Langfuse (now part of ClickHouse) | Product Engineers & Backend Engineers
Location: Berlin / EU-remote (~1 week onsite every 2 months; travel covered) Type: Full-time Compensation: €70–130k + ClickHouse equity
About the Role
Hi, I'm Max, CTO and co-founder. Langfuse is the open-source LLM engineering platform—covering tracing/observability, evals, and prompt management—used by tens of thousands of teams to ship, debug, and improve their LLM and agent apps.
Earlier this year, Langfuse joined ClickHouse ($400M Series D led by Dragoneer, $15B valuation). That gives us the best of both worlds: startup-speed, ownership, and roadmap control, backed by the scale, resources, and equity upside of a category-defining infra company.
Our Focus
Right now, we are focused on helping customers segment their traces, surface insights from them, and ship changes to their agents faster. We are building observability at serious scale, combined with the product surface that engineers actually live in day-to-day.
