About the Opportunity
This is a newly created role within a growing fraud analytics team that’s gaining real traction across the business. The team has expanded significantly over the past year and continues to invest in building out its data science capability.
You’ll be joining a collaborative, Wellington-based team of 17 that works across a mix of exploratory projects, tool development, and investigation support. The work is varied and interesting, from building models to identify unusual patterns, through to supporting deeper investigations that can feed into real world outcomes.
  • Build and develop models to detect fraud and unusual behaviour
  • Work across exploratory, development, and investigation-focused work
  • Collaborate closely with analysts, intelligence teams, and stakeholders
  • Contribute to a team that values knowledge sharing and continuous improvement
  • Mentor junior team members and support technical development

What You’ll Bring
We’re looking for a hands-on data scientist who enjoys working with complex datasets and turning them into something meaningful. This role suits someone who is technically strong but also collaborative and open to sharing knowledge with others.
  • Strong SQL skills – this is core to the role
  • Experience with Python and applying data science techniques
  • Proven ability to build and apply models to real-world problems
  • Comfortable working with messy, complex data
  • Strong communication skills and ability to explain insights clearly
  • Interest in fraud, risk, or behavioural data (experience is a bonus, not essential)
  • A team mindset, with willingness to mentor and support others

What’s on Offer
Alongside interesting and meaningful work, you’ll be joining a genuinely supportive and engaged team environment.
  • Opportunity to work on high-impact fraud detection work and learn
  • A growing team with clear investment and direction
  • Hybrid working (2 days in office, flexibility offered)
  • Strong benefits package
  • A collaborative, social team culture based in Wellington
