- Embed security and compliance standards into all platform components, ensuring auditability, policy enforcement, and alignment with enterprise governance requirements.
- Drive developer experience improvements through platform standardisation, self‑service tooling, templates, and AI‑enabled capabilities (e.g. Copilot, intelligent automation).
- Collaborate with Architecture, Cloud COE, SRE, and engineering teams to deliver consistent and governed platform capabilities across the organisation.
- Mentor junior engineers and contribute to technical leadership, standards definition, and engineering best practices.
