We are recruiting a Lead Cloud Architect to support a major cloud-transformation programme within central government. The role will lead the assessment of an existing Google Cloud Platform estate and define its future-state architecture, governance framework and target operating model.
This is a strategic architecture role focused on establishing an enterprise-scale GCP environment and transitioning its ownership between government organisations. The emphasis is on architecture, governance and operating-model design rather than hands-on engineering delivery.
Role responsibilities
- Lead the current-state assessment of the existing GCP estate, governance and operating arrangements.
- Define the target landing-zone architecture, GCP organisation hierarchy and folder structure.
- Design organisation policies, governance controls and role-based access models.
- Develop a cloud operating model covering ownership, administration, assurance and service management.
- Define the identity strategy across Cloud Identity, Workforce Identity Federation and Entra ID.
- Design security architecture aligned with Secure by Design, NCSC guidance and the Cyber Assessment Framework.
- Establish the FinOps approach, including billing hierarchies, cost controls and chargeback mechanisms.
- Define the operational transition model for transferring platform ownership and administration.
Key experience and requirements
- Extensive enterprise or lead architecture experience across large-scale GCP environments.
- Strong experience managing GCP Organisations, folder hierarchies, organisation policies and landing zones.
- Experience designing enterprise cloud-governance frameworks and target operating models.
- Strong knowledge of identity and access management, including Cloud Identity, Workforce Identity Federation and Entra ID integration.
- Experience applying Secure by Design principles, NCSC guidance and CAF requirements.
- Experience designing FinOps operating models, billing structures and chargeback approaches.
- Strong stakeholder-management skills across architecture, cyber security, operations and senior leadership.
- Active SC clearance or eligibility to obtain it; Google Professional Cloud Architect, TOGAF, CISSP or CCSP certification would be advantageous.
