React Native Engineer

Gimi; Stockholms kommun; On-site; SEK 700,000 - 900,000; Full time

Job summary

Gimi is a small team building the financial infrastructure banks use to teach kids and teens how to handle money—real accounts, real payments, real habits.

As a React Native Engineer you'd join our mobile team at a point where the work is concrete and shipping fast: right now that means our end-to-end allowance system — the weekly pocket money flow that runs for thousands of families, from parent setup to the ledger that tracks every transfer.

Qualifications

• Shipped real React Native apps to production.
• Able to code in JS/TS and work with Node.
• Build with AI tools day to day and have opinions on where they help or hinder.
• Able to explain a technical decision you made and why.

Responsibilities

• Build and ship features in the React Native app, beyond maintenance.
• Collaborate closely with product, design, or other engineers.
• Make trade-off calls when edge cases arise in recurring flows.
• Leverage AI tools as a core part of scoping and shipping.
• Write clean, maintainable code that teammates can pick up easily.

Job description

Gimi

We're a small team building the financial infrastructure banks use to teach kids and teens how to handle money — real accounts, real payments, real habits. As a React Native Engineer you'd be joining our mobile team at a point where the work is concrete and shipping fast: right now that means our end-to-end allowance system — the weekly pocket money flow that runs for thousands of families, from parent setup to the ledger that tracks every transfer.

What you'd actually be doing

• Building and shipping features in our React Native app — not just maintaining, actual new product surface

• Working closely with the person next to you (product, design, or another engineer) rather than waiting for a spec to land

• Making real calls on tradeoffs — e.g. when an edge case in a recurring payment flow breaks, deciding how much complexity to absorb quietly vs. surface to the user

• Using AI tools as a core part of how you build — from scoping to shipping — not as an occasional shortcut

• Writing code your teammates can pick up without you needing to explain it in Slack afterward

What we're looking for

• You've shipped real React Native apps to production — show us, don't just tell us (a GitHub link, an app you've worked on, whatever proves it)

• You're comfortable with JS/TypeScript and can hold your own around Node

• You already build with AI tools day to day and have a real opinion on where they help and where they don't — this matters more to us than most other lines on this list

• You can explain a technical decision you made and why, including one you'd make differently now

Nice to have

• Native iOS or Android experience

• CI/CD experience

• Firebase

• Fintech, or any regulated/compliance-heavy industry

To apply

Skip the generic cover letter — instead, tell us about a bug or technical problem you found genuinely satisfying to solve, and what made it hard.
