Backend Engineer
We're not just building a bank. We're automating a financial revolution. Do you want to help create it? đź’«
At Lunar we are democratizing the power of money and changing the way we all bank, pay, and invest. Since starting in Aarhus in 2015, we've grown rapidly and are now a major player in the Nordics, with offices in Copenhagen, Aarhus and Stockholm 🚀
So who are we? Are we a tech company or a bank? Well, we're both, breaking free from the usual categories. Here, tech isn't just a cool add-on; it's the core of how we do things. With our own banking license, we go head-to-head with traditional banks. What sets us apart is the mix of tech and financial services, giving us the power to shake up a dusty industry that's ready for a change.
As we continue our journey to becoming the best everyday bank in the Nordics, we are looking for a Backend Engineer to build and maintain our backend services for banking automation, directly contributing to our mission of streamlining and transforming internal operations with intelligent automation and innovative solutions. By joining us, you'll enable efficiency, scalability, and exceptional outcomes across all functions of Lunar’s banking operations. As our new Backend Engineer, you will be located in Copenhagen and report to Søren Thiel Berg, Head of Tech. The team is focused on building software within the banking automation domain within the broader Technology function, led by our CTO Kåre Kjelstrøm.
What will you do?
You’ll take the reins in developing and maintaining our backend services, making sure our users have a smooth and efficient experience every time.
Focus on automating Lunar's operations and building scalable solutions to prepare for our future growth.
Building, optimizing, and fine-tuning products, services, and features will be your playground – all to support the essential functions that drive our business.
You’ll integrate with third-party systems, pushing the boundaries of what our platform can do.
Collaborating across teams will be key as you help us level up and bring fresh ideas to life, improving and innovating on everything we do.
Your backend expertise will be the fuel for driving real impact across different areas of the business.
And when it comes to AI? You’ll be exploring the cutting edge, using AI to supercharge both new and existing products and features, keeping us ahead of the game.
