‍💪 Who we're looking for:

A senior Python developer with experience designing complex systems
Ideally someone with background or interest in hardware or embedded development
A system-oriented thinker who understands context and long-term impact
Comfortable working in a Unix/Linux environment and open source culture

A chance to work on a unique project with an agile team focused on developing cutting-edge solutions for secure embedded electronics
Direct impact on an open source project used in real-world semiconductor development
Opportunity to bridge software and hardware in an architecture-driven role
Work remotely, in a hybrid setup, or from the office – whatever suits you best. We’re a team that values autonomy and deep technical focus
Monthly in-person team meetups in Prague for planning and collaboration
