Jobbeschreibung

Senior SecOps Engineer - Microsoft Security

UK | Predominantly Remote | Occasional presence in London

Permanent

We are partnering with a specialist Microsoft Security organisation looking to appoint two highly experienced Senior SecOps Engineers to its growing Microsoft Cyber Engineering team.

This is not a traditional SOC Analyst position.

We are looking for technically strong Microsoft Security Engineers with genuine hands‑on experience designing, implementing, engineering and optimising Microsoft Sentinel and Defender solutions within enterprise customer environments.

The organisation works extensively across the Microsoft Security portfolio and is looking for individuals who can bring significant technical depth while remaining hands‑on with complex customer environments.

The Role

Working alongside Security Engineers, SOC Analysts and wider delivery teams, you will take responsibility for the implementation, optimisation and ongoing improvement of Microsoft security solutions.

Responsibilities will include:

• Design, implementation and support of Microsoft Sentinel and Microsoft Defender / Defender XDR
• Engineering and optimisation of SIEM capabilities across enterprise environments
• Developing and tuning KQL queries, analytics and detection rules
• Designing and implementing SOC automation, playbooks and scripting
• Improving security event detection and response capabilities
• Conducting Microsoft tenant health checks, security audits and architecture reviews
• Analysing cloud security risks and recommending appropriate security controls
• Supporting complex incident triage and resolution
• Designing and documenting security engineering standards and processes
• Researching and implementing new Microsoft security capabilities
• Producing high‑quality technical and customer‑facing documentation
• Working directly with customers and technical stakeholders
• Supporting and mentoring more junior members of the engineering team

Essential Experience

To be considered, you should have strong commercial experience across the following:

• Microsoft Sentinel / Azure Sentinel
• Microsoft Defender / Defender XDR
• Strong KQL / Kusto Query Language capability
• Security Engineering, SOC Engineering or Microsoft Security Consulting
• SIEM engineering rather than solely alert monitoring or incident triage
• Detection engineering and security monitoring optimisation
• Automation, scripting, SOAR or Sentinel playbooks
• Cloud security assessments, controls and risk analysis
• Designing and documenting security processes
• Customer‑facing technical deliveryCandidates whose experience is predominantly L1/L2 SOC monitoring without hands‑on Sentinel and Defender engineering are unlikely to be suitable for this position.

Highly Desirable

Experience across any of the following would be particularly valuable:

• Microsoft Purview
• Microsoft Defender for Endpoint
• Defender for Cloud
• Defender for Identity
• Defender for Office 365
• Microsoft Entra ID
• Intune
• Azure security architecture
• Logic Apps / Sentinel playbooks
• PowerShell or Python
• MITRE ATT&CK
• Microsoft Security architecture and tenant assessmentsPrevious experience working directly for Microsoft, or within a leading Microsoft Security Partner, MSSP or specialist Microsoft consultancy, would be highly advantageous.

Microsoft Certifications

Relevant Microsoft certifications are strongly preferred, particularly:

• SC-200 - Microsoft Security Operations Analyst
• AZ-500 - Azure Security Engineer Associate
• AZ-104 - Azure Administrator Associate
• AZ-305 - Azure Solutions Architect Expert

Equivalent or additional Microsoft Security certifications will also be considered.

The Opportunity

This is an opportunity to join a highly specialised Microsoft Security environment rather than a broad IT or generalist cybersecurity function.

You'll work alongside experienced security professionals on complex customer engagements, with significant exposure to the wider Microsoft Security ecosystem and continued investment in technical training and development.

The position would particularly suit an established Microsoft Security Engineer who wants to remain technically hands‑on while taking greater ownership of solution design, engineering standards, customer environments and the development of security operations capabilities.
