About this role
Ship 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 attendance

What you'll actually do
What we're looking for
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
- 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
Nice to have
What we offer
Compensation & Benefits
We offer a competitive benefits package tailored to each country in which we have employees, plus a core global benefit offering accessible to all Collaborans. Our core benefits include:
Work Environment
Growth & Impact
Culture & Values
A day in the life
Morning (your timezone)
Midday
Afternoon
Some days are deep technical work, others involve more client communication. You'll balance both based on project needs and your strengths.
Our Interview Process
We respect your time and provide a clear, structured process:
- Application Review (within 1 week) - we look at your code and contributions
- Initial Chat (30 min) - casual conversation about your experience and our work
- Technical Interview (2 - 3h)
- Technical Deep-Dive - discuss kernel architecture, past debugging challenges and how you approach problem-solving (no whiteboard coding)
- Code Review Session - review real patches together, discuss trade-offs
- Client Scenario Discussion - talk through a realistic customer situation: balancing technical debt, timeline pressure and upstream goals. We want to see your thought process, not a "right answer"
- Head of Open Source Software Consulting team Discussion (60 min) - meet the Head of Open Source Software Consulting team, ask about day-to-day work and how Collabora works, discuss compensation and benefits
- Offer (1 week of final interview)
Total timeline: 3-4 weeks from application to offer

Collabora's Commitment
We're committed to building a diverse team and inclusive environment. We encourage applications from people under-represented in tech.
We evaluate candidates based on skills and contributions, not pedigree. If you're unsure whether you qualify, apply anyway—imposter syndrome is real and you might be exactly who we're looking for.
We recognise that the combination of deep kernel expertise and consulting skills is rare. If you have strong kernel development experience and are newer to the consulting side of the role, or vice versa, we want to hear from you. We can develop one if the other is solid.
