Senior Fullstack Engineer (Stockholm, EU only)
Anyfin AB · Stockholm · Tills vidare
Anyfin is hiring a **Senior Fullstack Engineer** based in Stockholm to help scale its consumer finance platform following its acquisition of a banking license. Working end-to-end across the stack, the role involves building and shipping features across backend, web, and mobile systems using TypeScript, Node.js, React, and React Native. Responsibilities center on owning projects from ideation through production, making product and technical architecture decisions, and scaling high-reliability services handling real financial transactions. The team emphasizes an AI-embedded development workflow and requires **in-person collaboration** with product and design colleagues on a weekly basis. Candidates must have **solid fullstack experience** along with valid EU work authorization. The role requires proven familiarity with backend microservice architecture, API design, React-based frontend development, databases, CI/CD, and cloud platforms such as Google Cloud Platform (GCP). The position is aimed at engineers with strong technical judgment who are comfortable shipping real products independently, navigating complex problems, and actively shaping technical direction in a high-ownership environment.
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.
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.
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 and collaborative team.
- 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 based.
- 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.
