Koton is a small, high-trust team where your impact is visible from day one. Capable people get space quickly and can shape real trading outcomes early. We keep things small and flat, communicate directly, iterate fast, and stay sharp about priorities, with ideas moving freely between people and teams.
Part of our core team is based in Brno, with some of us working from all over. In-person onboarding helps you start well connected. Beyond that, location is flexible, on-site or EU preferred, with hybrid or remote possible depending on the person.
There is a rare combination on offer: the chance to help build something large, while staying close enough to feel it is within easy reach. No corporate layers. Direct impact and direct feedback.

How we work
The best argument wins
Ideas don't need a sponsor or a committee, and titles don't decide who is right. If you can make the case, you get to try it.
We learn fast
Markets tell you quickly whether you were correct, which keeps us honest. We would rather test something and learn than debate it for a month, and being wrong early is treated as information, not failure.
Across disciplines
Traders, quants, and engineers sit close together and work on the same problems, so you pick up things well outside your own discipline. Most of what people learn here they learn from each other.
A friendly place
Informal and easy to be around. Serious about the work, relaxed about everything else. Nobody has to navigate politics to get something done.
We give back
We put a share of what we make into evidence-led philanthropy. It says something about how we think and it is also a part of why people stay.
