This is a multi-year , fully remote (EU) role embedded in a technically elite kernel team , focused on custom SoC bring-up , device driver development , and upstream/backport contributions to the Linux 6.x kernel series. You’ll be doing meaningful upstream Linux work , not vendor forks or throwaway code — this is a rare opportunity to shape how Linux interacts with new hardware at the architecture level . Low‑level kernel development : scheduler hooks, memory subsystems, DMA, interrupt controllers, custom bus interfaces Device driver development and optimization for new IP blocks across memory, I/O, interconnect, and peripheral subsystems Upstreaming drivers and kernel changes in collaboration with maintainers and internal teams Backporting select features and security patches across active kernel lines Real silicon bring‑up : working with FPGA prototypes, dev boards, and production silicon during validation and test Cross‑functional collaboration with silicon, board design, and firmware teams — deep hardware/software co‑design What You Bring Strong experience with Linux kernel development (5.x–6.x series preferred) Deep understanding of kernel internals , including memory management, page tables, DMA APIs, interrupt handling, and scheduling Expertise in writing and debugging kernel modules and device drivers Solid knowledge of driver and subsystem integration (e.g. I2C, SPI, PCIe, MMIO, interconnect) Experience contributing to or working with upstream Linux kernel practices : patch submission, review cycles, kernel.org, etc. Comfortable with backporting workflows , git, quilt, or other patch stack management tools Fluent with low‑level debug and trace tools : kgdb, perf, ftrace, crash, dmesg, etc. Contributions to mainline Linux kernel or driver subsystems Experience with Yocto, Buildroot , or embedded Linux platforms Background in board bring‑up or SoC/CPU architecture enablement Familiarity with custom interconnects, MMUs/IOMMUs, or low‑level bus protocols Experience supporting productized Linux platforms in silicon or hardware programs Upstream‑first mentality — work on code that lives beyond the project Architectural influence : you won’t just implement — you’ll help shape system‑level design Work on real hardware , not just emulation or sim — early silicon, board prototypes, and post‑silicon validation Highly collaborative open source and internal engineering culture Flexible hours, fully remote within the EU, and excellent compensation (well above €100k equivalent) Work with engineers who care about correctness, maintainability, and long‑term impact Seniority level Mid‑Senior level Employment type Contract Apply now
