Special Objects. Serious Systems. Build the code behind it.
Building the technologies that transition the world of special objects from offline to online
Catawiki offers tens of thousands of special objects in auction every week. Our Engineering team is responsible for the magic behind each bid – building the infrastructure, features and experiences that our millions of buyers and sellers love.
We innovate in clusters of small, agile, cross-functional teams, focused on specific users (such as buyers or sellers) or specific parts of the customer experience (such as shipping or payments).
The Catawiki experience is available to our customers through a web browser or our iOS and Android apps. We strive to deliver a flawless experience across all three of these platforms.

Our tech stack
Our philosophy on tech stacks is to use the right tool for the problem we’re solving, but most of the time we use Ruby and Ruby on Rails on the backend, Typescript and React on the web frontend, and the native languages and UI frameworks for iOS and Android.
We run a Kubernetes orchestrated microservice architecture on the Google Cloud Platform (GCP). Each microservice encapsulates a part of our product domain, which allows us to iterate on new features quickly, scale each one as a separate entity in the system, measure and monitor its performance, and effectively isolate, identify and fix production issues whenever they occur.
Our specialty however, is using these modern technologies to build environments where people’s personal passions can thrive – both on our platform and in our teams. Catawiki’s novelties are thought up by a friendly and collaboration-focused team. Every colleague is valued and encouraged to learn and grow, so that we can tackle even the most challenging engineering problems together.
Meet Stefano
Sr. Vice President Engineering & Security
“I started using a computer when I was three years old. Since then, my fascination with technology and science fiction only kept growing, as my Lego and Star Wars memorabilia can attest. After a decade spent leading engineering teams at different companies, I decided to join Catawiki at the beginning of 2024 to lead Catawiki's Technology teams.
What fascinates me about working at Catawiki is the unique business problems we face and how this pushes all of us to find new and clever solutions to solve them. We get to pave our own way, and this isn’t something you can find everywhere.”
