Zephyr Embedded Software Engineer

In this role you will drive hands-on Zephyr-based embedded software development for high-performance RF and communications products. You will work closely with RF, FPGA, and hardware teams to deliver solutions from prototype to volume manufacture. The position spans bare-metal, embedded Linux, and secure communications, offering impact across the full development lifecycle in a Cambridge, hybrid setting. You will tackle integration, debugging, and optimization on resource-constrained systems, shaping outcomes for telecom, space, and defence applications. This opportunity combines technical depth with cross-functional collaboration in a mission-driven tech environment.

• Develop and maintain Zephyr-based embedded software and firmware
• Collaborate with RF, FPGA and hardware engineers across the full development lifecycle
• Prototype development, hardware/software integration, and debugging
• Work with embedded communication interfaces such as CAN, SPI, I2C, UART, RS422
• Troubleshoot using oscilloscopes, logic analyzers, and related tools
• Evaluate and contribute to embedded Linux, Yocto, bare-metal firmware, or RTOS options
• Support secure communications concepts and secure firmware update discussions (advantageous)

• Strong experience with Zephyr for low-level embedded software and firmware
• Excellent C/C++ programming skills with optimization for constrained systems
• Prototype board bring-up and hardware/software integration and debugging
• Experience with CAN, SPI, I2C, UART, RS422 interfaces
• Robust debugging skills using oscilloscopes and logic analyzers
• Experience with embedded Linux, Yocto, bare-metal firmware or RTOS platforms (beneficial)
• Knowledge of secure communications, authentication, encryption or secure firmware updates (advantageous)

• collaboration with cross-functional teams
• strong problem-solving mindset
• attention to detail
• Zephyr-based embedded software
• C/C++ programming
• prototype board bring-up
