Overview

Microsoft Security Operations Centre (SOC) Analyst – T2 & T3 (Security Clearance Required). Preferred

Location:

Newcastle.

The SOC Analyst Team operates as a next‑generation, intelligence‑led Security Operations function, delivering 24×7 security monitoring and response. All SOC analysts participate in a 24×7 shift model to ensure uninterrupted service coverage, while contributing to detection improvement, automation feedback, and service optimisation when operational demand allows.

Tier 2 SOC Analysts represent the primary human analysis function, responsible for investigating escalated alerts and incidents that require human judgement, contextual understanding, and analytical depth.

• Perform deep investigation of escalated alerts and incidents from automated Tier 1 workflows.
• Validate threats, scope impact, and determine severity using contextual analysis.
• Investigate across multiple data sources, including SIEM, EDR / XDR, identity and authentication telemetry, cloud and SaaS platforms.
• Coordinate and execute response actions in line with defined playbooks, client‑specific requirements, and incident response procedures.
• Maintain clear, high‑quality investigation documentation and handover notes.

• Operate as part of a 24×7 shift rota.
• Maintain accountability for investigation accuracy and quality.
• Escalate complex or ambiguous cases to Tier 3 appropriately.
• Provide structured feedback into detection tuning, alert quality improvements, automation optimisation, and continuous improvement.

When operational demand allows, Tier 2 analysts are expected to contribute insight time to platform improvement activities, supporting the Platform Automation Lead through:

• Identification of repeatable investigation patterns.
• Feedback on automation opportunities.
• Playbook refinement and improvement; detection logic tuning recommendations.

Tier 3 analysts provide advanced security expertise and escalation handling, focusing on complex, high‑risk, or ambiguous security incidents and ensuring consistent investigation quality across the SOC.

• Handle escalations involving high‑impact or business‑critical incidents, advanced or evasive attacker techniques, and ambiguous or novel threat behaviour.
• Conduct advanced threat analysis, including attacker behaviour and intent assessment, cross‑incident correlation, and campaign/intrusion analysis.
• Provide oversight and quality assurance of Tier 2 investigations.
• Lead complex incident response coordination where required.

• Participate in 24×7 escalation coverage, via on‑call or senior shift roles.
• Act as a technical mentor to Tier 2 analysts.
• Support analyst development through coaching and investigative guidance.
• Set investigation and response quality standards across the SOC.

Like Tier 2, Tier 3 analysts provide structured feedback into platform and automation initiatives, working with the Platform Automation Lead to:

• Improve detection fidelity.
• Reduce repeat incident patterns.
• Increase automation coverage over time.
• Ensure complex incidents inform long‑term service improvement.
