Just your insights and experience. Sounds exciting? Keep reading.

At DEIF A/S, we develop advanced control solutions that keep power stable and efficient – whether from wind, solar, or traditional sources. With more than 650 dedicated employees worldwide , we push boundaries, set new standards in energy efficiency and conversion, and work towards becoming the market leader in intelligent energy control. Together, we create solutions that Improve Tomorrow.

About the job

As an Embedded Software Developer at DEIF, you’ll help shape tomorrow’s energy solutions. Our products control and switch between various energy sources – including solar, wind, diesel, and batteries – for more efficient and reliable power production. Most R&D, manufacturing, and testing takes place at our headquarters in Skive, giving us a unique setup that fosters close collaboration and rapid innovation.

You’ll join a team of 20 skilled colleagues developing embedded application software for our Linux-based multi-core controller platform . You’ll be responsible for developing the software that determines how our products respond to real-world conditions – like when batteries charge or discharge, how generators operate, and how new features such as DC systems are added to our platform.

“DEIF offers an open platform that allows customers to develop and run their own applications on our robust controllers. As a Software Developer, you will be part of the full development process – from idea to system integration”, explains Department Manager, Simon Appelt.

Working tasks and responsibilities

• Develop embedded application software in C++ for DEIF’s Linux-based controller platform
• Write unit tests in C++ and contribute to automated validation using CI/CD frameworks.
• Collaborate closely with hardware and software teams to ensure smooth system integration.
• Participate in Agile development processes and contribute to continuous improvement of our software platform

The Software Team works in Agile sprints of 2 weeks, allowing for frequent feature delivery and continuous feedback. You’ll collaborate closely with your team, product specialists, and other stakeholders, ensuring high-quality solutions while learning from colleagues with diverse skills and backgrounds.

What we’re looking for

We’re looking for a passionate engineer who enjoys solving complex technical challenges. You thrive in a collaborative environment where progress is driven by shared ideas, diverse skills, and teamwork.

You have experience with embedded software development in C/C++ , gained either during your studies or from your early professional career. Knowledge of ANSI C, VCS, object-oriented programming or CI/CD tools is a plus.

How to apply

Forget the traditional CV and application. To apply, simply answer the 4 job-specific questions below!

That’s it – and remember to leave out personal details such as name, age, or ethnicity, nationality, etc.

1 - Battery Control Logic in Hybrid Systems

Think back to a time when you worked with battery systems or studied energy control logic. Based on your experience, what specific factors did you consider ensuring both efficiency and safety in charging/discharging? If you haven’t worked directly with batteries, describe how you would approach structuring the logic, and explain your reasoning with a real-world analogy or example.

2 - Ensuring Stable Generator Output

Describe a situation where you had to manage or simulate interactions between multiple energy sources. What specific software strategies would you use to ensure stable generator output, and how would you test your solution? Share any lessons learned or trade-offs you’d consider.

3 - Adding Business Logic to Controller Application

Imagine you’re tasked with integrating DC system logic into an existing controller application. Based on your experience or understanding of embedded systems, what are the key software considerations you’d prioritise? Describe how you would avoid introducing regressions or performance issues and mention any tools or practices you’d use.

4 - Handling Software Project Challenges

Share a specific example of a software project where something didn’t go as planned. What was your role, what went wrong, and how did you adapt? What would you do differently today, and how has that experience shaped your approach to problem-solving?
