Job Title: Embedded Software Design Engineer Location: Cardiff area Employment Type: Permanent, full-time Visa sponsorship: Not available (UK rights to work required) Location: Cardiff Employment Type: Full-Time (Early Finish Fridays!) About the Role 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.
