• Upstream First: Contribute directly to mainline Linux kernel development: schedulers, power management, device drivers and core subsystems
• Real-World Impact: Support and optimise Linux for extremely popular consumer devices used by millions of people
• Solve 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 conferences
• Client 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 goals
• Navigate Constraints: Balance technical excellence with real-world pressures: customer deadlines, hardware limitations, business priorities, while keeping code quality high
• Be a Technical Advisor: Explain complex kernel decisions to product teams, provide honest timelines and build trust through transparent communication

Required

• 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

Nice to have

Compensation & Benefits

• Competitive salary - Salary is location-dependent and benchmarked against local market data. We ask candidates to share their expectations during the application process and engage with those honestly
• Conference attendance - we cover expenses and encourage speaking opportunities
• Open source time - contribute to projects you care about
• Office setup budget
• Sabbatical/Retention of Services, available after five years continuous service
• Co-working policy - support for working outside home
• Wellness assessments - biannual well-being assessments with a trained mental health specialist

Work Environment

Morning (your timezone)

• Review overnight mailing-list discussions on your subsystem(s)
• Triage new customer issue reports
• Respond to client question about kernel panic they're investigating
• Pair debug session with colleague on tricky scheduler behaviour

Midday

• Deep work: finish patch series for power management optimisation
• Quick video call with customer team to explain your proposed approach and timeline
• Review and test colleague's patch before they submit upstream

Afternoon

• Respond to upstream maintainer feedback on your RFC patch
• Update client on progress, discuss trade-offs between fast fix vs. upstream-ready solution
• Join optional team "office hours" to discuss architecture decision
• Write kernel commit message that explains the "why" for future maintainers

Some days are deep technical work, others involve more client communication. You'll balance both based on project needs and your strengths.
