Offer description

.

These days, we’re still just as much a family as we always have been. We have tons of integrity, we’re enthusiastic. we’re competitive and we just get it done – whatever the challenge.

We’re looking for a Microsoft & Security Infrastructure Administrator who loves building things properly. This role sits at the heart of our cybersecurity strategy, taking a clear security vision and engineering it into a scalable, automated Microsoft cloud platform that’s secure by design. It’s a hands-on, high-impact role with real ownership and influence

Reporting To: Head of Cybersecurity (Accountable)
Role Status: Technical Lead (Responsible)
Mission: To translate strategic vision into a scalable, "secure-by-design" technical reality using modern Microsoft cloud principles

YOUR PURPOSE

1. Vision to Reality: While the Head of Cybersecurity defines the "Why" and "Vision," this role defines the technical "What" and engineers the "How."
2. Scalability First: Move from case-by-case, reactive fixes to a fully automated, policy-driven management-at-scale model.

KEY OUTCOMES FOR SUCCESS:

3. Scalable Infrastructure: Transition from ad-hoc management to a fully automated, policy-driven environment.
4. Proactive Security: Remediating security gaps before they are exploited, with a focus on long-term stability.
5. Metrics-Driven Operations: Establishing a regular cadence of high-signal reporting on platform health and risk reduction.
6. Zero-Touch Operations: Fully operational, secure automated provisioning reducing manual intervention.

ESSENTIAL RESPONSIBILITIES:

7. Identity, Access & Segregation (EntraID): Optimising structure via Administrative Units and enforcing strict segregation of duties.
8. Endpoint Security & Device Management (Intune): Configuring MDM/MAM and automated deployment for all device types.
9. Platform Hardening & Security Baselines: Implementing "Secure-by-Design" baselines across the M stack, including Copilot.
10. Azure Tenant & Modern Cloud Governance: Enforcing Data Residency, Zero Trust principles, and Infrastructure as Code (Terraform).
11. SharePoint & Collaboration Governance: Technical delivery of site life cycles and external sharing controls.
12. Compliance, Audit & Documentation: Maintaining technical standards and "code-based" evidence for audit readiness.
13. Reporting, Analytics & Metrics: Defining and delivering KPIs to measure implementation effectiveness and platform health.

THE IDEAL CANDIDATE:

14. Proactive Solution-Finder: Prioritises long-term system integrity over short-term fixes.
15. Data-Driven & Analytical: Defines success through measurable KPIs and clear executive reporting.
16. Modern Cloud Mentality: Committed to staying current with Microsoft’s evolving cloud and AI landscape.
