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?

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.

But what does this team do at Back Market?
Act as a Back-Bone and orchestrator for the order lifecycle, enabling the seamless launch of new products and services to propel the company's growth.

As a Senior Backend Engineer II, 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.

Our technical environment

Application: Python - FastAPI / SQLAlchemy/ Celery/ Golang/ Django (being phased out)
Data: PostgreSQL/ Redis/ Kafka/ RabbitMQ/ BigQuery
Infrastructure: GCP / Kubernetes (GKE) / Docker/ Datadog/ ArgoCD / CircleCI / Github

What you will do in this role 🕵️
We are looking for a Senior Backend Engineer to help us build & operate a set of efficient, high cohesion, low coupling services with security and privacy by design in order to support the growth of the business.
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.
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)
