Firestore's offline sync (we're looking at ElectricSQL). You define the API contract, our other engineer builds the frontend against it. Beyond that, we're actively building AI features. One example: an invoice dispute agent that communicates directly with service providers. You'd help architect those.
Stack: Django 5 / DRF, PostgreSQL, Redis, Django Q, React Router v7, TypeScript, MUI, AWS (CDK, ECS Fargate, ElastiCache, RDS), GitHub Actions. AI features use Claude, OpenAI, and LangChain.
We're async but not siloed — Slack, GitHub PRs, and Linear are where most collaboration happens, with the occasional video call. No standups. We follow Shape Up with 4-week cycles. I review architecture proposals for your first ~90 days, then you own your domains. No on-call rotation. We don't do evening releases, and when something rare breaks, everyone pitches in.
$100K base + 0.50–0.75% equity. We have ~5,000 customers and growing revenue, so the equity isn't a lottery ticket. $100K is below big-city market rate and we know that. We're not focused on titles or hierarchy. Growth here means the scope of what you own keeps expanding, and comp grows with it.
5+ years experience. Python (Django, Flask, or FastAPI) and React/TypeScript in production. You've built something from architecture to deployment without someone telling you how. If you've been engineer #2-5 at a startup, or you're a senior engineer tired of process overhead, or you're at an agency and want to go deep on one product, this is that kind of role.
hiring@liftai.com — send something you've built that you're proud of, and tell us why.
We are building AI-powered spatial audio tools that make Dolby Atmos mastering accessible to artists, labels and engineers. Seed-stage, fully remote (PT to CET).
Looking for a hands-on CTO to ship code and lead a small team (2–3 engineers, growing). You'll build scalable backend services for AI-driven audio processing, integrate DSP/ML models into production and set technical vision.
*Requirements:* - 3+ years managing engineering teams (5–15 people) - Strong Python production experience (5+ years) - Experience with audio/DSP libraries (NumPy, Librosa, SciPy, Pedalboard) - Cloud infrastructure and ML ops (AWS/GCP) - Passion for music and audio
*Comp:* $180K–$200K + equity + benefits (US-based)

Hi there! At Veho, we don't sell software. We ship packages. Lots of them. We have all of the interesting problems that crop up when running twinned distributed systems in AWS and the real world. It's pretty great.
We're hiring staff-level folks (L4+) in NYC and Boston: Data Scientists, Data Engineers, Mobile Engineers, and Backend Engineers (typescript).
Personally, I'm hiring a Staff Data Engineer with the depth of experience to be a technical lead and mentor for the Data Platform team, while also shipping code. You will need to understand distributed data systems both intellectually and at an instinctive, emotional level. You should have Opinions about the wild boar book. You should probably also be comfortable writing and debugging English, SQL, and Python.
If that sounds like you, I really want you to apply for the Staff Data Engineer role on our career page. Our inbound applications are reviewed by humans.
With apologies that our first interaction requires this silliness: including one of the 7-digit numbers from the "ROS Calculator" on Veho's website in the appropriate box will heavily bias me towards believing you are a human being. That's more of an advantage than it may seem! It's worth the thirty seconds. It would also speed things along if you populate the "Location" field to confirm you are aware this is an in-office role.

We’re a small UK-based free-to-play gaming company with a distributed EU team, growing fast after recent success and scaling our platform. We’re looking for a FE/Fullstack role, from mid-senior to senior engineer with at least 5+ years of experience.
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. We value clear thinking and communication, you should be comfortable sketching simple architecture or flow diagrams (boxes and lines, nothing formal) to explain your ideas.
You’ll also be asked to write SQL and some Java Controllers that access data. It’s ok if you don’t know Java, but our controllers are written in Java and you’ll need willingness to learn.
Our stack includes Java, Python, TypeScript, Angular, SQL.
To apply, please send an email to jack[at]splash.tech with the subject “FE/Fullstack 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.
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 comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), 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 hooks.
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 get paid to write source code 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.

