Senior React Native Engineer

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 react native 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 take a leading role in building and evolving our mobile applications across iOS and Android.

• Building and shipping new mobile features in React Native.

• Designing reusable components and scalable mobile architecture.

• Collaborating closely with design to deliver polished, accessible user interfaces.

• Integrating with our GraphQL APIs to power seamless user experiences.

• Making architectural decisions that improve performance, maintainability and developer experience.

• Running experiments and iterating on features to improve user engagement and retention.

• Writing and maintaining automated tests to ensure reliability across releases.

• Mentoring other engineers and helping raise the bar for mobile development.

Tech stack:

Mobile: React Native, TypeScript, Apollo Client (GraphQL)

Backend you'll work closely with: Node.js/Express, GraphQL Federation, PostgreSQL, Redis

Infrastructure: GCP, Kubernetes, GitHub Actions

Product tooling: Storybook, GrowthBook

How we think about building

We’re pragmatic. We like speed, but we also care about building things that last.

AI is already part of how we build and not an aspiration. We use Claude, OpenAI, and Mistral in our product, and we expect our engineers to actively explore how AI tooling removes friction from day-to-day work: in code review, test writing, and prototyping. We're looking for someone who sees AI as an amplifier of craftsmanship and not a substitute for it.

No ego. Just good judgment and high output.

You’ll thrive here if you…

• Have strong experience building mobile apps with React Native.

• Care about craftsmanship, performance and user experience.

• Take responsibility naturally and don’t wait to be told what to do.

• Enjoy collaborating closely with design and product.

• Like being part of an ambitious team working together in the office.

• Want to build and improve products, not just maintain them.

You’re comfortable with things like:

• React Native and modern TypeScript-based development.

• Mobile architecture and reusable component design.

• API integrations (GraphQL or REST).

• Testing strategies for mobile applications.

• Shipping real products to real users.

A few practical notes

Stockholm and we're office-based, because we believe that great products and culture are better built when you meet in person. There is flexibility of course, but you should want to work on site with the rest of us most days of the week.

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.
