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)
