Senior Backend Engineer - Platform Team in Amsterdam, Nederland


Senior Backend Engineer - Platform Team

Catawiki’s purpose is to enable people to discover and obtain special objects that help them fulfill their passions. In doing so, we add some color & make the world a more interesting place.

Our Backend Engineering Story

Our development team is responsible for the stability, reliability, and versatility of Catawiki’s platform. We are building new and exciting product features to craft an engaging platform, where our users can offer and discover special objects. At the same time, we are moving the platform towards a microservices architecture by gradually dismantling a Ruby on Rails monolith.

Here’s Vitali, one of our Platform Engineers:

“I joined Catawiki right before the moment when we started microservices migration. On the way together with my brilliant teammates, we’ve resolved thousands of issues connected to performance, maintainability, scalability, reliability, observability, and security topics.

Now in the Platform Runtime team, we keep up consistent development of almost 50 services as a whole providing compatibility layer linking our systems with the feature development, reducing toil, and supporting spreading reusable solutions amongst different teams.

I am really proud of what we’ve achieved during the last 5 years. And I’m looking forward to what we can achieve in the future because change is the only constant in life.”

So what's the job

Here at Catawiki, you will make an impact by improving and delivering product innovations for the Catawiki platform.

Along with the other members of the Platform Runtime team, you will work on providing frictionless developer experience through a collection of tools, automation, and best practices helping Catawiki Engineers to focus on what matters for Catawiki customers.

How we roll - Our Stack

As the biggest marketplace for special items, Catawiki operates in a market, which brings a lot of unusual challenges and opportunities. You will be developing, testing, and scaling our microservices, written in Ruby and some of them in Go, to handle the high volume served by the platform every single day. We do this by using Infrastructure as Code principles, collaborative peer-reviews, delivering code to production multiple times a day, A/B testing every assumption, making mistakes, learning from them, and iterating quickly.

You'll move in sync 

You will be part of a team focused on a particular domain within Catawiki and contribute your ideas and efforts to grow the business and innovate the product. 

A little about you 

It doesn't matter what stack you're used to working with, as long as you're motivated to learn new things, ship new features, and pursue new and interesting challenges. Our stack is mainly focused around Ruby, so if you are not experienced in it, it will be highly valued that you're passionate about learning new technologies.

Next to this:

  • You have experience in designing, developing, and deploying backend services with a focus on high availability, low latency, and scalability.
  • You have proven experience of collaborating closely with other engineers to become a valued member of an autonomous, cross-functional team.
  • You understand the value that you can add to the business, the product and the impact of your work on users.
  • In the platform-runtime team, we communicate a lot to our colleagues thus good writing skills is a nice-to-have bonus.

The Catawiki Story

A piece of the moon, a complete dinosaur skeleton, the Pope's hat, the world's smallest book - at Catawiki, we come across exceptional objects such as these every single day. As Europe’s fastest growing online auction platform, our mission is to make special objects available to everyone.

In fact, 14 million users are buying and selling on Catawiki every month. This means we are continually growing and always on the lookout for new talent.

Born and raised in The Netherlands, we started in 2008 as a platform where collectors could manage their collections online. Yet, times change, ideas evolve, and in 2011 we hosted our first online auction and we haven’t looked back since! We’ve now grown to 500 Catawikians working across 7 International offices and are proud to have maintained our start-up mentality.
