• Intermediate or higher English proficiency, both written and spoken.

Nice to have

• Experience with RPM/SRPM or Debian kernel packaging.
• Familiarity with Docker, QEMU, Jenkins, or continuous integration systems.
• Experience designing kernel tests, analyzing core dumps, or investigating system regressions.

Benefits

• Full remote work environment with flexible working hours and the ability to work from anywhere worldwide.
• Opportunity to work on challenging Linux security and open-source infrastructure projects.
