Fraud Analyst

London, England, United Kingdom – £30,000‑£45,000

Job Description

This is an exciting opportunity to join UNiDAYS as a Fraud Analyst and play a key role in protecting our platform, members, and partners from evolving threats. You’ll tackle complex analytical challenges, uncover fraud patterns, and help strengthen our defences against abuse. We\’re looking for an experienced analyst with a strong foundation in fraud to help shape and execute our fraud prevention posture. This position represents a significant opportunity for career growth and to deepen your specialisation in a hands‑on role. Our team uniquely combines the disciplines of cyber security and fraud prevention, using many similar tools, techniques and approaches to stop attackers. While your day‑to‑day focus will be on fraud analysis and prevention, you’ll also occasionally contribute to security operations as part of our team rotation, giving you exposure across both areas and the opportunity to grow as a threat analyst. You’ll work closely with stakeholders across Engineering, Product, Customer Support, and Partner facing teams to ensure that fraud considerations are built into our systems. You will also identify fraud trends that will enable us to drive improvements and foster a culture of fraud awareness and threat prevention across the business.

Personal

Job Responsibilities
