Senior Fraud Investigator in Glasgow

As a Senior Fraud Investigator, you will support Nationwide’s ambition to deliver fair, trusted and customer-focused banking, in line with its mutual purpose and strategic drivers. Working within a specialist investigations team, you will conduct root cause analysis of complex high value fraud and support with sensitive or high-profile investigations to help protect customers, uphold the Society’s commitment to doing the right thing, and ensure risks are managed effectively.

You will play a key role in maintaining a safe and well-controlled environment, ensuring fraud risks are identified, assessed and addressed in line with regulatory and governance expectations.

You’ll help us strengthen trust by identifying root causes, influencing control improvements, and embedding lessons learned across the organisation. Through collaboration with operational teams, legal partners and external agencies, you will actively contribute to strengthening controls and improving how the Society responds to fraud.

Working across operational, business, risk and legal teams, you will help ensure that risks are clearly understood, mitigated and reported appropriately, supporting Nationwide’s focus on customer value, trust and long-term sustainability.

At Nationwide we offer hybrid working wherever possible. More rewarding relationships are supported through our hybrid approach, bringing colleagues together across our UK wide estate, whilst also supporting generous access to home working. We value our time in the office to solve problems, to learn, and to feel connected.

For this job you'll be located at our nearest regional office or hub. There will be a need to regularly connect with colleagues for collaboration and in some locations you’ll be expected to spend at least two days a week, or if part time you'll spend 40% of your working time, in the office. If your application is successful, your hiring manager will provide further details on how this works.

If we receive a high volume of relevant applications, we may close the advert earlier than the advertised date, so please apply as soon as you can.

What you’ll be doing

You will undertake complex fraud investigations to ensure customers are treated fairly and outcomes are evidence-based, supporting Nationwide’s focus on delivering strong customer outcomes and maintaining trust. You’ll work across teams to gather evidence, challenge assumptions and build a clear understanding of events, ensuring every decision is grounded in facts and aligned to both regulatory expectations and customer fairness.

You will translate investigation findings into clear insight, identifying root causes and control weaknesses to support improvements across the control environment and reduce future risk exposure and customer harm at the earliest opportunity. You will also contribute to governance by producing structured written outputs that support risk reporting and decision-making.

You will gather actionable intelligence and leads to engage with law enforcement and legal representatives, providing evidence in line with required evidential standards.

You will remain aware of changes in fraud risk and the wider environment, ensuring emerging risks are identified and understood, and that investigation activity continues to align with regulatory expectations and Nationwide’s commitment to doing business responsibly.
