Job description

Banking hasn't changed much in decades. We're changing that. One product at a time.

Lunar is a Nordic challenger bank building the future of banking, with AI at the core. Our engineers, designers, and product people work on problems that actually matter. Making money simpler, smarter, and more rewarding for millions of people across the Nordics.

Fully licensed and founded in 2015, with offices in Copenhagen, Aarhus and Stockholm.

We move fast, we build with purpose, and we're just getting started.

As our new Senior Backend Engineer you'll join one of our Money Core squads based in Aarhus, reporting to Girish Premchandran, Director of Technology - Core Banking, working to build out our domestic payments universe and power banking at Lunar.

What will you do?

• Take ownership of critical banking domains, developing and maintaining the systems that keep our banking products running on a solid, reliable foundation


• Integrate with external partners to extend and strengthen what our platform can do


• Keep our systems highly available and resilient, while looking for new ways to make the customer experience better


• Explore how AI can enhance the banking experience for our customers, from first idea to production


• Share what you know and help the people around you grow, while staying open to learning from them too

What are we looking for in you?

• 4+ years of professional experience as a backend engineer, with a solid background in distributed systems and event-driven architecture


• A collaborative team player who enjoys sharing knowledge and helping others succeed


• You communicate clearly and work well within a diverse, cross-functional team


• Experience with Golang is a big plus, though not a requirement — we'll help you get up to speed


• Financial or trading experience is a bonus, not a must

What you get

• 4 days in the office. We're a team that builds together, thinks together, and moves together. Showing up is part of how we work.


• State of the art equipment. The newest computer, monitor, mouse, and keyboard. We want you to do your best work without anything slowing you down.


• Pension, health insurance, and enhanced parental leave. From your financial future to your family moments. We've got you covered.

Depending on the regulations in the country where you will be employed, we will ask to see or obtain information about your criminal record.

Please note that our employment is conditional upon you not being registered in RKI (Ribers Kredit Information).

We welcome applications from candidates of all backgrounds. If you need any adjustments during the recruitment process, please let us know.
