• Define and execute a structured hypothesis-driven threat hunting programme aligned to MITRE ATT&CK TTPs relevant to client industries.


• Oversee a hunt cadence (weekly/monthly) with documented hypotheses, datasets queried, findings, and new detections produced.


• Track hunt effectiveness metrics: hunts executed, TTPs covered, detections created, threats uncovered, dwell time reduction.


• Drive proactive identification of stealthy, low-signal threats (LOLBins, identity abuse, persistence, lateral movement).


• Ensure hunt outcomes feed back into detection engineering, playbooks, and threat intel for continuous improvement.


• Govern the detection lifecycle - ideation, development, testing, deployment, tuning, retirement.


• Reviewing versioned detection library (LQL - Logpoint Query Language) mapped to MITRE ATT&CK with coverage scoring.


• Drive measurable improvement in detection coverage % per tactic/technique, per client environment.


• Drive the Reduction in false positives and alert fatigue (signal-to-noise ratio, precision/recall metrics per rule).


• Ensure detections are tested via purple team / atomic red team / BAS tools before production release.


• Review detection-as-code practices (Python)


• Oversee L1/L2 analyst quality depth of investigation, accuracy of triage, and quality of incident write-ups.

• Work with SOC OPS Manager to Maintain playbooks for top threat scenarios (ransomware, BEC, identity compromise, data exfiltration).


• Drive analyst skill uplift through case reviews, mentoring, and structured training paths.


• Operate a structured CTI capability across strategic, operational, and tactical levels.


• Track threat actor groups, campaigns, and TTPs relevant to the organisation and client base.


• Ensure CTI informs risk decisions, vulnerability prioritisation, and board reporting.


• Monitor geopolitical, regulatory, and industry events that may translate into cyber risk (POPIA, sanctions, hacktivism).


• Track exposure to active campaigns and trigger proactive defensive actions.
