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.

* Knowledge of FPGA or other low-level hardware programming.

* Experience with CI/CD pipelines and automated build/test tools.
