One of the coolest roles we've had: experiment with cutting-edge AI tools to make talented engineers faster and more effective. Hands-on, experimental, operating at the frontier.

Fanvue is a fast-growing creator monetisation platform — AI-powered, creator-first (Series A, $100M+ ARR, triple-digit YoY growth), supporting hundreds of thousands of creators and millions of fans.

What you'll do: Define and roll out our AI-assisted dev stack (Cursor, Claude Code, etc.) across IDEs, PR workflows, and CI. Build MCP servers and AI-ready infra for context-aware code generation. Enable parallelised workflows, agent skills, and AI-assisted reviews. Establish best practices for safe, consistent AI-assisted coding. Track and report measurable impact. Evaluate emerging tools with clear success criteria.

Who you are: Strong software engineering background with TypeScript in production. Hands-on with AI coding tools (Cursor, Claude Code, Aider, Copilot). Experience with MCP servers. Solid LLM fundamentals (RAG, embeddings, fine-tuning). Comfortable with GitHub workflows and CI/CD. Autonomous, experimental, outcome-focused.

You'll thrive if you want to make engineers dramatically more effective, enjoy rapid experimentation, and own outcomes. You'll struggle if you prefer fixed roadmaps or need heavy direction.

Hermes Health | ONSITE | Venice, CA | Backend Engineer | Full-time | hermeshealth.com

Hermes Health is building a platform to connect identified medical data sources. We are looking for a Rust backend engineer.

However, we are moving the frontend to Rocket via maud+Datastar (similar to HTMX) in order to adopt a "microlith" architecture. Familiarity with event sourcing is recommended, but not required.

This is an in-person position, although we WFH on Fridays and are very flexible on other days as needed. Healthcare and dental available.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

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.

Count | Senior Software Engineer | REMOTE (UK/Europe/US East Coast) | Full-time | £100–140k (or local equivalent) + Equity | https://count.co

Count is an infinite, real-time canvas where SQL, Python, and low-code query cells live side-by-side with visualizations and freeform whiteboarding. It replaces the traditional linear notebook with a collaborative space for modeling, analysis, and presentation.

Under the hood, we've built a custom WebGL rendering engine, data visualization library, graph-based modeling layer, and horizontally scalable compute engine (DuckDB-based) that dynamically shifts execution between browser and server to minimize latency and reduce database load.

You'll help evolve the core platform: integrating agentic workflows into data exploration, pushing the performance limits of our distributed execution layer, and building powerful new analytics experiences used daily by customers. You'll have high autonomy and ownership over major parts of the product and technical roadmap, from architecture through production.

Trunk | https://trunk.io

Developer Marketing Lead - Remote friendly | Senior DevRel Engineer - San Francisco| Technical Lead (CI & Test Data Platform) - San Francisco | Sr Platform Engineer - San Francisco

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

  *Flaky Tests: Detect and eliminate Flaky Tests.

Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions
