Our CIAM team is looking for a Backend Product Manager – Customer Identity (f/m/d) on a Permanent Contract (CDI), located in Paris.

Team Overview: The CIAM (Customer Identity and Access Management) team is at the heart of Decathlon’s strategy. Our goal is to transform our identity management foundation into a strategic growth engine. We manage a global platform providing a unique international account across 80 countries for millions of customers, handling over 1 billion API calls per month.

• Delivery & Product Quality: Validate feature compliance (security and GDPR), measure the impact on user satisfaction (CSAT), and contribute to technical excellence via full CI/CD automation.

• Transversal Collaboration: Act as the privileged interface between users and the technical team, lead agile ceremonies, and collaborate closely with front-end, Tech, Data, Support, and Design teams.

• Data-Driven Steering: Design robust logging to monitor performance, translate business KPIs into high-performance backend requirements, and execute server-side A/B tests.

• An investigative mindset, excellent communication skills to simplify complex tech topics, and resilience to manage a high-traffic product.

• Fluent English is mandatory.

• Bonus: Familiarity with CIAM, OAuth2/OpenID standards, GDPR compliance, and fraud prevention.
