Design and architect scalable AI solutions
Solve high-value, real-world challenges
Own technical problem-solving end-to-end

We’re looking for a Principal AI Scientist to lead the design, development and deployment of advanced AI solutions that deliver meaningful business impact.

This is a senior technical role within our AI capability. You will have the opportunity to own end-to-end solution design and guide teams to deliver high-quality, production-grade AI outcomes.

Our people are customer obsessed. They prioritise the needs and satisfaction of the customer above all else. Our mindset fosters innovation and creates strong, lasting customer relationships as we strive to be the most customer centric company in Australia and New Zealand.

In the role of Principal AI Scientist, bridge the gap between cutting-edge AI capability and real-world application, setting the standard for how we build, deploy and embed AI across the enterprise.

Key Responsibilities

Lead the end-to-end solution design of agentic and broader AI systems, from problem framing through to deployment and scaling
Translate complex business problems into robust, scalable AI architectures and models
Provide technical leadership and mentorship to AI scientists and engineers, uplifting overall capability
Partner closely with stakeholders across business and technology to ensure solutions are aligned to strategic outcomes
Oversee and contribute to solution development, validation, and optimisation across areas such as machine learning, generative and agentic AI
Ensure solutions meet enterprise standards for governance, risk, and responsible AI
Drive best practice in experimentation, reproducibility, and model lifecycle management
Influence AI strategy and roadmap, identifying emerging opportunities and innovation pathways

What You Bring

Deep experience in AI/ML solution design and delivery in enterprise environments, including experience in agentic and generative AI
Proven ability to architect and deploy production-grade AI systems at scale
Expertise in relevant technical domains (e.g. machine learning, deep learning, recommendation systems, NLP, or GenAI)
Advanced programming skills in Python and experience with agentic and generative AI frameworks
Demonstrated experience mentoring and guiding high-performing technical teams
Strong communication and stakeholder engagement skills, with the ability to translate technical concepts into business value
Experience navigating model governance, risk, and responsible AI frameworks

Why This Role Matters

AI is a critical enabler of our strategic ambitions, from enhancing customer experiences to improving operational efficiency and decision-making at scale.

As a Principal AI Scientist, you will play a pivotal role in shaping how AI is designed, governed and delivered across the organisation. Your work will directly influence high-impact initiatives, ensuring solutions are not only technically sound, but scalable, responsible and aligned to business outcomes.
