What is the opportunity?
At Westpac, we’re building responsible, human-centred AI at enterprise scale — and we’re looking for hands-on AI Engineers who can turn ideas into secure, scalable, production-ready solutions.
You’ll join our Data, Digital & AI function and work with the Westpac Chief AI Innovation Office to build practical AI capability across technology, data, risk, security, product and business teams.
This is an engineering-first role for people who can design, code, integrate, test and operationalise AI applications, services, agents and platforms — beyond proofs of concept.
You’ll bring strong software engineering fundamentals, practical AI/ML experience and the judgement to deliver safely in a complex, regulated enterprise environment.
Key Responsibilities –
- Design, build and ship production-ready AI applications, services, agents and internal tools.
- Integrate foundation models, ML models, RAG, vector stores and AI services into secure enterprise workflows.
- Build pipelines for prompt management, model invocation, grounding, validation and evaluation.
- Embed security, privacy, compliance, model risk and responsible AI guardrails from design to delivery.
- Build testing, evaluation, monitoring, and feedback loops for quality, performance, safety, and cost.
- Optimise latency, reliability, and cost across AI workloads.
- Collaborate with product, data, risk, security, and platform teams to clarify requirements, surface trade-offs, and align priorities for delivery.
Essential Ingredients …
- Hands-on AI engineering experience in large, complex corporate or regulated environments.
- Ability to deal effectively with technical and non-technical stakeholders at all levels.
- Tertiary qualifications in a relevant technology, engineering, computer science, data or related discipline, or equivalent practical experience.
- Strong software engineering background across backend services, APIs and production systems.
- Practical experience operationalising LLM, ML or AI services beyond prototypes or academic projects.
- Hands-on knowledge of RAG, embeddings, vector databases, orchestration and model evaluation.
- Experience with cloud, CI/CD, automated testing, observability and enterprise release practices.
- Understanding of prompt design, evaluation, safety testing and responsible AI practices.
- Ability to balance experimentation speed with engineering quality and safety.
- Comfortable working with diverse stakeholders to triage requests, communicate constraints, and prioritise work based on impact and risk.
