Cloud Architect – M365, Identity & Zero Trust

Contract | Complex Transformation Environment

We're supporting a client delivering a major modernisation of their end-user, identity, and security platforms. The focus is on Microsoft 365 adoption, identity-led security, and a zero-trust network architecture operating at scale in a highly regulated environment.

This role suits a hands-on Cloud Architect who can operate comfortably at both strategy and delivery level, influencing design decisions while staying close to implementation.

What you'll be working on

• Designing and shaping a Microsoft 365–centric end-user and identity platform
• Defining and evolving zero-trust / SASE architecture and security controls
• Producing clear, pragmatic architecture designs (high-level through to detailed)
• Creating and maintaining core architecture artefacts (identity flows, security patterns, standards)
• Supporting delivery teams with architectural direction, challenge, and assurance
• Assessing options and trade-offs across cost, risk, resilience, and operability
• Embedding cyber security by design, including threat modelling and risk reduction
• Defining technical standards and guardrails aligned to enterprise and regulatory requirements

What we're looking for

• Proven experience as a Cloud or Enterprise Architect in complex environments
• Strong knowledge of Microsoft Cloud (M365, Azure, Entra ID, Power Platform)
• Solid understanding of identity-centric design and zero-trust networking
• Experience designing end-user compute and identity platforms at scale
• Comfortable working across multiple teams and stakeholders
• Strong analytical skills with the ability to cut through ambiguity
• Experience operating in regulated or security-conscious organisations

Nice to have

• Experience with Okta or equivalent identity platforms
• Exposure to Zscaler or similar zero-trust/SASE technologies
• Background in public sector or heavily regulated industries

Additional information

• Security Clearance (SC) required
• Hybrid working model (details discussed at screening stage)
