• Design and evolve secure AWS landing zones aligned to government, security and compliance requirements
• Establish platform guardrails, standards and reusable patterns that enable teams to deliver safely at scale
• Lead architectural governance and design assurance, embedding Secure by Design and AWS Well-Architected principles
• Provide expert guidance across AWS compute, networking, storage, security, monitoring and platform automation
• Partner with platform engineering, cyber security and operations teams to improve observability, resilience and incident readiness
• Influence senior stakeholders on cloud strategy, investment priorities and technical risk
• Collaborate with suppliers and partners, including AWS, to align enterprise architecture with platform capability
• Mentor architects and senior engineers, strengthening cloud and platform engineering maturity
• Support the ongoing platform roadmap, ensuring the AWS estate remains scalable, resilient and future-ready
