Building Langfuse
Join the team building the leading open-source LLM engineering platform
View Open Positions →
While LLMs improve a lot, we don’t see enough applications in production. Building these applications requires a new workflow of continuous monitoring and evaluation that we enable with Langfuse. We are seeing strong traction (see metrics below), thus it is the right time to grow the team to build out our backend systems, product, and how we communicate with developers.
We have raised a $4M seed round from Lightspeed, General Catalyst, Y Combinator and angels. We are growing fast (see metrics below) and work with some of the best AI teams such as Samsara, Twilio, KhanAcademy and Rocket Money.
If complex technical problems & great developer experiences excite you, we’d love to hear from you.

How we operate
Open Source
The future of AI must be open. It's not only about licensing, but about building a community far bigger than any single company. We are building in public.
High Trust / Extreme Autonomy
We own work end-to-end. Everyone runs their part of the product, including planning, design, implementation and support. We removed any bureaucracy trusting you to do the right thing.
Strong In-Person Engineering
The things we build are complex and are moving really fast. We are playing to win. We believe this takes a level of communication that only in-person work can achieve.
Deep Work
We have only 2 scheduled meetings per week: 15 min planning on Monday, 60 min demo on Friday. We collaborate where it makes sense, but we get impatient with time not shipping.
Agency & Taste
On the team we care deeply about agency and taste. It's about knowing what good looks like and shipping improvements without needing permission.
A-Team
We want to build a small group of high leverage individuals. Everyone on our team earns their spot. We strive to raise the bar with every addition. Many on the team have led companies/teams before but are excited about shipping as an IC.
