Lead Fraud Ops (FR)

Job Description

About the role

We are looking for a Lead Fraud Ops to protect a fast-growing app from fraud, while keeping the experience fair and rewarding for millions of walkers.

Reporting directly to Aurélien (CTO), you will play a central role inside the Data team and work closely with all departments (Tech, Product, Growth, Customer Support, Finance). You’ll be the bridge between field investigation, user behavior analysis, and technical solutions.

Your mission will be to detect, investigate, and outsmart fraudsters: from spotting suspicious patterns to interviewing users, reproducing fraud schemes, and transforming insights into concrete fixes with the Tech team.

By joining WeWard, you’ll step into a position with high visibility, strong ownership, and immediate impact on both our business and our community.

Your impact & responsibilities

• Own the fraud and risk strategy across the product, combining quantitative analysis with advanced qualitative investigations.
• Lead complex and sensitive investigations, deep-diving into user behaviors, fraud mechanics, and systemic vulnerabilities.
• Translate field and data insights into clear product, tech, and risk roadmaps, influencing prioritization and design decisions.
• Drive end-to-end remediation: issue prioritization, coordination with senior engineers, and long-term risk mitigation.
• Build and maintain a 360 view of risk (user fraud, payment flows, operational and banking vulnerabilities).
• Act as a senior stakeholder for payment, cashout, and gift card flows, balancing fraud prevention and user experience.
• Serve as the main point of contact for banking and redeem partners, overseeing anti-fraud topics, SLAs, and financial flow integrity.
• Define the right balance between automation, tooling, and human review, improving detection efficiency at scale.
• Lead continuous improvement initiatives: behavioral scoring, dashboards, alerting systems, and process automation.
• Partner closely with Product, Tech, Data, Customer Support, Finance, and Admin teams to align fraud strategy with business growth.
• Contribute at a strategic level to R&D initiatives on fraud detection, behavioral modeling, and risk anticipation, including thought leadership and publications.

Preferred Experience

• Education: Master’s degree (Engineering, Statistics/Data, MIAGE, or equivalent)
• Experience: +4 years as a Fraud Analyst, Risk Analyst, Business Analyst, or similar role in a B2C/app/fintech environment, ideally with some exposure to fraud or user investigation.
• Languages: fluent in French, good command of English
• Skills:
  • Strong in SQL and Excel (must-have)
  • Python is a big plus
  • Experience with analytics tools (Amplitude or equivalent)
• Mindset:
  • Comfortable with both quantitative analysis and direct user interaction (you don’t mind picking up the phone or talking with users on Discord, Reddit, or Telegram)
  • Curious and persistent: you don’t stop at the first “fake” explanation
  • Able to form hypotheses and test them quickly in the field
  • Great at making things simple: you can explain insights without unnecessary jargon
  • Impact-driven, pragmatic, and motivated by the thrill of finding loopholes

Benefits

• A global, mission-driven team with teammates in Paris, New York, London, Boston
• A healthy work/life balance
• Annual learning & dev budget
• Hybrid work, with 2 days of remote work per week
• Cool office in central Paris with snacks, a walking desk and a huge Wardy hanging around
