Senior Backend Engineer
At Lunar, we’re all about taking on challenges together and creating something meaningful. We’re building payment solutions that matter, and we need a Senior Backend Engineer who’s ready to jump in, collaborate, and help us make it happen. Here, your work will have a direct impact, and your ideas will be valued.
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 Senior Backend Engineer to power seamless, reliable, and innovative core banking solutions for all Lunar's customers so that we can strengthen our position as the go-to bank in the Nordics. As our new Senior Backend Engineer, you will be part of our Core Banking business area, reporting to Girish Premchandran. This area currently comprises a diverse group of amazing individuals working in Aarhus who are focused on enabling Lunar's core banking business by providing clearing and settlement systems across the Nordics and handling all card transactions within the broader Technology function, led by Rolf Njor Jensen.
What will you do?
Develop and maintain our core banking systems, ensuring high performance, reliability, and security.
Work with distributed systems and event-driven architecture to scale our payment infrastructure.
Demonstrate end-to-end ownership of projects, managing dependencies across various teams to deliver high-quality solutions on time.
Embrace and uphold engineering standards, contributing to a culture of continuous improvement and technical excellence.
Collaborate with a strong and experienced team, using the Scrum framework to plan, execute, and deliver impactful projects.
