Security Architect - Microsoft Security

Our client is a global network and communications provider.

Our client provides network, voice and data centre services to thousands of businesses around the world, allowing them to focus on delivering their business goals instead of the underlying infrastructure.

We are looking for a Security Architect specialising in the Microsoft Security platform (M365 E5) to join the Security and Resilience – Security Architecture team.

This role acts as the design authority and subject matter expert for Microsoft security technologies, including Defender, Entra ID and Purview, and will play a key role in modernising our client's security posture.

The role combines:

• Deep technical ownership of the Microsoft Security stack (E5)
• Security design, architecture and assurance
• Strategic transformation across our client technology domains

You will play a critical role in driving:

• Identity-driven and endpoint-focused security architecture for user-facing environments
• Data protection and compliance capabilities through Microsoft Purview
