Senior Python developer

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! 🚀

What your day-to-day will look like:

• 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.

What we offer:

• Snacks, 5 weeks of vacation, 5 sick days, and a Multisport card

• Brand new, modern offices in Karlín
• Hybrid setup — ideally 3 days on-site
• Regular sessions with a company therapist / coach
• English lessons with a native speaker
• Internal training and contributions toward technical conferences

A bit about you:

• 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

Ideally, you also:

• Have experience designing high-performance or distributed system architectures

• Know Rust

• Have an interest in capital markets
