Your Tasks:

• Master the Build and Release Pipeline: Evolve and improve the infrastructure and
  processes used to build, test, and release our Linux distribution, ensuring reliability and reproducibility.
• Be the Ultimate Escalation Point: Act as the go-to expert for complex, low-level system issues. Perform deep-dive troubleshooting, debugging, and root-cause analysis across both software and hardware.
• Consult and Empower Development Teams: Guide internal project teams on how to best leverage the Roche Linux platform.
• Proactively Drive Improvement: Constantly seek out opportunities to enhance our

• Advanced English is mandatory; German is a welcome bonus.

Nice to Have:

• Proficiency in a systems programming language like C or C++.
• Experience with embedded systems, the ARM platform, hardware drivers, and low-level hardware/software integration.
