If these values resonate with you, we would love to explore how you can join us on this exciting journey!

How they work

As the biggest marketplace for special items, we operate in a domain that brings plenty of unusual challenges and opportunities. You will be developing, testing and scaling 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 and learn valuable lessons from them. Our focus is to be able to recover and iterate quickly.

What you’ll do

You will make an impact by improving and delivering product innovations for our 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.

Where you’ll be

This role is based in Lisbon, Portugal. We also offer an excellent relocation package for people living outside of Portugal.

Their Offices and Way of Working

Their vibrant offices in Amsterdam, Paris and Lisbon are designed to inspire and connect. They are within commuting distance of one of our offices and enjoy the flexibility of a hybrid work model.

That said, some roles may be an exception: if the job description states that the position is fully remote or 100% office‑based, that arrangement will apply instead.
