The posting

If you’re an experienced embedded software engineer who enjoys working where SOFTWARE, POWER ELECTRONICS, MOTOR TECHNOLOGY and CONTROL ENGINEERING meet, this could be the job for you.

OJ Electronics – a Danish producer of HVAC drives, AHU controllers, and thermostats for electric floor heating – is looking for an intermediate/senior-level embedded software engineer to join our Drives software team in Sønderborg, Denmark.

  • Contribute to system design and architecture
  • Build robust simulation models to validate control concepts early in the development cycle
  • Take responsibility for documentation
  • Participate in testing and validation
  • Sometimes help customers directly with troubleshooting and issue resolution

Broad-based collaboration

As part of our diverse R&D team, you’ll work alongside hardware engineers and other specialists, contributing to the entire product lifecycle and getting involved in challenges ranging from communication and automation protocols to motor technologies and control-system engineering.

You’ll also have the satisfaction of seeing your own code running in thousands of products – helping improve everyday comfort and energy efficiency for users around the world.

Must-have qualifications

  • Experience with Git, Git Flow and CI/CD
  • Knowledge of communication interfaces such as UART, I2C and SPI
  • Practical laboratory testing and validation experience
  • Structured problem-solving and debugging skills
  • Clear and concise technical communication in English
  • A team-oriented mindset and experience with agile collaboration

Experience with:

  • Modbus or BACnet
