Product Owner / Business Analyst (H/F)

Why this role is key

Between customer experience, security constraints, and fraud sophistication, your role is to find the right balance. You don't secure "randomly": you design journeys that resist attacks without breaking usability. 👉 We are supporting a major banking player on online fraud and digital journey security topics. For this, we are looking for Product Owner / Business Analyst profiles (M/F) capable of understanding the product, security, and user behaviors.

Your mission

Concretely, you will intervene at the heart of digital journeys:

• Secure sensitive journeys (payment, transfer, authentication)
• Identify fraud risks and propose adapted prevention mechanisms
• Define detection rules (alerts, suspicious behaviors, risky scenarios)
• Write clear specifications (events, logs, controls)
• Work with data and security teams to improve detection
• Analyze concrete fraud cases and adjust existing systems
• Constantly arbitrate between security and user experience
