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 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 the Lending team out of Stockholm, reporting to Kasper Ernerot, General Manager -
Lending, working to build Lunar's lending products from the ground up — for over 1 million consumer users today.
We're a team of 5 engineers building a brand new product area. There's a foundation in place, but most of the big architecture
decisions are still ahead of us — and the ones you make in your first months will still be load-bearing years from now. High
ownership, real impact, and a team that helps each other get there.
What will you do?
- Design and build the distributed, event-driven services behind our lending or overdraft products - you'll join one of the two
teams - owning them from architecture through to production.
- Take end-to-end ownership of core lending domains, making the trade-off calls on reliability, performance and speed as we scale
from launch to a full product portfolio.
- Lead technical discussions on system design, and raise the bar around you through code review, mentoring and clear technical
direction.
- Partner 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?
Solid experience as a backend engineer, with a proven track record of designing and delivering complex systems at scale.
- Strong experience with event-driven architecture and distributed systems, and a clear grasp of the trade-offs that come with
them.
- Experience with cloud technologies. Go is a significant advantage, though not a hard requirement — we'll help you get up to
speed.
- A doer. You get things done, you work with a high degree of autonomy, and you're happy operating without a well-worn path in
front of you.
- Bonus points for experience with agentic engineering or AI-driven SDLC, and especially for experience in lending, credit, or
financial services — an area we're actively building out.
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.
Access to some of the latest AI tools and models. We take serious actions to keep ourselves on the top of the wave!
- Pension, health insurance, and enhanced parental leave. From your financial future to your family moments. We've got you
covered.
