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 a team based in Copenhagen, reporting to Eugene, working to automate manual and repetitive tasks in Financial Crime Control at scale, across our broader Technology function.

• Design and deliver complex distributed systems that improve Financial Crime Control efficiency, anticipating technical risks and dependencies before they become blockers.
• Guide teams in the responsible and effective use of AI tooling as it becomes a bigger part of our stack.
• Lead technical discussions on system design and implementation, and mentor other engineers — a bigger part of the role as you grow into its senior scope.
• Partner with teams across the organization to help them build and integrate new solutions, working across domains to solve data aggregation and integration challenges, and drive projects with minimal support.
• Work with a high degree of autonomy in an agile environment, and evaluate team processes to identify and implement high-impact improvements.

What are we looking for in you?

• Minimum of 3 years of backend experience, with a proven track record of designing and delivering complex systems at scale.
• Expertise in event-driven architecture and distributed systems, balancing trade-offs to ensure system reliability and performance.
• Experience with cloud technologies.
• Experience with Go is a significant advantage.
• A strong interest in AI and familiarity with solutions like OpenAI.
• Excellent collaboration and communication skills, with the ability to work effectively across different teams and domains.

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.
