Backed by world-class investors and valued at over €1.75 billion, they operate at a significant scale where the engineering division is the core of their success, fostering a culture of technical excellence, agility, and high impact.

The Role: A Mission for Elite Engineers

This is not a standard development role. We are mandated to find exceptional Senior Backend Engineers to join our client's elite team in Paris. The selected candidates will be instrumental in designing the future of the platform, evolving its architecture from a monolith to a distributed microservices system, and pioneering the integration of Generative AI to create a genuine competitive advantage.

You will operate within an autonomous, cross-functional squad, collaborating with top-tier Engineering Managers, Product Managers, and Designers to solve complex challenges that define the future of European e-commerce.

Key Responsibilities

• Architectural Evolution: Actively contribute to the design and implementation of a scalable, resilient, and performant microservices architecture.
• Core Feature Development: Design, develop, and maintain critical backend services using PHP 8.3 (Laravel 10) and/or Go.
• AI Integration: Explore and implement innovative features leveraging Generative AI, transforming the product offering and user experience.
• Technical Excellence: Write clean, maintainable, and rigorously tested code. Champion best practices in software engineering, including comprehensive code reviews and robust documentation.
• Mentorship: Mentor other engineers, elevating the team's technical capabilities and fostering a culture of continuous improvement.
• System Reliability: Participate in the on-call rotation to ensure the stability and high availability of the production environment.

Your background must demonstrate a clear ability to thrive in a fast-paced, demanding environment.

Technical Mastery:

• Demonstrable expertise in either PHP (with a modern framework like Laravel or Symfony) or Go. Proficiency in both is a significant asset.
• Proven experience in designing and building RESTful APIs and working within a microservices architecture.
• Strong command of database design and optimization, particularly with MySQL.
