Job description

Do you want to shape the engineering direction behind technology that drives the energy sector?

At Mind Energy, technology enables how we trade, optimise and evolve in a fast-moving energy market. As our Senior Software Engineer, you take a central role in building and evolving the digital backbone that supports critical business decisions every day.

You combine strong technical depth with architectural thinking and a hands‑on engineering mindset. Working closely with experienced colleagues across development and business, you help shape scalable systems, influence technical direction and raise the engineering bar around you.

DIVE INTO WHAT YOUR DAY-TO-DAY TASKS WILL BE

In this role, you take an active par t in shaping the technical direction of our digital landscape. You modernise existing systems, build new solutions and turn complexity into reliable, scalable software that supports both trading and long-term growth.

Your mission is to:

• Design, develop, test and deploy stable, scalable and secure software solutions
• Take architectural responsibility and influence the long-term direction of our digital platform
• Build resilient services and systems designed for performance, scalability and maintainability
• Drive technical improvements and challenge existing solutions with a strong engineering mindset
• Collaborate closely across teams while supporting knowledge sharing, sparring and engineering quality

JOIN A TEAM OF MINDFUL ACHIEVERS

You’ll join an autonomous, cross‑functional team with end‑to‑end ownership of its domain, spanning design, architecture, implementation and operations.

Together, you work closely with business stakeholders to translate complex needs into robust, scalable and secure solutions that create real value for our customers.

At Mind Energy, we value both independence and collaboration.

Your work ranges from refining existing systems to shaping entirely new solutions, always with a clear sense of ownership and responsibility. You approach complexity with curiosity and turn challenges into solutions built to last.

LET’S SWITCH THE FOCUS TO YOU

You are an experienced engineer who thrives with ownership, technical responsibility and the opportunity to influence how solutions are designed and built. You bring strong engineering fundamentals, architectural understanding and the confidence to challenge decisions when better solutions exist.

We imagine that you bring:

• Extensive experience building scalable systems in C# and .NET, with a consistent approach to clean, maintainable code and modern design patterns
• Hands‑on experience designing and building resilient, event‑driven services in distributed and cloud‑native environments
• Experience balancing scalability, reliability and maintainability when designing architectures for complex production systems
• Experience taking technical ownership and helping shape engineering direction through architectural decisions, sparring and pragmatic technical leadership

If you also have insight into the energy sector, it will be an advantage, but it is not required.

We encourage candidates from all backgrounds and identities to apply, as we believe that a diverse team leads to innovation and success.

Please note that this role requires working from our office location Aarhus N.

WE MIGHT BE BIASED, BUT IT IS QUITE AWESOME HERE

People here care about doing things well and creating a place people genuinely enjoy being part of. We like to hack the everyday, from breakfast and lunch made in‑house with organic ingredients to in‑house massage, something in the freezer when the day runs late and the occasional “Just Because” surprise. You also get five Switch Days, equal to a seventh holiday week, giving you extra flexibility and room to recharge throughout the year.

Through Mind Club, people come together around everything from padel and Football Shirt Fridays to clay pigeon shooting and Christmas afternoons with your family and Santa. And with Mind Academy, you grow alongside sharp and curious colleagues who challenge ideas, share knowledge and help each other level up. These are just some of the things that make us special. It’s easier to experience in person.

We’re mindful achievers. It shapes how we work, think and grow together, while recognising that well‑being, care and integrity matter just as much as the results we create. This is a place to focus, grow and achieve more.
