Job Title: Embedded Software Design Engineer
Location: Cardiff area
Employment Type: Permanent, full-time
Visa sponsorship: Not available (UK rights to work required)
We’re on the lookout for an Embedded Software/Firmware Engineer who loves working with embedded systems and enjoys getting hands-on with both code and hardware.
This is a great opportunity to work on exciting, real-world products that demand smart, reliable software. You’ll be involved in the whole journey — from brainstorming ideas and designing solutions to testing, tweaking, and launching. If you enjoy solving tricky problems and seeing your work make a real impact, this could be a great fit.
What You’ll Be Doing
* Developing and improving embedded software and firmware for a variety of processors and microcontrollers.
* Building and fine-tuning low-level drivers and communication protocols to keep everything running smoothly.
* Writing clean, efficient C/C++ code that performs well in the real world.
* Getting involved in early design discussions to help shape system architecture and technical decisions.
* Working closely with hardware to figure out (and fix!) integration challenges.
* Helping create secure and reliable firmware update systems.
* Taking part in testing — from quick checks to full system validation — to make sure everything works as it should.
* Keeping documentation clear, simple, and useful.
* Collaborating with teams across hardware, systems, QA, and product to bring ideas to life.
What We’re Looking For
Essential:
* A degree or solid experience in Software Engineering, Computer Science, Electronics, or something similar.
* Hands-on experience developing software and firmware for embedded systems.
* Strong skills in C and C++, with a focus on writing reliable and maintainable code.
* Experience with RTOS or bare-metal development.
* A good understanding of microcontrollers and protocols like I2C, SPI, UART, and CAN.
* Comfortable using tools like oscilloscopes and logic analysers.
* Familiar with version control (e.g., Git) and Agile workflows.
* Enjoys problem-solving and isn’t afraid to get stuck into tricky debugging.
* Communicates well and works well with others.
Nice to Have:
* Experience working in regulated or safety-critical environments (e.g., DO-178C, ISO 26262, IEC 61508).
* Knowledge of FPGA or other low-level hardware programming.
* Experience with CI/CD pipelines and automated build/test tools.
