Job description

Anyfin is building the next generation of consumer finance. We’re profitable, scaling quickly, and now operating with a banking license which opens up a lot of technical complexity. We’re looking for a senior fullstack engineer who enjoys moving fast, taking real ownership, and building things that actually have an impact. We work from the office because we think it makes us better, especially at this stage. If that sounds like your kind of environment, keep reading. Because honestly, it’s not a role for everyone.

What You’ll Do

• Build and ship features across backend, web and mobile.
• Own projects from idea to production (and beyond).
• Make product and technical decisions, not just implement tasks.
• Build systems that scale with real users and real money.
• Work closely with product and design, in person, every week.

Our main stack is TypeScript, Node.js, React, React Native.

How We Think About Building

We’re pragmatic. We like speed, but we also care about building things that last. AI isn’t a side tool here. It’s embedded in how we work helping engineers move faster, reduce friction and focus on solving meaningful problems. We’re looking for engineers who are curious about that shift and want to be part of it, rather than people who feel like good engineering means doing everything the hard way. No ego. Just good judgment and high output.

You’ll Thrive Here If You…

• Have solid fullstack experience.
• Take responsibility naturally and don’t wait to be told what to do.
• Enjoy messy problems and figuring things out as you go.
• Like being in an ambitious, collaborative team in the office.
• Want to build, not just maintain.

You’re Comfortable With Things Like

• Backend microservice architecture and API design.
• React-based frontend work.
• Databases, CI/CD, cloud (GCP).
• Shipping real products to real users.

A Few Practical Notes

• Stockholm and office-based, because we believe that great products and culture are better built when you meet in person.
• EU work authorization required.

Why Anyfin?

Because this is one of those moments where a company is about to level up: Banking license secured, expansion ahead and a lot to build. If you want to be part of a small, high-trust team doing meaningful work, we’d love to hear from you.

Anyfin is a fintech on a mission to simplify loan repayments and improve the financial well‑being of millions. We help consumers reduce the costs of high‑interest loans, and take control of their repayment plan.
