• Own the SOC operating model and its associated process– tiered analyst structure, shift roster, playbooks, runbooks and escalation matrix – and drive measurable improvement in SOC maturity using AI
• Drive detection engineering across SIEM, EDR/XDR, identity and cloud-native security tooling; develop, tune and retire use cases mapped to MITRE ATT&CK to increasedetection coverage and reduce false positives
• Ensure log source coverage across critical assets – endpoints, servers and network
• Oversee SOAR automation to accelerate alert enrichment, triage and containment actions
• Define and report SOC KPIs and KRIs (e.g. MTTD, MTTR, ATT&CK coverage, alert severity, SLA adherence) to the CISO and senior management
• Lead the organisation's response to critical zero-day and emerging vulnerabilities, including rapid exposure assessment, compensating controls and emergency patching coordination
• Establish and lead a structured, hypothesis-driven threat hunting programme based on threat intelligence, MITRE ATT&CK and anomalies observed in environment telemetry
• Develop hypotheses and techniques, and execute hunts to identify undetected threats across the environment; convert hunt findings into new or improved detections
• Gather and analyse cyber threat information and intelligence from commercial feeds, government sources (e.g. CSA / Sectoral lead) and open sources to derive insights on attack tactics, techniques and procedures (TTPs), campaigns and threat actor profiles relevant to the organisation and its sector
• Operationalise threat intelligence, including IOC ingestion and management of the threatintelligence platform (TIP)
• Act as security incident responder for cyber incidents, coordinating technical response, containment, eradication and recovery across internal teams and external partners
• Manage vendor relationships, contracts and performance for MSSP/MDR, IR retainer, maintenance for cyber security technology stack, security tooling providers; plan and manage the cyber defence budget
• Present the organisation's threat landscape, incident trends and cyber defence posture to the CISO
• Support internal and external audits and regulatory inspections, providing evidence of control design and operating effectiveness
• Proactively coordinate with technical and business stakeholders, and manage internal and external partnerships during a security incident

• A degree in Computer Science, Information Technology, Cybersecurity or a related discipline
• At least 5 years of cybersecurity experience, with substantial hands-on experience in SOC operations, incident response and digital forensics, including at least 3 years leading a team
• Proven track record of leading the response to significant incidents (e.g. ransomware, targeted intrusions, data breaches) from detection through to recovery and post-incident review
• Hands-on expertise with SIEM (e.g. Elastic, Microsoft Sentinel, Google SecOps, QRadar), EDR/XDR (e.g. CrowdStrike, Microsoft Defender, Trendmicro, Trellix), and SOAR platforms
• Experience with vulnerability management platforms (e.g. Tenable Nessus) and risk-based prioritisation approaches
• Highly analytical, with strong attention to detail and outstanding problem-solving skills; able to work independently and under pressure in a fast-paced environment
• Willingness to be on call and respond outside office hours during major incidents and/or as and when the need arises
• Relevant cybersecurity certifications
• Strong knowledge of frameworks and regulations such as MITRE ATT&CK, CIS Controls v8.1, ISO/IEC 27001:2022, Cybersecurity Act and PDPA
• Familiarity with AI-enabled security operations and threats targeting AI/LLM workloads
