• Comfortable with GNU/Linux, the command line and shell scripting
• Solid fundamentals in algorithms and data structures
• English at B2 level or above
• Proactive and able to work independently

Required skills

• Git for development and patch/branch management
• Nice to have: RPM or DEB packaging experience, CVE research or security patching, debugging with GDB and strace, broad awareness of AI-assisted development tooling

What we offer

• Fully remote work with flexible hours, paid vacation, 10 national holidays and unlimited sick leave
• Compensation for private medical insurance, co-working and gym/sports reimbursement, and a budget for education
• A chance to win a reward for the most innovative idea the company can patent
• Learning AI-assisted development workflows across the full development lifecycle
