Teams at Langfuse

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.

Build and maintain growth-focused product features and analytics. Own data stack (PostHog, BigQuery, DBT, Metabase), run experiments to improve funnel and activation, ship full‑stack improvements across frontend and backend, and create growth loops to increase adoption and expansion.

Own and scale the ingestion pipeline and backend abstractions for high-throughput AI tracing data. Optimize ClickHouse schemas and queries, operate Langfuse Cloud and self-hosted deployments, and build infrastructure-heavy features that enable product engineers to ship data-heavy capabilities.
