Senior Product Engineer: End-to-End Open Source Features

Langfuse is hiring product engineers to own features end-to-end, from user research and specs to shipping and docs. You will work across the full stack—React frontend, Next.js backend, ClickHouse analytics, Python/TypeScript SDKs—and engage directly with users to understand their problems.

You will design and ship features for a rapidly growing open-source platform that is MIT-licensed, with a strong community and a track record on GitHub.
