This is a fantastic opportunity to join a fast-paced, growing bank with a reputation for doing things differently. We don't want another cog in the machine—we're looking for self-starters and bold thinkers who want to pave their own career paths and are passionate about building and protecting the financial infrastructure that powers the UK's best and brightest businesses.

In a nutshell, the mission of a Technical AML / Fraud Lead is to spearhead the development and optimisation of rule-based fraud detection systems—primarily in Feedzai—by designing scalable, proactive, and data-driven frameworks that secure the bank while enabling growth.

• Identify inefficiencies and propose scalable improvements across current AML, Sanctions, and Fraud detection logic.
• Assess existing toolsets and proactively identify opportunities for improvement in financial crime prevention architecture.
• Build and evolve the Management Information (MI) Framework to ensure real-time visibility and continuous improvement of fraud risk metrics.
• Upskill and mentor colleagues to expand technical capabilities and fraud detection best practices across the team.
• Leverage GenAI tools to increase productivity and enhance rule design, simulation, and decision-making processes.

Requirements:

• 5-7 years of experience in Fraud, AML, and Sanctions transaction monitoring within financial services.
• Hands-on experience configuring Feedzai or equivalent AML, Fraud, and Sanctions Transaction Monitoring and Payment Screening tools in a business banking setting.
• Strong technical foundation: proficient in Python and SQL for data modelling and rule implementation.
• Proven track record of implementing Fraud and AML strategies that deliver measurable risk reduction.
• Sound understanding of regulatory and compliance frameworks related to financial crime.
• Strong analytical, problem-solving, and communication skills.
• Previous experience in team leadership or technical mentoring roles.
