  • 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

Requirements

  • A minimum of 4 years experience in developing large-scale web applications
  • Strong knowledge of Java (Spring Boot) and TypeScript (React)
  • Knowledge and/or experience with domain-driven or service-oriented architectures

Nice to have

  • Previously worked with PHP, TypeScript, React(.Native), Google Cloud Platform
  • Previously worked within the Payments, FinTech or high scale B2B SaaS space
  • Track record of leading complex cross-functional or cross-team initiatives to their success
  • 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

What we offer

  • 20 days working from abroad
  • Wellbeing Budget €60 per month net
  • Lifestyle and Health Support via OpenUp
  • 26 holiday days plus an extra 2 days off in between 27 and 31 December