Mainstay is a market intelligence platform for large real-estate operators. We’re an AI-native company focused on turning complex, messy, real-world data into systems customers actually trust to make financial decisions. Mainstay was incubated at Opendoor, spun out in 2024, and recently raised a Series A led by Khosla Ventures.
We’re hiring a Senior/Staff Software Engineers, but we care more about ownership and judgment than title.
You'll work on:
- Designing and evolving foundational data models used across the platform
- Building backend services, workflows, and automation systems end-to-end
- Applying AI/LLMs pragmatically (automation, reasoning over messy inputs, decision support)
- Shipping user-facing product features tied directly to real customer workflows
- Owning problems from idea → production → iteration
Stack: Python, TypeScript, React, AWS
Check out the roles at: https://www.mainstay.io/careers
Engineers can't keep up with their production environments: dozens of services, dashboards everywhere, alerts firing constantly. The information to diagnose most issues already exists, but finding it takes longer than fixing the problem. And the more AI-generated code ships, the more services get deployed by people who won't be around to debug them.
Cleric connects to your existing observability stack, autonomously investigates production incidents, and tells engineers what's wrong. We're well funded with years of runway, a small team of AI and infrastructure veterans in SF, growing quickly. Stack: Python, Go, LLMs, Kubernetes.
Some of the problems we work on:
There's no test suite in production. When the AI says "the root cause is X," how do you verify that? You can't A/B test diagnoses. Ground truth labels don't exist. We build evaluation systems that track resolution outcomes over weeks and correlate fixes with diagnoses to build statistical confidence.
When something breaks, everything looks broken. Database latency spikes, five services throw errors, CPU goes up, logs explode. When an agent sees 47 anomalies at once, it needs to figure out which one is the root cause and which are symptoms, across systems with feedback loops, hidden dependencies, and non-obvious temporal relationships.
A single investigation might need six hours of metrics across 50 services, 10GB of logs, 10,000 distributed traces, the last 30 deployments, and the relevant runbooks. LLMs have finite context windows. What's relevant isn't known until you investigate. Getting retrieval wrong means wrong conclusions or exploding costs.
We're hiring:
- Staff Software Engineer, AI: You build the core agent. Reasoning, evals, self-improving feedback loops. You debug agent behavior by tracing reasoning and tool choices to understand why the agent made a specific decision. You build the systems that make a non-deterministic agent reliable, and push it to handle increasingly complex incidents.
- Staff Software Engineer, Product: You define what an AI SRE should actually be. When AI handles the reasoning, how do engineers stay sharp for cases it can't handle? How do you build trust when someone needs to verify agent conclusions at 2AM? You answer these by embedding with customers during real incidents, running experiments, and making the technical calls to ship what works.
- Software Engineer, Backend: You build and scale the investigation platform alongside our senior engineers. Integrations with Datadog, PagerDuty, and dozens of observability tools. Agent reasoning pipelines. Runtime systems that handle real-time data streaming at scale. You'll ship customer-facing functionality across the stack.
- Founding Marketer: Software engineers are allergic to AI hype. Our users already love the product. The challenge is reaching the next thousand teams without setting off their BS detectors. You build the marketing function from scratch: programs, pipeline, infrastructure. You need a technical foundation and the ability to hold a 30-minute conversation with a platform engineering lead without getting lost.
- Staff Designer (Remote): The interfaces for AI agents don't exist yet. How do you make autonomous reasoning legible without overwhelming? You own design across brand, product, and marketing, defining the visual language for a new category.

Job description: https://ipify.notion.site/Senior-Python-Developer-37de517efa...
Company website: https://www.ipify.app/
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
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.

WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re looking for senior software engineers to build our data platform and help us ingest and model messy, unstructured data into insights and actionable intelligence. At the heart of this is a 50m+ entity knowledge-graph with 200m+ relationships represented - and we need your help to build a system that can scale this up by an order of a magnitude. Today, we mostly use Python, Postgres, Airflow and Pyspark.
If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.
