Klarna, briefly 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.

What you'll do Make sound, defensible technical decisions, and be able to say clearly what you decided against and why. Think past your own contribution: how it fits the wider architecture, where failures propagate, what breaks first under load, and who feels it downstream. Tie technical choices to business outcomes and size the solution to the problem's actual value - including when the right answer is something small. Design for the constraints that come with being a regulated bank - reliability, auditability, controls - and treat them as part of the engineering problem rather than an obstacle to it. Mentor engineers and raise the technical bar across teams. You act as a multiplier and elevate the peop
