Open Source LLM Engineering Platform that helps teams build useful AI applications via tracing, evaluation, and prompt management (mission, product)
We have the chance to build 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: >2k customers, >14M monthly SDK downloads, >6M docker pulls
We raised money from world class investors (Y-Combinator, Lightspeed, General Catalyst) and are default alive by making more money than we spend
We're a small, engineering-heavy, and experienced team in Berlin and San Francisco (how we work)
Our CTO Max is going nowhere.
We are putting this out there because most people at Langfuse have founded or run teams before but love shipping code as IC again. Check Hassieb, Steffen, Nimar, some more joining soon..)
We are investing a lot in building one of the talent densest engineering teams in Europe.
We think we really have a shot at the goal here but we can't do it alone.
You might be perfect if you:
Used to run the show, but now want to ship code again
Enjoy the adrenaline of a “can we do this by tomorrow?” sprint
Have a vendetta against over-engineering (and meetings)
Low ego about roles and titles
Perks:
Our customers are building extremely sophisticated AI apps
Strong product market fit
Too much to build
Super small team
Largest open source LLM ops platform
Be pushed to push AI / LLMs to their limits to get more done
Extreme autonomy, it will feel like running your own show
Your boss is probably younger than you
You get to say “back when I was a CTO…” unironically
Above market compensation + equity
Just ping us somewhere or leave your email via the form (not an application, more like networking).
Please advise: Our engineering team is based in Berlin and we require in-office culture. We know it's not for everyone, but it's what we believe in.
