From our Customer Care representatives to our software engineer, every individual at Back Market cuts the planet - and consumers - a break.

About the team

[INSERT TEAM PRESENTATION]

As a Software Engineer , you will work closely with all members of your squad, and the Staff engineer of your group. Bi-monthly rituals with your group and the Chapter will allow you to share what works for your squad, learn what works for others, and make sure your technical direction is aligned with the overall vision.

What you will do in this role

We're looking for versatile engineers who show strong ownership and are motivated to take on new challenges across the technical stack while helping us move our technology forward. You will be working in an agile "build it and run it" environment where engineering teams build, launch, monitor and support the product that they own.

Driven by the desire to craft outstanding products, you understand how to deliver seamless user experiences at scale. We are looking for passion in creating systems by producing clean, consistent and well-organised code.

Main technical challenges

Traditionally based on a monolith, Back Market's technical stack has been undergoing a radical transformation in recent years into a distributed and service-oriented architecture. This transition provides an opportunity to modernize the platform, raising engineering standards. Building a set of efficient and loosely coupled services is one of the main challenges to face for the years to come. But teams are excited to independently control their release schedules, manage their data, SLAs, tools, and - ultimately - be responsible for their own service-offering. Meanwhile, Platform teams are working to provide a scalable, consistent and secure platform, one that makes engineering teams more productive.
