• Influence company-wide strategy, helping executives and technical leaders make informed trade-offs in capability development and delivery sequencing.

Requirements

• 15+ years of experience in software, data, or AI engineering, including extensive hands-on experience designing and deploying production-scale AI systems.
• Proven success leading and delivering AI initiatives that bridge innovation and pragmatic business impact.
• Deep understanding of transformer architectures, LLMs, and AI agent frameworks, and practical experience orchestrating them in enterprise-grade systems.
• Proficiency in Python, PyTorch, and modern MLOps/AIOps ecosystems (e.g., LangChain, Ray, Kubeflow, MLflow, Hugging Face).
• Strong foundation in data management, IAM, governance, and security, with experience embedding these principles into AI lifecycle workflows.
• Expertise in distributed systems, Kubernetes, and GPU orchestration at scale.
• Ability to connect engineering initiatives to business outcomes, translating complex AI concepts into actionable strategic roadmaps.
• Demonstrated systems-level thinking — designing architectures that are scalable, interoperable, and measurable.
• Commitment to observability, metrics, and data-driven decision-making to guide prioritisation and continuous improvement.
• Excellent communicator and collaborator, able to influence across technical and executive teams.

Preferred Qualifications

• Experience as a principal, architect, or head of AI in a complex or fast-scaling environment.
