Lead AI Engineer Intelligence & Protection

• Build intelligence that hits hard on financial crime
• Sydney or Melbourne Based / Hybrid Working

Time to make real impact and protect our customers!

Join AI Services as the hands-on technical leader for a major Financial Crime Protection intelligence solution.

You will bring deep Financial Crime Protection domain expertise and build and guide complete products across governed data backend services APIs AI and accessible review experiences.

Importantly you will set solution-level directions while staying close to design code testing and production support. The systems you lead will support authorised decisions without making fraud AML employee customer or operational decisions.

How you will help beat the bad guys

• Lead a major Financial Crime Protection intelligence solution from intent through design build verification release and operation.
• Bring Financial Crime Protection domain-SME thinking into engineering decisions translating complex fraud AML and protection needs into safe practical production outcomes.
• Set clear boundaries between signals investigation human decisions and actions in other systems.
• Create traceable contracts across source data events entities facts signals models agents reviews and downstream systems.
• Ensure missing stale denied incomplete and unavailable information is reported honestly.
• Enforce agent controls outside the model with approved bounded tools access controls and safe action boundaries.
• Protect sensitive and Highly Protected data through least privilege minimisation pseudonymisation and controlled disclosure.
• Lead versioned and reversible releases for data contracts models embeddings APIs and workflows with tested rollback and recovery.
• Mentor engineers and turn specialist delivery lessons into reusable patterns.

Key Ingredients for Success

• Deep Financial Crime Protection domain-SME experience with strong practical knowledge of fraud AML investigations intelligence workflows controls and human decision-making in a complex regulated environment.
• Expert full-stack engineering across backend services APIs data stores and modern web applications with relevant technologies including Go or Python SQL TypeScript React and .
• Strong API event dataflow and service-boundary design including identity entitlements state audit and recovery.
• Strong data graph and investigation engineering covering lineage time quality entity resolution bounded traversal and purpose-based access.
