Senior Backend Engineer - Lending
Confirmed on the employer's own hiring board on Nov 9, 2026. First seen by Alion on Sep 7, 2026.
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 financial life 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 a million registered users 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 the Lending team based in Stockholm, reporting to Kasper Ernerot, working to build Lunar's lending products from the ground up.
Lending is a brand new product area for us, and most of the big architecture decisions are still ahead. The choices you make in your first months will shape our lending portfolio for years. You'll be one of five engineers building lending and overdraft, with real ownership, a team that helps each other get there, and a genuine chance to leave your mark on how Lunar lends money.
What will you do?
Design and build the distributed, event-driven services behind our lending or overdraft products, owning them from architecture through to production.
Own core lending domains end to end, making the trade-off calls on reliability, performance and speed as we grow from launch to a full product portfolio.
Lead technical discussions on system design, and raise the quality bar through code review, mentoring and clear technical direction.
Work with product, design and risk to ship lending experiences customers actually feel, in a regulated space where getting it right matters.
Explore where AI can make our lending products smarter, from decisioning to the everyday customer experience.
What are we looking for in you?
You've built or run services that handle credit, loans or repayments, such as decisioning, loan servicing or interest calculation.
You've designed and delivered complex backend systems at scale that real customers depend on.
You know event-driven architecture and distributed systems well, and understand the trade-offs that come with them.
You have experience with cloud technologies. Go is a significant advantage, though not a requirement, and we'll help you get up to speed.
You get things done, work with a high degree of autonomy, and are comfortable without a well-worn path in front of you.
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.
A well-equipped workspace. You'll have a modern computer and a comfortable desk setup. We want you to have the tools you need to do your best work.
Pension, health insurance, and enhanced parental leave. From your financial future to your family moments. We've got you covered.
