Contribute directly to mainline Linux kernel development: schedulers, power management, device drivers and core subsystems
Support and optimise Linux for extremely popular consumer devices used by millions of people
Make Linux do things it can't currently do
Work with upstream maintainers and represent Collabora at conferences
Translate customer needs into technical solutions while advocating for upstream-first approaches
Balance technical excellence with real-world pressures: customer deadlines, hardware limitations, business priorities, while keeping code quality high
Explain complex kernel decisions to product teams, provide honest timelines and build trust through transparent communication

Product support experience, you are comfortable diagnosing and resolving issues reported by end-users which often require dedication to reproduce from vague bug reports and limited reproduction steps
Solid Linux kernel development experience, you have spent meaningful time working in the kernel and are comfortable navigating unfamiliar subsystems independently. You do not need to have seen everything, but you should know how to find your way. We are looking for someone who is still building their reputation in the upstream community and wants a role that accelerates that.
Strong English communication skills, both spoken and written for patch reviews, documentation and client discussions
Self-directed work style
you thrive in a remote, asynchronous environment
Upstream contribution history, we know not every employer makes this easy. If you haven't had the opportunity yet, we'll help you build that profile as part of the role
Consultancy or client-facing technical background, you know how to balance technical excellence with business constraints, explain kernel internals to product teams, manage expectations across multiple projects and advocate for upstream solutions while respecting customer timelines
Experience with schedulers, power management, Bluetooth, WiFi or audio subsystems
Familiarity with CI/CD for kernel testing (KernelCI, Jenkins, LAVA)
Background in BSP development or board bring-up
Distribution experience (Arch, Debian, Yocto, Buildroot)
Rust programming skills
