Senior Backend Developer - Pt (Internet Marketplace Platform)

How we work:

As the biggest marketplace for special items, Catawiki operates in a domain that brings plenty of unusual challenges and opportunities. You will develop, test, and scale our microservices, mostly written in Ruby, to handle the high volume of requests served by the platform every single day. We do this by using Infrastructure as Code principles, collaborative peer reviews, continuous delivery, A/B testing every assumption, and using the observability and monitoring tools already in place. We make mistakes, learn valuable lessons from them, and focus on recovering and iterating quickly.

What you’ll do:

Here at Catawiki, you will make an impact by improving and delivering product innovations for the Catawiki platform. Along with other members of the Development team, you will build scalable microservices while measuring and monitoring system performance. In addition, you will use experimentation backed by data analysis to add product features and deliver the best user experience on the platform.
