About the role:

As a Senior React Native Engineer, you’ll join a cross-functional product team and play a key role in shaping and building our mobile and web banking applications. You’ll work hands-on with React Native, React.js, and TypeScript, contributing to both the technical foundation and the user experience of our products.

You’ll help build customer-facing features for digital banking — including payments, credit, and personal finance tools — all designed to improve financial wellbeing.

You’ll work closely with backend developers, designers, and product managers to bring new features to life — always with performance, security, and usability in mind. You’ll also help guide architectural decisions and continuously improve our ways of working.

You’ll be based in Stockholm, working alongside a local and international team, including our Engineering Center in Katowice, Poland. 

Your background:

• Solid experience in building mobile and/or web applications
• Strong skills in React Native (CLI or Expo) and TypeScript
• Experience with React.js and building component-based UIs
• Familiar with web services and APIs
• Comfortable using modern dev practices (code reviews, CI/CD, testing)
• Exposure to Agile workflows

You are a creative and curious person with a genuine interest in software development. You’re excited about exploring new technologies and trends, and you enjoy sharing knowledge with your team.

Like us, you probably love writing clean, high-quality code — and you're not afraid to flag issues or suggest better solutions. You're a true team player who thrives in a collaborative, agile environment.

Bonus points if you also have:

• Experience with native Android and/or iOS development
• A degree in Computer Science, Engineering, or a related field
• Backend experience NestJS, GraphQL and familiar with Accessibility (a11y)

What we offer: 

• A key role in a product-first, cloud-native tech company

• The chance to shape both technical architecture and product direction

• A modern office in the heart of Stockholm, with a rooftop terrace and stunning views

• Collaboration with talented, humble colleagues in a flat organization

• Competitive compensation and benefits

• Support for your learning and development

• An open, friendly culture that values ideas over titles

Fun Facts:

• Daily breakfast, fresh fruit, and our sacred Friday fika
• Generous wellness allowance and regular visits from a massage therapist
• A treadmill in one of our conference rooms (yes, really!)
• Legendary “Northchill” afterworks and “Northcon” – our own internal conference (often held abroad)

• A team-first, non-corporate culture with space for big ideas and small rituals
