MEET THE TEAM!

Fraud Operations is a key function within Preply's Customer Care organisation, responsible for protecting the financial integrity of our marketplace and ensuring a safe, trusted experience for learners and tutors globally. The team operates across fraud investigations, dispute resolution, and chargeback management — partnering closely with Product, Payments, and Finance to manage risk at scale.

As Fraud Prevention Manager, you will lead this team and serve as Preply's primary fraud operations authority — owning the function's strategy, operations, and people end-to-end.

WHAT YOU’LL BE DOING

• Lead, manage, and develop a team of Fraud Specialists, setting clear expectations, coaching performance, and building a high-judgement, high-accountability team culture

• Own the Fraud Operations roadmap, defining priorities and aligning the function's objectives with broader business goals

• Design and formalise investigation standards, workflows, escalation protocols, and documentation frameworks across the team

• Define, track, and continuously improve Fraud Ops KPIs — including chargeback rate, dispute resolution SLAs, false positive rate, and financial exposure metrics

• Establish a governance cadence: risk reviews, exposure reviews, and threshold calibration with Finance and senior leadership

• Serve as the eyes on the ground for Product and Data — systematically translating what Specialists observe day-to-day (fraud patterns, tooling gaps, detection blind spots) into structured, actionable requirements that directly shape the detection roadmap

• Cross operational observations with data to identify gaps between what is happening on the ground and what detection models are actually capturing — bringing Product and Data leads trends they can act on, not just dashboard summaries

• Partner with Product, Payments, and Finance as the primary fraud authority, influencing priorities and ensuring fraud risk is embedded in key decisions

• Own workforce planning and capacity management to ensure operational resilience

• Present fraud performance, risk insights, and strategic recommendations to senior leadership

• Drive continuous process improvement through root cause analysis, policy adherence, and tooling evolution

WHAT YOU NEED TO SUCCEED

• 6-8+ years of experience in fraud operations, payments risk, or financial crime — with demonstrated people management experience

• Proven track record leading fraud or risk operations in a marketplace, fintech, or e-commerce environment

• Deep expertise in fraud investigation methodology, chargeback management, and fraud detection workflows

• Experience owning operational KPIs and translating data into decisions and priorities

• Strong people leadership: you build teams, develop talent, and create cultures of rigour and ownership

• Able to translate operational observations into clear requirements for Product and Data — comfortable working with PMs and data leads as peers, not just as stakeholders to manage

• Strong data fluency: you combine what you see in operations with what the data shows, identify gaps between ground-level reality and what detection is capturing, and surface actionable trends

• Skilled at designing scalable processes and governance frameworks that outlast any individual

• Strong understanding of how AI and machine learning models are applied in fraud detection — including how to interpret model outputs, evaluate signal quality, and partner with technical teams to drive detection improvements

NICE TO HAVE

• Familiarity with ML-based fraud detection and feedback loop workflows

• SQL or BI fluency (e.g. Looker, Tableau)

• Experience in a multi-currency, cross-border marketplace environment

• Certified Fraud Examiner (CFE) or Certified Anti-Money Laundering Specialist (CAMS)

• Experience with fraud detection platforms (e.g. Sardine, Sift, Feedzai, Kount)
