About the role

This role requires a strong understanding of Linux systems, particularly at the kernel level, networking, Docker, and the ability to optimize for both x86 and ARM64 architectures.

In this role, you will:

  • Develop and maintain the core components of umbrelOS, focusing on performance, stability, and security across different hardware architectures.
  • Ensure optimal integration and performance of umbrelOS on the Umbrel Home.
  • Design and implement system-level enhancements.
  • Conduct rigorous testing and debugging at the kernel level to handle system updates and compatibility issues.

We hope you

  • Can autonomously figure out solutions to engineering challenges
  • Value clear and frequent communication (we do a lot of reading and writing)
  • Enjoy being a generalist and are not tied down to a specific framework or surface area of our codebase
  • Are naturally curious and willing to learn something they don’t have experience in
  • Have good judgement of when to ship: perfect is the enemy of good
