Firmware Engineer

Embedded Firmware Engineer (STM32) – Contract – South Wales (Onsite) I’m working with a medical device company in South Wales developing new hardware products, and they’re looking for an embedded firmware engineer to support development on two newly designed boards. This is a hands-on role, working close to hardware — not a pure software position. What you’ll be doing: Developing firmware on STM32 microcontrollers Working on two new boards: One focused on analog signal acquisition (ADC → UART data flow) One focused on control systems, managing I/O and SPI communication with peripheral boards Collaborating with hardware engineers and working from existing schematics/PCB designs Taking ownership of getting the boards fully functional and integrated ✅ What they’re looking for: Strong experience with embedded C / firmware development Hands-on experience with STM32 Experience working with communication protocols such as SPI and UART Comfortable working close to hardware (schematics, PCB understanding) Able to work onsite in South Wales 3 days per week ➕ Nice to have: Experience working with FPGAs Exposure to ADC / signal acquisition systems Any experience in medical devices or regulated environments Details: Initial 3-month contract (likely extension) Onsite requirement: 3 days per week (South Wales) Working alongside an existing firmware team (with internal STM32 knowledge) If this sounds like something you’d be interested in, or you’d like more details, feel free to drop me a message.
