Embedded Linux Engineer

Circuit32 Recruitment Solutions Ltd; Gloucester; Remote; GBP 54,000 - 90,000; Full time

Job summary

Circuit32 Recruitment Solutions Ltd is seeking an Embedded Linux Engineer to join a small engineering team. You’ll work at kernel level, bringing up hardware and writing drivers that make it work; the role is remote with occasional travel to Cheltenham.

You’ll tackle Linux kernel drivers, board bring-up, U-Boot, device tree, BSP work, and performance optimisations on resource‑constrained platforms, collaborating with hardware engineers.

Qualifications

• Commercial experience of Linux kernel development on embedded targets.
• Track record of writing and debugging device drivers (I2C, SPI, UART, GPIO, DMA, platform drivers).
• Strong C with solid grasp of kernel internals: memory management, interrupts, concurrency.
• Hands-on board bring-up and device tree experience on ARM platforms.
• Comfortable with Yocto or Buildroot.

Responsibilities

• Developing and maintaining Linux kernel drivers for custom hardware and software.
• Board bring-up, including bootloader (U-Boot), device tree and BSP work.
• Debugging low-level issues across the hardware/software boundary.
• Optimising performance, power and boot time on resource-constrained platforms.
• Working closely with hardware engineers on new designs.

Job description

We're looking for an Embedded Software Engineer with genuinely deep Embedded Linux experience to join a small engineering team. This isn't a build-and-configure role: you'll be working down at the kernel level, bringing up hardware and writing the drivers that make it work.

ROLE: Embedded Linux Engineer

LOCATION: REMOTE Occasional travel to Cheltenham

RATE: up to 65ph (outside IR35)

DURATION: 6 months

What you'll be doing

• Developing and maintaining Linux kernel drivers for custom hardware and software
• Board bring-up, including bootloader (U-Boot), device tree and BSP work
• Debugging low-level issues across the hardware/software boundary
• Optimising performance, power and boot time on resource-constrained platforms
• Working closely with hardware engineers on new designs

Essential skills for the Embedded Linux Software Engineer

• Commercial experience of Linux kernel development, not just user-space on an embedded target
• A track record of writing and debugging device drivers (e.g. I2C, SPI, UART, GPIO, DMA, platform drivers)
• Strong C, with a solid grasp of kernel internals: memory management, interrupts, concurrency
• Hands-on board bring-up and device tree experience on ARM platforms
• Comfortable with Yocto or Buildroot

You must be willing to travel to the customer site in Cheltenham, Gloucestershire at least once per month and more frequently if needed.
