Teams at Langfuse

As a Product Engineer, you'll build and maintain integrations with various AI frameworks, design new patterns, contribute to core SDKs, and engage with the developer community to enhance the LLM application experience.

Design and build critical IAM and billing infrastructure for Langfuse, enabling secure user management and accurate usage-based invoicing. Collaborate with teams to ensure seamless integration of authentication and authorization systems, while supporting self-hosted deployments for enterprise clients.

Own and ship full-stack product features end-to-end for an open-source LLM observability platform: design specs, implement frontend and backend work (TypeScript/React, ClickHouse, Python), talk to users, write docs, and improve developer experience while collaborating in a small engineering team.
