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.
