Backend Engineer

At Catawiki, every day brings the extraordinary! Whether it’s Daniel Ricciardo’s Formula 1 Car , a Woolly Mammoth’s Skeleton , Lady Gaga's Jumpsuit or Usain Bolt’s running shoe , we encounter exceptional objects every day.

We’re a one-of-a-kind marketplace for buying and selling special objects. Each week, more than 100,000 unique items are auctioned, all carefully curated by our passionate in-house experts.

Having sold over 25 million unique objects, our mission is to become the world’s most popular destination for special objects. As a growing, diverse and sustainable scale-up, we proudly live by three core values. If these values resonate with you, we’d love to explore how you can join us.

• Taking ownership and driving impact

• Being open to change and feedback

• Being passionate about our mission and our customers.

• improving and delivering product innovations for our platform.

Working in a small, fully autonomous, and highly collaborative Agile team, you will build scalable, maintainable, and resilient microservices and features. That’s why we’re looking for developers who share ideas, explore options, and communicate openly.

You understand the full lifecycle of web development, identify opportunities, explore solutions, and keep customer needs at the center of your work. Our stack is mainly focused on Ruby; however, prior Ruby experience is not essential if you’re passionate about learning new things.

• Collaborative mindset: You contribute to the team, take initiative, and step in to help when needed.

• Solution-oriented thinking: You actively identify opportunities and explore alternative approaches to solving problems.

• Commitment to growth: You take ownership of developing your skills by learning new technologies and seeking new opportunities.

Our engineers work in small, fully autonomous, and highly collaborative Agile teams aligned with one of three verticals: Demand, Supply, or Fulfilment.

• Teams are responsible for their own microservices from design and development through deployment, maintenance, and improvement.

• Engineers collaborate closely with product designers, product owners, and frontend, backend, and mobile colleagues.
