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.
