Senior FinCrime Ops Manager in London

LemFi (Series B) is building the go-to financial app for the Global South. Moving to a new country shouldn’t mean starting from zero. That's why our team of 400+ spanning 20+ countries is building a financial ecosystem that helps immigrants stay connected to home, build stability, and create wealth regardless of where they are from or where they live. What began as fast, affordable remittances is now evolving into a complete platform for multi-currency accounts, payments, credit, and long-term financial growth. With millions of users across the globe, we process over $1B in monthly transactions to 30+ countries, proving that borders shouldn't limit financial opportunity.

About the role

You'll own and run LemFi's Financial Crime Operations, sitting at the heart of how we protect customers while keeping the product fast, accessible, and fair. This is hands-on operations leadership. You're accountable for live decisioning, investigations, unblocks, and the continuous improvement of in-life controls. You'll manage a team of 20-30 analysts, and you'll design, run, and improve an operation that balances fraud prevention, customer experience, and growth in a high-volume, fast-moving environment. You won't just manage queues. You'll think like an operator, move like a business owner, and build a team that makes consistent, risk-based decisions at scale.

What you'll build and own

• Lead the day-to-day Financial Crime Operations function. Own investigations, unblocks and fraud decisioning for in-life customers, and set the standard for how work flows through the operation.
• Own operational outcomes: time-to-unblock, investigation turnaround, throughput, decision quality, and SLA performance as volumes scale.
• Continuously assess and improve operational controls to reduce false positives and unnecessary friction. Use real operational insight, not just design-on-paper thinking.
• Partner with Product and Data to refine rules, unblock logic, and experiments that improve conversion while maintaining risk standards.
• Manage and mentor a team of 20-30 Financial Crime analysts. Build a culture of ownership, sound judgement, and customer awareness.
• Monitor trends in alerts, unblocks, false positives and investigation outcomes. Translate data into practical operational changes that improve speed, quality and customer outcomes.
• Collaborate with Compliance and the MLRO on escalations, SARs and regulatory matters. Act as the operational voice in discussions around risk, controls, and regulatory expectations.

Your experience

• 6+ years in Fraud or Financial Crime Operations, with at least 3 years in a leadership role.
• Strong experience managing live investigations, unblocks, alerts and decisioning in a fintech or high-volume financial environment.
• Proven ability to run and improve operational workflows, SLAs and performance metrics.
• Experience partnering closely with Product, Data or Engineering teams on control performance and operational improvements.
• Solid analytical capability (Excel or similar tools) to assess trends and operational effectiveness.
• Leadership experience managing and developing teams at scale.

Nice to have

• Experience working with machine learning or rules-based decisioning systems.
• Cross-border financial operations experience.
