Senior Front-End Developer

What you will do

As a Senior Front-End Developer for Catawiki you’ll be part of an agile development team of 50+ developers and will mostly be developing parts of the product that are used by our millions of customers. You will interact with our Back-End, UX, Product Management, Data and Marketing teams (plus Catawiki’s users!) as you develop new functionality to:

  • Bring your own ideas to improve the product with an iterative, small-steps approach through A/B testing.
  • Collaborate with the designers in your team to develop the best user experience for our customers.
  • Work closely with the Back-End Developers in your team to build APIs and improve performance.
  • Work in a modern ES6 environment.
  • Migrate our not-so-modern jQuery application to React 
  • Work with the wider Front-End team to help us migrate to Typescript

Who you are

A data-driven Front-End Developer with good communicative skills, and a Bachelor’s or Master’s degree in information technology (or similar). Naturally, you’ll need to be familiar with the following:

  • HTML5 / CSS3 / Javascript.
  • The quirks of modern and less up to date browsers.
  • Responsive design.
  • Ideally, experience with Ruby on Rails, React, Typescript SASS and/or HAML, but it is not essential.

What we offer

This is your chance to become part of Europe's fastest growing tech company! You will have an exciting job in a young, fast-growing, dynamic & international organisation. In addition we will make sure you have a soft landing, should you have to relocate to the Netherlands.
Additionally, you can expect:

  • 25 days Paid holiday & holiday allowance
  • The Catawiki pension plan (no contribution from the employees, so Catawiki is paying for the whole pension plan)
  • Excellent opportunities for career development
  • Sponsored events and afternoon drinks
  • A fun team in a fast-growing online company facing complex challenges
  • Lots of room to work on great ideas, and to learn and grow
