Our development team has 16 people. We work in an agile environment, develop iteratively, and take testing seriously. We currently have three specialized product sub-teams — Execution, Data, and Infrastructure — each focused on developing and running their core domain.
📊 Who we're looking for
This role is for our Execution Platform team, where we have three experienced Python developers. We tackle challenging backend problems here — performance and platform optimization, scalability, and system robustness.
🔥 Want to help build a platform that has a real impact on our traders' success? Come join us! 🚀
Building backend applications in Python (asyncio, FastAPI, Django, RabbitMQ)
Maintaining and shipping new features to our internal execution platform
Evaluating and integrating third-party solutions
Deploying applications to production (Kubernetes + Argo CD)
Talking to traders and analysts — your internal customers — about the features they need
Taking turns with the rest of the team on platform support
Joining SCRUM ceremonies — but don't worry about pointless meetings where you wonder why you're there. For us, it's all about handling business priorities efficiently, not following SCRUM by the book.
Snacks, 5 weeks of vacation, 5 sick days, and a Multisport card
You have backend development experience, ideally in Python or one of the compiled languages (C/C++/Rust)
You know SW development best practices (Git, testing, KISS, DRY, YAGNI)
You're into high-performance applications, but you're equally comfortable with standard Python backends
You care about more than just writing code — you can give feedback to teammates, and you're open to taking ownership of a project
You think about the architecture of what you're building, you're not afraid to share your opinion in team discussions, but you're also open to other people's perspectives
Before diving in, you stop to think whether someone's already solved the problem — no reinventing the wheel
You have a decent level of English, which you'll need for communicating with some of our traders
Have experience designing high-performance or distributed system architectures
Know Rust
Have an interest in capital markets
