Senior Embedded Software Engineer
Filtronic is looking for a Senior Embedded Software Engineer to join our growing software engineering team in Cambridge.
You will play a key role in the design, development, and integration of embedded software and firmware for advanced RF and communications products, working across the full product lifecycle from concept and development through to volume manufacture.
The role has a strong focus on Zephyr-based embedded development, with opportunities to work across embedded Linux, Yocto, bare-metal firmware, networking, and secure communications.
You will work closely with experienced RF, FPGA, hardware, and systems engineers, contributing to products supporting applications across telecommunications, space, high-altitude platforms, and defence.
