What Youll Be Doing

Were looking for a Senior/Lead Card Fraud Data Analyst/ Analytics Managerto join our Fraud team. This is a hands-on high-ownership role - youll take direct responsibility for our fraud systems end-to-end from onboarding fraud through to card fraud and play a central part in building the capabilities we need as we launch new products.

  • Write complex SQL queries to interrogate transaction and customer data identify fraud signals and surface emerging attack patterns.
  • Design and build fraud detection rules from scratch set thresholds based on data and iterate based on live performance.
  • Own rules end-to-end. You spot the pattern you build the detection you monitor the outcome.
  • Work across card and lending data to understand how our customers behave and where fraud risk sits in our specific product set.
  • Contribute to fraud strategy as the team grows including input into ML-based detection further down the line.

Were Looking For

  • A strong data analyst background in a fintech or digital lending environment. You know what SMB or consumer transaction data looks like and youre comfortable. working with messy high-volume datasets.
  • SQL you can actually use. CTEs window functions the difference between WHERE and HAVING. Youll be tested on this at case study stage.
  • A genuine builder instinct. You dont wait to be told theres a problem. You find it in the data and you fix it.
  • Experience working end-to-end on analytical problems. Not handing logic to a tech team. You own it through to deployment.
  • Comfortable in a small fast-moving team where the answer isnt always obvious and you have to work it out yourself.

Nice to have

  • Direct experience working in card fraud - ideally within a bank card issuer or fintech operating on the issuing side.
  • Hands-on familiarity with card fraud systems and the data that comes with them (Visa fraud platforms CNP fraud 3DS/SCA PSD2 compliance)
