You provide technical authority on Entra ID readiness, identity conflict remediation, access impacts and Exchange‑related sequencing considerations that shape wave delivery. You act as the escalation point for identity and messaging blockers and maintain repeatable runbooks for remediation so that Scale squads can cut over with confidence and the Factory can execute at pace.

Good‑to‑Have: - Familiarity with tenant‑to‑tenant tooling approaches for directory and mailbox workloads (Quest‑style models). - Microsoft certification alignment in identity/security/admin domains (or equivalent experience). - PowerShell/Graph scripting for readiness checks, reporting and bulk remediation tasks. - Experience in regulated environments requiring strict audit evidence. Interpersonal & Consulting Skills: - Calm, structured escalation leader under high user‑impact pressure. - Strong risk articulation and stakeholder translation (impact, options, recommendations). - Collaborative approach with endpoints, apps, shared data and security teams. - Strong coaching behaviours: creates repeatable fixes, not one‑off heroics. - High integrity with access and security practices. - Clear written comms: tickets, handovers, remediation playbooks.
