We're a profitable Swedish fintech that helps people refinance expensive consumer loans at better rates. Small team, regulated industry, which sounds like a recipe for slow, cautious engineering. It’s the opposite. The regulation sets the floor, not the ceiling. Above that floor, we experiment, ship, break, learn, and ship again. We're building real-time credit decisions using ML models on GKE, Go and Python on the decision layer, TypeScript/Node.js on the API, React on the frontend, BigQuery and dbt for data. Interesting stack, interesting problems, and because we're small, you're close to all of it. Our co-founder Sven is back leading eng and hiring directly. No recruiter chain, no committee. Short feedback loops. Real ownership. No one to hide behind.
