Head of Fraud

What if you could protect the foundation of Europe’s first Super App?

Rebell is building something Europe has never had before: a

Super App .
Think of it as the one app that brings everyone together — a single gateway where people can shop, pay, book, connect, and manage their daily lives, without switching between dozens of apps.

In Asia, super apps like Alipay and WeChat have already transformed the way hundreds of millions of people live and interact. Now, for the first time, Europe is about to experience its own super app.

This is not a concept. Rebell is already funded and staffed with leaders from Alipay, SIX Payment Services, Scalapay, and Credit Suisse, preparing for a launch in 2026.

We are now hiring a

Head of Fraud

to build and lead the strategy, tooling, and operations that protect our ecosystem against fraud and financial crime.
You’ll be the guardian of trust — designing the systems, processes, and intelligence that keep our users, merchants, and business safe.

As a

Head of Fraud , you will

define and execute Rebell’s fraud prevention and risk management strategy

— ensuring that our growth and innovation are built on security and resilience.
You will own the strategy for fraud detection, prevention, and dispute management, with a strong focus on

card fraud, chargebacks, and transaction monitoring

— the most critical operational risks for our business.

This is a founding role : you will design our fraud engine, build the playbooks, select the tools, and shape a team that scales across Europe.
Your goal is to protect millions of users — without ever compromising the seamless experience that defines a true super app.

Your responsibilities

1. Fraud detection & prevention
Monitor and analyze user behavior across payments, wallet top-ups, P2P transfers, withdrawals, and card usage.
Detect fraud patterns: phishing, stolen card abuse, identity theft, mule accounts, internal collusion.
Design and implement dynamic rules (risk scoring, velocity thresholds, device fingerprinting, IP reputation, etc.).
Balance automation and human oversight — ensuring we stay ahead of new fraud typologies without slowing down user experience.

2. Disputes & chargebacks
Own the end-to-end process of disputes and chargebacks, ensuring rapid resolution and minimal financial impact.
Define policies and playbooks to prevent abuse while protecting customers.
Collaborate closely with Product and Customer Support to embed prevention mechanisms directly into the user journey.

3. Tooling & automation
Configure, calibrate, and optimize fraud detection tools.
Partner with Product & Engineering to embed fraud controls directly into the platform.
Scale real-time monitoring and alert systems to manage millions of transactions.

4. Incident response & investigations
Lead investigations into suspicious behavior or confirmed fraud cases.
Take swift action: block accounts, freeze funds, contain losses.
Coordinate with Ops and Customer Support to manage client impact and recovery.
Build a clear incident-response framework to ensure fast, coordinated action under pressure.

5. Collaboration with Compliance / MLRO
Work closely with Compliance on overlapping fraud-AML cases.
Contribute to AML scenarios involving account takeover, synthetic identities, or unusual transaction flows.
Help design internal controls and reporting frameworks aligned with EMI regulatory requirements (Banca d’Italia).

6. KPI tracking & risk reporting
Own fraud-related KPIs: fraud rate, chargeback rate, loss rate, false positives, detection time.
Maintain detailed incident logs and remediation actions.
Contribute to internal and external reporting (risk committee, regulator prep, audits).
