Job summary

E-Space in Saratoga, CA is seeking a Linux Kernel Developer to design, develop, and debug kernel code for our space-grade hardware. You will work with embedded software engineers, systems engineers, and hardware teams to ensure our platforms are stable, performant, and production-ready.

The role requires 5+ years in C and Linux kernel internals, experience with device drivers, Yocto/Buildroot, and hands-on bring-up with JTAG.

Qualifications

• 5+ years of experience developing in C with Linux kernel internals.
• Proven experience writing and debugging Linux device drivers and kernel modules.
• Experience with embedded Linux build systems (Yocto, Buildroot, or similar).
• Comfortable working with hardware during bring-up and debugging with JTAG or logic analyzers.
• Strong debugging using tools such as gdb, ftrace, perf, kgdb, or crash dump analysis.

Responsibilities

• Design, develop, and maintain Linux kernel code, including drivers, subsystems, and kernel modules.
• Port, configure, and optimize the Linux kernel for custom hardware platforms.
• Write and maintain device drivers for a range of interfaces (e.g., I2C, SPI, UART, USB, PCIe, Ethernet).
• Debug and resolve kernel panics, race conditions, memory issues, and other low-level system failures.
• Profile and optimize kernel and driver performance, including boot time, latency, and power consumption.
• Work with bootloaders (e.g., U-Boot) and board bring-up for new hardware revisions.
• Collaborate with hardware engineers during board bring-up and hardware/software integration.
• Upstream patches where appropriate, and track relevant upstream kernel changes and CVEs.
• Contribute to kernel configuration, build systems (e.g., Yocto, Buildroot), and CI integration.
• Document kernel architecture decisions, driver interfaces, and debugging procedures in a way thats practical and reusable
