Summary and responsibilities
Role overview
Summary
This Senior Data Analyst role focuses on transaction monitoring and fraud detection within the FinCrime team. The analyst will leverage data, SQL, and Python to enhance fraud detection, minimize false positives, and strategically prioritize high-risk cases, collaborating across fraud operations, analytics, and product teams.
Mews is looking for a Senior Transaction Monitoring Fraud Data Analyst to join our FinCrime 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 FinCrime, 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
What’s in it for you?
Our success is powered by our incredible people, supported by benefits that help them thrive.
Global benefits
No matter where you’re based, you’ll enjoy:
Unlimited paid holiday (yes, really)
Participation in our company share program
Paid parental leave (6 months fully paid for primary caregivers, 2 months for secondary, available after one year of service)
An annual Learning budget of €300 (and more for high performers) to support your development
