Senior — typically 5+ years developing architecture-level code or device drivers for multiprocessor, multithreaded open-source kernels (Linux/BSD) with upstream involvement.

Responsibilities

Deliver, integrate and upstream system software and collaborate with hardware and architecture teams to define and verify platform features.

• Design, implement, upstream and release Linux kernel subsystems and device drivers.
• Develop and maintain OpenSBI, U-Boot and Yocto/OpenEmbedded platform code.
• Work with architecture and hardware teams to review and refine hardware/software interfaces (CPUs, interconnects, firewalls, IOMMUs).
• Debug complex multicore systems and support bring-up using tools such as GDB, JTAG and OpenOCD.
• Participate in upstream open-source development and code review processes.

Requirements

Core technical skills and experience required for the role.

• Expert knowledge of PCIe, Ethernet and CXL interfaces.
• 5+ years developing architecture-level code or device drivers in C for Linux or BSD with upstream contributions.
• Proven upstream development experience on Linux or similar high-level OS.
• Experience debugging complex multicore systems; familiarity with GDB, JTAG and OpenOCD.
• Experience with git, Makefile, GNU toolchain and shell scripting.
• Experience with device drivers, virtualization and IOMMUs.
• Strong communication and collaboration skills; experience working with hardware architecture and engineering teams.
• Desired: experience with ACPI, UEFI and edk2 and familiarity with data center platforms.
