Senior Software Engineer - Backend (Hybrid Remote)

We’re here to help make tech reliable, affordable, and better than new . We're a global marketplace for refurbished devices, helping lower our collective environmental impact by providing trustworthy, affordable tech with 92% less carbon emissions than new.
Turns out refurbished tech is way better for the planet than new. From our Customer Care representatives to our software engineer, every individual at Back Market cuts the planet — and consumers — a break. The Code Foundation team is dedicated to providing foundational tools, libraries, and standards that enhance developer productivity and ensure consistency across application development. By fostering a culture of experimentation and enabling robust observability, the team empowers developers to deliver high-quality products efficiently and effectively.
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.
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. English must be a no-brainer as you will join an international team dispatched in different locations around the world (US/FR/ES/JP).
