Junior Embedded Software Engineer – STM32 / ARM / C# / Avalonia
Location: Littleport, Ely, Cambridgeshire
Salary: £30,000–£40,000 per annum
Employment Type: Full-time
About the Role
We are looking for a motivated and enthusiastic Junior Embedded Software Engineer to join our growing engineering team. This is an exciting opportunity for an early-career engineer to develop their skills across both embedded firmware and desktop application development.
You will contribute to the design, development, testing, and support of software for products based around STM32 ARM Cortex-M microcontrollers, while also developing PC-based applications and tools using C# and Avalonia UI.
Working closely with experienced firmware, software, and hardware engineers, you will gain hands-on experience across the full software development lifecycle, from low-level embedded firmware through to user-facing applications.
Key Responsibilities
- Develop and maintain embedded firmware for STM32 ARM Cortex-M based products.
- Write clean, efficient, and maintainable code primarily in C.
- Develop Windows and cross-platform desktop applications using C# and Avalonia UI.
- Create software tools and user interfaces for configuring, controlling, testing, and monitoring embedded systems.
- Configure and use STM32 peripherals, including GPIO, timers, ADC, USB, SPI, and I²C.
- Develop and maintain communication interfaces between embedded devices and PC applications.
- Assist with firmware and application debugging, testing, and troubleshooting.
- Use tools such as debuggers, oscilloscopes, logic analysers, and multimeters to investigate hardware and software issues.
- Support the development of firmware drivers and low-level software.
- Work with version control systems such as Git.
- Contribute to code reviews, technical documentation, and software development processes.
- Collaborate with hardware, electronics, and systems engineers throughout the product development lifecycle.
- Help develop automated testing and diagnostic tools to improve product reliability and development efficiency.
