React Native Engineer

Your opportunity

For our development hub in Lisbon, Portugal, we’re looking for a React Native Engineer to join the Mobile App team. This team focuses on evolving our mobile app that enables merchants to manage their business in a consistent and localized user experience at all times.

Currently, the Mobile App team is closest to our end-users: the employees of the 130,000 businesses Mollie processes payments for. The team is responsible for our iOS & Android apps, which are being used by tens of thousands of users daily (and we expect this to double over the next year).

The team is 100% data-driven and has ambitious KPIs to ensure we focus on the right things. We work in an agile environment where everyone gets a lot of autonomy as long as it adds value to the products that users love to use.

We’re looking for people who enjoy solving complex challenges while keeping the user experience in mind at all times.Join us and be part of a great journey.

What you'll be doing

Although Mollie already had a mobile app for a few years, we are now aiming at scaling this product even further and unlocking our merchants' full potential. We want to offer our merchants better features to help them manage (and grow) their business on the go in the app.

As a React Native Engineer in the team, you will be responsible for  improving existing and building next-level (native) features. You will work closely with our UX designers, backend engineers, product managers, and other React Native Engineers to ensure we always deliver the best user experience while staying as independent as possible from other teams. By working in a multidisciplinary team, we have very few dependencies, allowing us to move faster at all times.

Furthermore, we love our tech stack, and you will be asked to work with other team members in taking the developer experience of the Mollie app to the next level. So that not only our end users but everybody at Mollie would benefit from your work too.

We believe in end-to-end ownership. As such, you will be expected to release new features yourself using our Gitlab pipelines.

Our architecture

Our mobile app is based on React Native (powered by the Expo framework) and is fully written in TypeScript. The app communicates with our backend through a large set of private APIs (shared between our mobile app and the Mollie Dashboard).

While most of our screens are written using React (Native), for some features, we communicate with the native layers using actual native modules (Swift / Kotlin).

What you'll bring

• A minimum of 3 years of experience in developing complex React Native applications.

• The drive to make our product available to everyone by applying accessibility standards.

• A knack for creating intuitive user experiences. You love working closely with UX designers to build the best app out there.

• You know how to pinpoint performance issues and bring suggestions to the team on how to improve the performance of our frontend apps.

• Experience with test-driven development and end-to-end testing of React Native applications. We use BrowserStack Live Automate for end-to-end testing.

Nice to have

• Experience with Kotlin, Java, Swift, or Objective-C is a big advantage.

• Solid knowledge of iOS or Android Experience publishing apps to the App Store / Google Play Store (using Fastlane is an advantage( – at Mollie, we give the teams the autonomy to ship features to production. You will, of course, do this in close collaboration with your product manager and we have a QA process in place.

• Experience with design systems and/or internally developed component libraries.

• You’re familiar with Redux (and its ecosystem), and styled-components (in React Native environments).

• Experience working with monorepos (Nx, Turbo, Lerna, etc…)
