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.

Small team, high responsibility

We hire carefully. We’re not a company that grows by adding headcount everywhere, we grow by keeping the bar high and building a team where every person matters.

This isn’t a place where you disappear into a big org. If you join, you’ll have real influence on what we build and how we build it.

What you’ll do

You’ll work across the stack, end to end:

• 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.

We’re also actively working towards becoming more AI-native in how we work. Not as hype, but as a way to iterate faster and spend less time on repetitive stuff.

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. Apply only if you want the responsibility that comes with real impact.
