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.

• 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.

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.
