Write documentation and integration guides. At Langfuse, docs are part of our core product. When you ship a new integration, the guide ships with it. You'll own the integration docs, quickstart tutorials, cookbooks, and migration paths that help developers get started in minutes.
Requirements
Strong in Python and/or TypeScript. You write clean, reliable code. You don't need to be a systems-level performance expert, but you care about code quality and understand that integrations run inside other people's production systems.
Product-minded engineer. You think about the developer who's going to use your integration at 11pm trying to ship a feature. You obsess over the getting-started experience: how many lines of code does it take? Is the error message helpful? Does the docs example actually work?
Self-directed and motivated. You know how to develop conviction about what to build
Additional Information
About Langfuse
Open Source LLM Engineering Platform that helps teams build useful AI applications via tracing, evaluation, and prompt management ( mission , product ). We are now part of ClickHouse.
We're building the "Datadog" of this category; model capabilities continue to improve, but building useful applications is really hard, both in startups and enterprises.
Largest open source solution in this category: trusted by 19 of the Fortune 50, >2k customers, >26M monthly SDK downloads, >6M Docker pulls.
We joined ClickHouse in January 2026 because LLM observability is fundamentally a data problem and Langfuse already ran on ClickHouse. Together we can move faster on product while staying true to open source and self-hosting, and join forces on GTM and sales to accelerate revenue.
Previously backed by Y Combinator, Lightspeed, and General Catalyst.
We're a small, engineering-heavy, and experienced team in Berlin and San Francisco. We are also hiring for engineering in EU timezones and expect one week per month in our Berlin office ( how we work ).
Why Integrations Engineering at Langfuse
Your work puts Langfuse into developers' hands.
Our SDKs are downloaded 26M+ times per month, and for many developers the first thing they touch is an integration - a few lines of code that connect their favorite framework to Langfuse. When that experience is seamless, they're wow'ed. When it's not, we might have lost them. You'll own that critical first impression across 40+ framework integrations.
You'll live at the frontier of LLM application development.
The AI framework ecosystem moves fast - new agent frameworks, orchestration libraries, and model providers emerge every week. You'll be among the first to instrument them, giving you unmatched exposure to how cutting-edge AI applications are built. The developers you serve are some of the most ambitious software engineers in the world, and working closely with them will make you an expert on LLM engineering yourself.
Everything you build is open source and immediately visible.
All Langfuse integrations are MIT-licensed. When you ship a new integration or improve an existing one, thousands of developers benefit the same day - and they'll tell you about it in GitHub issues, on Twitter, and in our community channels.
