Challenge optimism bias and escalate early when delivery is at risk. Multi-Supplier & Team Leadership Coordinate delivery across multiple suppliers and internal teams, ensuring clear ownership and zero gaps. Enable engineering teams by removing blockers rather than adding process drag. Foster a delivery culture that values predictability, quality, and operational readiness. Agile, Lean & Assurance Alignment Apply Agile pragmatically using Scrum, Kanban, or hybrid approaches as appropriate.

Confident communicator who can challenge senior stakeholders constructively. Experience working under security, compliance, and regulatory constraints. D esirable Experience Experience delivering or operating core cloud, shared platforms, or landing zones. Familiarity with public sector governance, GDS assessments, or cross-government platforms. Exposure to FinOps, platform reliability, or live service operations. Experience supporting migration programmes or large-scale onboarding. Behaviours & Ways of Working Outcome-focused: you care about what lands, not what was attempted. Comfortable with ambiguity and capable of bringing order without bureaucracy. Calm under pressure; credible when things go wrong. Willing to say "this won't land" early and back it up with evidence. What Success Looks Like Delivery plans are credible, visible, and trusted. Risks are surfaced early and actively mitigated. Suppliers deliver outcomes, not excuses. Core Cloud services land predictably and are operable from day one. Senior stakeholders trust your reporting even when the news isn't good.
