AI Summary

Senior Systems Engineer focusing on Linux kernel-level networking, Docker, and multi-architecture performance; develops umbrelOS core components, ensures stability, security, and compatibility across x86 and ARM64.

About this 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.

  • 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
