About the role

First things first: you want to know what you're actually applying for. It's impossible to capture every nuance of a role - especially at a rapidly growing company like Mews - but if we had to distill it down to a job description (which we do because this is a job description), it would be this:

Mews is looking for a Senior Transaction Monitoring Fraud Data Analyst to join our Fin Crime team within Fintech.

This is a high-impact role for someone who can use data to improve fraud detection, reduce false positives, and help the team focus on the cases that matter most. You'll work at the intersection of fraud operations, analytics, and product, using SQL, Python, and strong problem solving to identify patterns, improve rules, and support better decision making.

We're looking for someone who is hands-on, curious, and comfortable working in a fast-moving environment where not everything is perfectly defined. This is not a reporting role. We need someone who can dig into the data, spot what is going wrong, and recommend practical actions that improve outcomes.

Your mission, should you choose to accept it:

* Analyse transaction monitoring and fraud rule performance to identify gaps, inefficiencies, and opportunities to improve detection

* Investigate trends, anomalies, and behavioural patterns across transactions, properties, and customer activity

* Help improve how we prioritise cases by risk, with the goal of reducing manual review volumes and increasing focus on high-risk activity

* Partner closely with Fin Crime, Product, Compliance, and Data teams to improve controls and bring in new data sources

* Work with data engineers and other technical teams to support better pipelines, data quality checks, and more reliable monitoring inputs

* Support the development of internal scoring approaches and future machine learning use cases as the function evolves

* Translate complex analysis into clear recommendations that improve fraud prevention while minimising friction for legitimate customers

Your mission, should you choose to accept it:

* Own and run the ERM framework and risk appetite for Mews FS, including risk assessments, stress testing and Board reporting.

* Provide independent risk oversight on new products, major changes and strategic initiatives, and act as a key contact for DNB and other regulators on risk matters.

* Design and maintain a fit-for-purpose internal control framework and key controls across payments, safeguarding, liquidity, ICT, outsourcing and incident management.

* Lead risk-based testing, monitoring and follow-up on incidents, control weaknesses and audit findings.

* Provide pragmatic, business-oriented risk advice that keeps us compliant while enabling product and commercial teams to ship at pace.

* Build a strong risk culture through training, guidance and clear, plain-language communication across the organisation.

️ You'll be a great fit if you bring a few of the below with you:

Must-have experience

* Strong experience in fraud detection or transaction monitoring analytics

* Proven ability to improve rules, controls, or detection logic using data

* Advanced SQL skills

* Strong Python skills

* Experience working with large datasets to identify patterns, outliers, and risk signals

* Ability to move from analysis to action, not just reporting findings

* Confidence working cross-functionally with operational, technical, and compliance stakeholders

We'd be especially interested in candidates from:

* fintech

* payments

* buy now pay later

* e-commerce

* transaction monitoring or fraud solution providers
