- Contribute to technology strategy (build/buy, cloud/on-prem) and IT operating-model changes that improve the business of IT.
- Guide teams on reliability, security, compliance and cost; partner with TMOs on release governance and controls.
- Shape and deliver scalable, resilient, end-to-end solutions, ensuring designs are fully considered, robust and aligned to agreed architectural standards.
- Act as the conduit between business and technology functions; translate outcomes into clear design options and actionable plans.
- Provide high-quality guidance and documentation to enable a rapid, secure path from design to build/run.
- Contribute to business development: shape proposals, provide solution credibility in pursuits, and support mobilisation of wins.
- Develop people and communities of practice; coach junior colleagues and embed reusable patterns, assets and playbooks.
