At Klarna, we’re building an everyday finance network, helping over 120 million consumers across 26 countries save time and money, and worry less about their finances. Working here means taking on problems most companies never get to solve, and being hands-on enough that the interesting part of the work lands with you, not someone else — you’ll build with AI, not watch it happen.

Being an engineer at Klarna means building and owning the systems that move money for millions of people — and that responsibility doesn’t end when those systems ship. Your team and your focus can also change as the business changes, and the domain you join may look different in a year. Either way, this stays a hands-on role: you’re still writing code, still making architecture calls,



still in the codebase, and your influence comes from the quality of that work and the engineers you work most closely with.

You’ve built something we haven’t. You’ve gone deep somewhere we haven’t been yet. what they don’t have is your specific experience, and that’s exactly the gap we’re hiring into.

Think past your own contribution: how it fits the wider architecture, where failures propagate, what breaks first under load, and who feels it downstream.
