The posting

Are you interested in joining of Europe's fastest growing companies? Do you want to impact the wellbeing of millions of employees?

If yes, then keep reading and join us to make an impact in a fast-paced and dynamic environment where you’ll play a key role in boosting everyday wellbeing, at home, at work. Everywhere!

Epassi’s purpose is to boost everyday well-being. We are a leading provider of employee benefit solutions across Europe. We were established in Finland in 2007, and in 2008 we were the first company to launch a mobile-payable employee benefit payment solution in Europe. Since then, we have consistently grown, diversifying our products and introducing our services into new markets.

Epassi has been awarded by the Financial Times as one of the fastest-growing companies in Europe on multiple occasions.

We are strengthening our mobile engineering team to build and scale a unified consumer app platform, starting in Germany and growing across the EU. This role exists to establish a solid, scalable React Native foundation built for long-term growth.

This role sits within the Engineering function and is part of a cross-functional product team of 8 engineers, one product owner, one designer, and one QA.

The Role

You will take ownership of the Epassi consumer mobile application - designing, building, and evolving it with quality, scalability, and long-term maintainability at the centre. You are the engineer who ensures our React Native app can grow as fast as our ambitions demand. You will contribute to architectural decisions and shape how we build, operate, and continuously improve mobile solutions across the Epassi group.

Success Criteria

  • The mobile app is stable, well-structured, and shipping reliably on a weekly delivery cadence within the first 90 days
  • Architectural patterns are in place that support long-term scalability and modularisation
  • Technical debt is actively identified and reduced, not just managed
  • You are a trusted, effective collaborator across Product, Design, Backend, QA, and DevOps

Key Responsibilities

Mobile Engineering (primary focus)

  • Build and maintain high-quality mobile features using React Native, TypeScript, and Expo
  • Write clean, testable, and maintainable code and hold peers to the same standard through code review
  • Integrate REST and/or GraphQL APIs in close collaboration with Backend Engineers
  • Monitor app behaviour, analyse issues, and support incident resolution
  • Write and maintain end-to-end tests (e.g. using Maestro or equivalent tooling) to ensure consistent quality

Architecture and Technical Ownership

  • Shape and refine the mobile app architecture with scalability and modularisation as guiding principles
  • Lead and contribute to architectural discussions and document decisions clearly
  • Proactively identify and reduce technical debt
  • Support build, release, and deployment processes for iOS and Android, including ownership of Google Play Console and App Store Connect processes

Release and Delivery

  • Own the full app release management cycle end-to-end, from build pipelines through to publishing on Google Play Console and App Store Connect
  • Manage source code using Git or equivalent source code management tools, maintaining clean branching and release practices
  • Work within a weekly delivery cadence: plan on Monday, demo to leadership on Friday
  • Participate in agile ceremonies (planning, refinements, reviews, retrospectives) while keeping meeting load lean so the team can focus on delivery

Cross-functional Collaboration

  • Work closely with Product Owners and Designers to refine requirements and deliver user value
  • Collaborate with Backend, QA, and DevOps to support smooth operation under a "you build it, you run it" mindset
  • Leverage AI-native development tools and workflows (such as Copilot, Cursor, and Claude) to accelerate delivery and improve code quality - and set the standard for AI-assisted engineering practices across the team

You'll be a great fit if you have:

  • 5+ years of hands-on experience with React Native (non-negotiable for this level)
  • A track record of delivering mobile applications or major features end-to-end
  • Solid experience with app release management, including Google Play Console, App Store Connect, or equivalent deployment tooling
  • Experience contributing to or shaping scalable mobile architectures in long-lived products
  • Worked effectively in cross-functional teams alongside Product, Design, and Backend
  • Comfortable working in a high-pace, high-change environment where the team ships weekly
  • Java experience is a bonus - useful given the team's cross-functional setup and occasional need for backend support

Your Key Attributes

  • Takes ownership of quality and reliability, not just the ticket
  • Communicates clearly and collaboratively across disciplines - engineers, designers, and product people alike
  • Comfortable operating in a high-pace environment where things move and change quickly
  • Proactive about raising and addressing technical debt rather than working around it
  • Embraces AI-native tooling as a genuine accelerant, not an afterthought
  • Languages: Fluent English required. German is a bonus.

Tools: React Native, TypeScript, Expo, Git, Google Play Console, App Store Connect, E2E testing tools (e.g. Maestro), AI development tools (Copilot, Cursor, Claude)

Why You Should Join Us

  • Be part of an ambitious growth journey and join a global community of driven, bold, entrepreneurial, yet humble Epassians in a company that is constantly evolving.
  • Work with a clear purpose — boosting everyday wellbeing — and create a meaningful, positive impact on both individuals and society.
  • Thrive in an open and inclusive culture with low hierarchy, where relationships are built on respect, camaraderie, and shared successes and challenges.
  • Come as you are — we’ll bring out the best in you and support your personal and professional growth.
  • Join a fast-growing tech company with a strong financial foundation, offering opportunities to grow and make an impact together with us.
  • Benefit from an inspiring and supportive work environment where employee wellbeing is a true priority.
  • Contribute to solidifying our position as the number one player in Europe’s employee benefit market and help shape the next wave of success.

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
