Job Description:

SOC / Cyber Threat Detection Analyst - SANS/GIAC

Cyber Threat Detection Analyst

Location: Wokingham, Berkshire (On-site)
Salary: Competitive (dependent on experience) + excellent benefits & training
Security Clearance: Ideally SC Cleared or eligible for SC

Role Overview

As a Cyber Threat Detection Analyst, you will play a hands-on role within an advanced cyber defence function, focused on proactive threat hunting, adversary behaviour analysis, and high-fidelity threat detection across enterprise environments.

This role goes beyond reactive alert handling. You will actively hunt for malicious activity using telemetry, SIEM data, and threat intelligence, develop hypotheses based on MITRE ATT&CK Tactics, Techniques, and Procedures (TTPs), and support incident management and response activities when threats are identified.

We are open to experienced SOC Analysts where threat hunting, investigations, and proactive detection have formed a significant part of their role, and who are looking to further develop in a more hunting-led environment.

This position is well suited to analysts who enjoy thinking like an attacker, have worked alongside or supported red team or purple team activities, and want to deepen their expertise in threat detection and detection engineering.

Skills & Experience We're Seeking

• Experience in threat hunting, cyber threat detection, SOC, blue team, or cyber defence environments, with ideally around five years hands on experience.
• Strong hands-on experience using SIEM platforms, including:
• Microsoft Sentinel (KQL)
• Splunk (SPL)
• Elastic Security/Kibana (KQL, ESQL)
• Practical and operational understanding of MITRE ATT&CK, attacker techniques, and adversary tradecraft
• Experience working with Indicators of Compromise (IOCs) and threat intelligence feeds
• Solid experience across the security event life cycle, including detection, investigation, and incident management
• Hands-on experience with EDR/XDR technologies such as Microsoft Defender, CrowdStrike, SentinelOne, or Carbon Black
• Strong knowledge of networking fundamentals (TCP/IP, DNS, HTTP/S, Firewalls, VPNs, Proxy technologies)
• Experience analysing telemetry from Windows, Linux, identity, endpoint, and network sources
• Strong analytical mindset with the ability to clearly communicate findings, impact, and risk

Key Responsibilities

• Conduct proactive threat hunting activities across log, endpoint, and network telemetry to identify suspicious, stealthy, or previously unknown threats
• Develop and execute hunt hypotheses aligned to MITRE ATT&CK TTPs, adversary behaviours, and emerging threat intelligence
• Write, refine, and optimise SIEM queries using KQL, SPL, Elastic/ESQL, and Kibana Query Language
• Perform IOC analysis, enrichment, and validation, integrating internal and external threat intelligence sources
• Lead investigations from initial detection through scoping, root cause analysis, and impact assessment
• Support incident management and incident response activities, including containment, remediation, escalation, and lessons learned
• Collaborate closely with SOC teams, incident responders, red teams, and purple teams to validate detections and improve defensive coverage
• Contribute to detection logic improvements, use-case development, and continuous enhancement of hunting methodologies
• Produce clear investigation write-ups, timelines, and recommendations for technical and non-technical stakeholders
