Yep, you read that right. Turns out refurbished tech is way better for the planet than new. In fact, With every device purchased on Back Market, our positive impact on the planet grows. From our Customer Care representatives to our software engineer, every individual at Back Market cuts the planet — and consumers — a break. Our mission is simple: to do more with what we already have. About The Team The Sales Customer Care squad’s mission is to provide a seamless post-sales experience to our Customers and empower our Agents with the right tools to deliver timely and qualitative support. To achieve this, we closely collaborate with our Business and Operations partners to identify new opportunities to improve Customer and Agent experiences, and with other Care squads to deliver on them. 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.
