Senior IDAM Architect – Identity Pillar

Senior IDAM Architect – Identity Pillar (Lot 1)
Location – Coventry, UK

Role Purpose

The Senior IDAM Architect is the ** end to end technical authority for all Identity Pillar scope under Lot 1**, accountable for Initiate, Discovery, Design, and Implementation across Identity Governance & Administration (IGA), Active Directory/Entra ID, RBAC/ABAC, PKI, Conditional Access, Identity Lifecycle, CIEM, and identity threat protection capabilities.

This role acts as the single technical point of contact for all identity related decisions, integrations, designs, and technical escalations, ensuring adherence to Zero Trust principles, Client Delivery & Cyber frameworks, and the architectural governance process.
