Langfuse - Senior Product Engineer

You will also have direct exposure to how cutting-edge LLM applications are built. The users you serve are some of the best and most ambitious software engineers leveraging Langfuse to improve their applications. Deeply understanding the problems they solve will help you design the best possible product and along the way makes you an expert on LLM engineering yourself.

YOU WILL GROW AT LANGFUSE BY

• Own features end-to-end: from talking to users, to writing the spec, to shipping the code and docs, to writing the changelog post https://langfuse.com/changelog with your name on it. To give you a sense: recent features a single engineer owned include the Langfuse for Agents https://langfuse.com/changelog/2-langfuse-for-agents release (new trace views, agent graphs, semantic span labels), the TypeScript SDK v4 https://langfuse.com/changelog/2-typescript-sdk-v4-ga rewrite on OpenTelemetry, and managing dashboards via API/CLI/MCP https://langfuse.com/changelog/2-dashboard-and-widget-operations-in-api.
• Work across the full stack: and we mean full. Our surface area is wide: React frontend, Next.js backend, ClickHouse analytics, Python and TypeScript SDKs, public docs, Terraform modules, and more. You'll touch whatever the feature needs. One week you might be writing a new ClickHouse query for cost analytics, the next you're designing an SDK API, the next you're building a new rust worker for faster data processing.
• Talk to users constantly: jump on calls, respond in community channels, and route support requests. At Langfuse, support is how we build conviction about what to build next. Our handbook says it best: support by engineers is a core value proposition.
• Write public documentation about the features you own. At Langfuse, docs are product.
• Ship publicly during Launch Weeks: we've run four Launch Weeks https://langfuse.com/blog/2-launch-week-4 so far, dropping a new feature every day for a week. Engineers present the features they built to the community.

WHAT WE’RE LOOKING FOR

• Someone who has built features or even entire products from scratch end-to-end
• Experience building and shipping user-facing products end-to-end, ideally in TypeScript/React and with exposure to data-intensive backends
• Someone who can manage projects themselves. You know how to develop strong conviction about what to build and how to ship it.
• Taste for great developer experience: you care about API design, UI details, and clear documentation
• Interest in open source software and genuine excitement about talking to developers about their problems
• Thrives in a small, accountable team where your output is visible and matters
• CS or quantitative degree preferred

Bonus points:

• Experience with ClickHouse, analytics databases, or building complex data visualizations
• Former founder or early startup experience
• Contributions to popular open source projects
• ML/AI background or familiarity with the LLM framework ecosystem

No candidate checks all boxes. If you feel you are a good fit for this role, please go ahead and apply.
