• Strong understanding of Linux internals, including:


• Processes and threads


• Scheduling


• Memory management


• Inter-process communication (IPC)


• Signals


• File systems


• Experience debugging Linux applications using tools such as GDB


• Comfortable working within a Linux command-line environment


• Experience using Git

Desirable Skills

• Embedded ARM platforms


• Cross-compilation toolchains


• Yocto or Buildroot


• Device communication (SPI, I²C, UART, CAN or USB)


• Network programming (TCP/IP, sockets)


• CMake


• Python or Bash scripting


• Docker and CI/CD pipelines

About You

You'll be someone who:

• Enjoys solving complex technical problems


• Has a genuine passion for embedded software development


• Thrives in a collaborative engineering environment


• Takes pride in writing efficient, reliable and maintainable code


• Is curious, proactive and keen to continually improve

What's on Offer

• Competitive salary


• Hybrid working
