UI Engineer II

Your opportunity

In its journey to make payments and money management effortless for every business in Europe, Mollie is looking for software engineers to join our big team. With the headquarters in the very heart of Amsterdam, recently we successfully launched an Engineering Hub in one of the most vibrant cities in Europe: Milan!

As a UI Engineer on the "Product M" team, you will be an integral part of our Financial Services domain, currently focused on developing one of our future flagship products. You will collaborate with a multidisciplinary team of product managers, product designers, and product engineers (backend, UI, mobile, full-stack) to deliver the major edition of this new product that we would like to launch this summer.

This is a unique opportunity to be involved in a product launch from its inception, contribute to achieving product-market fit, and gain valuable experience in scaling up a new product.

While we keep the specifics confidential for now, we are eager to share more details with you about what’s cooking under the hood!

What you'll be doing

• Taking ownership of the end to end development of a new product with a dedicated team of 3-4 engineers

• Iterating from an idea to the final solution, shaping, building, testing, and measuring the performance of the features our customers love

• Challenging our ideas and bringing your own. We encourage each other to act this way, so you can expect the same from others

• Looking for ways to improve the state of our tech. We run a single codebase for our web app (React) and mobile app (React Native)

• Raising the bar of overall quality of our UI platform by working with a wider community of product designers & UI engineers within Mollie. We encourage you to contribute to our company-wide design system and other services and libraries

Our architecture

Mollie’s frontend landscape consists of multiple apps, each optimized for its specific purpose, such as our merchant dashboard, API documentation, and mobile apps. Our apps are generally written in TypeScript using React. Our backend system is primarily written in Java (Spring Boot), hosting them on Google Cloud. Many adjacent services are built in PHP and also run on Google Cloud. We prioritize performance, stability, and resilience, continuously enhancing our applications to handle the next phase of growth.

What you'll bring:

• A minimum of 3 years of experience in developing complex, appealing and responsive web applications

• Experience with one of the modern JavaScript frameworks and libraries such as React, Vue, or Angular

• Knowledge of language primitives. You should feel comfortable interacting with native APIs built into the browser

• An eye for detail, text and layout composition

  
  

Nice to have

• Experience with React Native is a big plus; this role will require you to learn React Native, because we run single codebase across our web and mobile apps.

• Experience with TypeScript, Google Cloud Platform

• Experience mentoring other engineers. You like helping others grow

• Experience working in multi-disciplinary teams (backend and UI engineers, product designers and other roles). You come with a formed view on what works well and what doesn’t

  
  

We know how hard it is at times to self-evaluate. Like in this case: you might read ‘experience developing complex apps’, and might be in doubt after that - ‘did I really build apps that are complex enough?’

Many of us at Mollie recall those moments of doubt when applying to vacancies too. With this we would like to encourage you: if that’s how you just felt - please click apply. It speaks a lot about your personal strengths.

We at Mollie promise a non-judgemental and casual environment during interviews, and we consistently hear from candidates that this is how they perceived this process.

Please apply with your CV in English

Kindly note that relocation support is not offered for candidates outside of Europe for this role.
