Senior Python Developer (+ C++)

We’re not a typical software development team. Instead of working on business features, our goal is to keep a large, shared library stable and consistent. The library is developed by more than 100 contributors and used across different environments and technologies.

Our daily work involves solving complex technical problems. We often deal with compilers, system quirks in Linux and Windows, and other deep technical topics that require careful research and creative thinking.

We’re also responsible for setting up automation and defining rules for development and release processes. The project is large and part of a highly regulated financial institution, so the work can be challenging — but also very rewarding for those who like solving difficult engineering problems.
