About the Role
Build production-ready generative and agentic AI solutions that improve customer experiences, solve complex technical challenges using modern AI models, retrieval systems and evaluation methods, and help shape the safe, responsible and scalable use of AI across CommBank.
Responsibilities
- Build and evaluate generative AI solutions, including retrieval-augmented generation, conversational assistants and colleague drafting tools
- Design agentic workflows that plan, use approved tools and complete multi-step tasks with appropriate permissions and human oversight
- Engineer prompts, system instructions and retrieval pipelines to improve grounding and response quality
- Create evaluation harnesses and golden datasets covering groundedness, accuracy, task completion, latency and cost
- Select and tune models for different use cases, balancing quality, cost, latency and data-residency requirements
- Apply responsible AI controls, including hallucination mitigation, prompt-injection testing, personal-information handling and risk-review evidence
- Work with engineering colleagues to deploy and monitor solutions, including guardrails, telemetry and drift detection
Requirements
- A tertiary qualification in data science, statistics, computer science, engineering or another quantitative discipline, or equivalent demonstrated experience
- Strong Python and SQL skills
- Practical experience with large language model and agent frameworks, vector stores and cloud AI platforms
- Experience in prompt and context engineering, retrieval design and the systematic evaluation of non-deterministic systems
- Experience delivering generative AI or machine-learning solutions into production, ideally within a regulated environment
- Knowledge of responsible AI, privacy and model-risk controls, including safety testing and guardrails
- The ability to explain model behaviour, limitations and risks to technical, non-technical and governance audiences
- Experience working in agile, cross-functional teams with engineers, product owners and designers
