Linux Kernel Consultant (Remote/Anywhere)

About this roleShip kernel code that runs on millions of devices worldwide. You'll work directly on upstream Linux development for a flagship consumer product while contributing to the broader kernel community. This isn't just maintenance work, you'll be solving hard problems and your code goes upstream. This role suits an engineer who wants to go deep: you will have the space to develop genuine subsystem expertise, build your upstream profile and grow into technical leadership over time.This role combines deep technical work with collaborative consulting. You will partner with client engineering teams to solve their toughest kernel challenges while championing upstream-first approaches.Location: Fully remote (preference for EU or East Coast US hours)Travel: Optional conference attendanceWhat you'll actually doUpstream First: Contribute directly to mainline Linux kernel development: schedulers, power management, device drivers and core subsystemsReal-World Impact: Support and optimise Linux for extremely popular consumer devices used by millions of peopleSolve Hard Problems: Make Linux do things it can't currently do. Push the boundaries of what is possible to mould Linux to suit new use cases. Tackle device failures without the luxury of a stack trace, relying on experience and intuition. Just because Linux doesn't do it currently, doesn't mean we can't invent it.Community Collaboration: Work with upstream maintainers and represent Collabora at conferencesClient Partnership: Translate customer needs into technical solutions while advocating for upstream-first approaches. You'll help clients understand why investing in upstream benefits their long-term goalsNavigate Constraints: Balance technical excellence with real-world pressures: customer deadlines, hardware limitations, business priorities, while keeping code quality highBe a Technical Advisor: Explain complex kernel decisions to product teams, provide honest timelines and build trust through transparent communicationWhat we're looking forRequiredProduct 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 stepsSolid Linux kernel development experience,you have spent meaningful time working in the kernel and are comfortable navigating unfamiliar subsystems independently.
