Descripción del empleo

Fully Remote | Linux Kernel Engineer | 6.16 Upstreaming Opportunity | 2+ Year Engagement | High Pay

Join a Leading Semiconductor Innovator at the Forefront of Linux Kernel 6.16 Development

We’re looking for elite Linux Kernel Engineers to contribute to a next-generation custom AI silicon platform in active development by a globally recognized semiconductor leader . This fully-remote role (work from anywhere in Europe ) offers a rare opportunity to work at the bleeding edge of Linux kernel internals , contributing to a platform designed for AI / ML acceleration at the silicon level (previous AI / ML is not required) .

The Role :

You’ll be embedded in a high-caliber engineering team working on a custom Linux Kernel 6.16 fork , developed to tightly integrate with a novel AI-focused SoC. Your work will span deep kernel internals and involve :

• Low-level kernel modification and customization to support proprietary compute fabrics, memory subsystems, and I / O models.
• Backporting critical features and security patches across kernel branches.
• Collaborating on upstreaming efforts for select modules and drivers.
• Working on real-time performance tuning, scheduler modifications, and DMA pipeline integration.
• Close interaction with hardware engineers to bring up, test, and validate new board designs and chip revisions.

We’re Looking For :

Proven experience with Linux kernel development , ideally on recent kernel branches (5.x–6.x series).

Solid expertise in kernel module development , memory management, interrupt handling, and device driver architecture .

Strong knowledge of backporting techniques and tools.

Experience with upstream contribution workflows (patch submission, mailing lists, kernel.org practices).

Prior exposure to custom SoC enablement , preferably in AI / ML , DSPs, or edge compute platforms.

Comfort working with git , make, and low-level debugging tools (kgdb, perf, ftrace, etc.).

Fluent written and verbal communication in English.

Bonus Experience :

Knowledge of Yocto , Buildroot , or other embedded Linux build systems.

Prior work on AI accelerators , RISC-V , or custom compute architectures.

Contributions to the mainline Linux kernel .

Location :

Remote-first – work from anywhere in Europe

Collaboration across EU time zones

What’s in It for You :

Join a multi-year, high-impact silicon development project with a world-class team

Deeply technical, kernel-first role with wide architectural influence

Work on real hardware , real performance challenges, and a real upstream story

Flexible working hours, excellent technical autonomy, and competitive compensation (way over 100k per year equivalent)

If you're passionate about building and bending the Linux kernel to serve next-gen compute, we want to hear from you .

Apply now and bring your kernel expertise to one of the most exciting hardware / software co-design projects in Europe today.
