Our engineering department, the Bureau of technology

Our technology department, known as the Bureau of Technology (BoT), is at the heart of Back Market. It consists of over 30 dynamic product teams that are engaged in developing and managing services to deliver significant value to our customers and suppliers. These teams are effectively supported by our Platform group, which includes more than 10 specialized teams addressing cross-cutting technical issues to enhance our operational capabilities.

In addition to these functional teams, we have established numerous groups dedicated to sharing knowledge across various technical disciplines, such as security, backend, frontend, AI, and mobile. These groups serve as hubs for collaboration and professional development, providing ample learning opportunities and fostering a culture of continuous improvement.

Our staff engineers also play a pivotal role throughout the company, lending their expertise across different domains. They provide leadership and technical guidance, promoting alternative career paths for growth beyond traditional management roles.

As a Senior Backend 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 Backend 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.

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.  

As a Senior Backend Engineer, the challenge is three-fold:

1. Ensure a seamless transition with zero downtime and no revenue loss.

2. Reduce complexity while increasing adaptability of the codebase in the context of new country openings.

3. Guarantee high performance and reliability of production environments
