Description du poste

Hi, we're Back Market. 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. 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. Are you ready to join us?

About the team

The Delivery Experience squad's mission is to provide a seamless and transparent delivery journey for our Customers, while empowering our Agents and operational partners with the right tools to manage delivery-related questions and issues efficiently. To achieve this, we work closely with our Business and Operations partners to identify opportunities to improve every stage of the delivery experience, from order tracking and carrier coordination to delays, incidents, and delivery exceptions. We also collaborate with other Care squads to build consistent and connected experiences across the customer journey.

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. As well as a good team player supporting colleagues and creating a learning and sharing environment! English must be a no-brainer as you will join an international team dispatched in different locations around the world (US/FR/ES/JP).

Our technical environment

• Backend stack: Python - FastAPI , SQLAlchemy, Celery, Golang, Django (being phased out)
• Frontend stack: VueJS, Typescript, Nuxt, Revolve ( our design system)
• Data: PostgreSQL, Redis, Kafka, RabbitMQ, BigQuery
• Infrastructure: GCP, Kubernetes, Docker, Datadog, ArgoCD, CircleCI, Github

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.
