We’re looking for a hands‑on Security Engineer to join a leading organisation undergoing a major merger. This is a 12‑month fixed‑term contract paying £70,000, offering full remote flexibility across the UK.

The Opportunity

You’ll play a key role in stabilising and strengthening Microsoft 365 and Azure environments through a period of change. The role blends technical delivery with stakeholder engagement – you’ll be as comfortable securing systems as you are guiding users through new policies and controls.

What You’ll Be Doing

• Delivering and maintaining security across Microsoft 365 and Azure.
• Building and tuning detections in Microsoft Sentinel.
• Managing patching, malware protection, and vulnerability remediation.
• Supporting Cyber Essentials Plus and ongoing compliance programmes.
• Documenting changes, maintaining governance, and ensuring minimal disruption.
• Mentoring a service desk engineer stepping into cyber security.

What You’ll Bring

• Strong experience with Microsoft 365 security, Defender, Intune, and Azure AD/Entra ID.
• Working knowledge of Azure Sentinel (SIEM) and KQL.
• Solid understanding of patch management and endpoint security.
• Previous involvement in Cyber Essentials Plus or ISO27001 accreditation.
• Clear communication skills, able to engage technical and non-technical stakeholders.

Why Join

You’ll be stepping into a critical transformation phase where your input genuinely shapes the business. It’s a chance to deliver high‑impact work, develop new skills, and contribute to building a scalable security foundation for future growth.
