About this role
Alexander Barnes is partnered with a high-growth regulated fintech who are rapidly growing their Financial Crime Operations function.
What you will do
As a Senior Fraud Investigator, you will be a key contributor to the business's fraud operations, personally owning and investigating the most complex fraud cases across consumer and partner fraud. You will work across a broad range of fraud typologies, handling cases with accuracy and consistency while maintaining deep operational expertise that supports the team as an internal centre of excellence. In this position, you will identify inefficiencies, escalate risks, and contribute to improving processes, tooling, and ways of working. You will collaborate with internal teams and vendor partners, validate operational changes through hands-on casework, and share insights that strengthen fraud prevention, detection, and investigation strategies.
Who you are
- At least 5 years of experience working on the most complex fraud investigations, within fintech or retail banking
- Deep, hands-on understanding of the different typologies within fraud, across consumer and/or partner fraud
- Experience handling cases end-to-end with a high level of accuracy and consistency
- Ability to identify operational gaps, inconsistencies, and risks, and proactively raise them
- Experience working with fraud tooling and case management systems across automated and manual workflows
- Analytical mindset, with the ability to identify patterns and translate them into actionable insights
- Clear communicator, able to document processes, decision rationale, and share insights with stakeholders
- Self-directed and reliable, with the ability to manage workload and adapt in a fast-changing environment
Awesome to have
- Experience working with outsourced vendor operations, including quality monitoring and feedback loops
- Experience contributing to SOP creation, maintenance, and operational documentation
- Experience participating in calibrations, quality checks, or training initiatives
- Exposure to cross-functional collaboration with product, compliance, or risk teams
- Relevant certification such as CFE (Certified Fraud Examiner) or equivalent
Why apply
You'll be joining at a pivotal point in that build-out, with real scope to shape how the function operates rather than simply executing against an already-fixed process. There's a clear path for career progression as the team scales, a strong, collaborative culture, and a competitive package including a performance-based bonus. If you want to move beyond routine casework and work on the kind of complex, high-value investigations that actually test your expertise, this is a rare opportunity to do that at genuine scale.
