Context
We are a factoring company currently structuring our Risk function. Our core business is providing financing through API integrations, primarily for receivables generated by marketplaces and SaaS platforms.
We are running a BNPL pilot, which introduces a materially different fraud exposure compared to our existing portfolio.
This mission takes place during a transition period: We are recruiting a Head of Risk and a Fraud Risk Analyst. The freelance engagement is designed to lay the foundations before the permanent team is in place.The freelance engagement is designed to both lay the foundations and actively own the fraud risk function until the permanent team is in place.
The Role
Own and build the fraud prevention function from scratch — combining hands-on operational ownership with structured framework delivery. The goal is not to produce a handover pack and step away, but to run the function in practice while building the tools and documentation the incoming team will inherit.
Deliverables
Four deliverables, sequenced logically:
- Fraud typology mapping relevant to our business model — supplier fraud, document fraud, identity fraud, collusion, flow manipulation — covering factoring, BNPL and marketplace/SaaS receivables
- Fraud risk matrix across the full transaction lifecycle: onboarding, credit assessment, financing, repayment
- Control gap analysis with prioritized recommendations by risk level
- Operational roadmap for Risk, Data, Product and Operations — concrete actions, not principles
- Each deliverable must be directly usable by internal teams. The objective is a working tool, not a report.
Scope of ownership
Beyond framework delivery, the freelance is expected to actively carry the fraud risk function during the mission period.
This includes:
- Owning fraud monitoring and triage on live flows
- Acting as the internal point of contact for fraud-related questions across Risk, Product, Data and Ops
- Making operational decisions within agreed escalation thresholds
- Feeding real cases and signals back into the framework as it is built
The Project team
- Product Team
- General Counsel and Risk Team
- Data Team
- Ops Team
