Security Operations Lead

Job Description

We are seeking an experienced Security Operations Lead to build, manage, and continuously improve our internal Security Operations Centre (SOC). Based in Geneva or London, this role combines hands-on cyber defense with team leadership across three global offices (Singapore, London, and Houston). The ideal candidate is a technically proficient cybersecurity professional who can operate as both a senior incident handler (L2/L3) and a people leader shaping our detection and response capabilities.

KEY RESPONSIBILITIES

SOC Leadership & Governance

• Lead a team of 4 SOC analysts/engineers distributed across Singapore, London, and Houston, ensuring 24/7 coverage alignment and consistent service quality.
• Define and enforce SOC operating procedures, escalation paths, shift handover protocols, and performance metrics (MTTD, MTTR, false-positive rate).
• Report on SOC performance, threat landscape trends, and risk posture to the CISO and senior stakeholders.
• Manage the external SOC relationship — act as the primary interface with the outsourced SOC provider, govern service performance, drive continuous improvement, and ensure alignment with internal security objectives.

Detection Engineering & Threat Management

• Own the detection engineering lifecycle: develop, tune, and maintain analytics rules, correlation logic, and custom detections in Microsoft Sentinel (KQL) and across the broader security stack.
• Continuously improve detection coverage mapped to MITRE ATT&CK, reducing blind spots and noise.
• Evaluate and integrate threat intelligence feeds to enrich alerts and drive proactive hunting.

Incident Response & Hands-on Operations

• Act as a senior incident responder (L2/L3), leading triage, investigation, containment, eradication, and recovery for complex security incidents.
• Coordinate cross-functional incident response with IT, Legal, Compliance, and business units.
• Conduct post-incident reviews and root-cause analysis; translate findings into detection improvements and process updates.

Playbook & Process Development

• Author, maintain, and test SOC playbooks and runbooks covering the full incident lifecycle (phishing, malware, insider threat, cloud compromise, ransomware, BEC, data exfiltration, etc.).
• Improve existing playbooks and create new ones based on emerging threats, red team findings, and lessons learned.
• Drive tabletop exercises and purple-team simulations to validate playbook effectiveness.

Red Team Collaboration & Purple Teaming

• Partner with the internal Red Team to translate adversary emulation results into actionable detection rules and response procedures.
• Participate in purple-team exercises, validating detection coverage and tuning alerts based on simulated attack paths.

Training & Capability Development

• Mentor and develop SOC team members through structured training plans, knowledge-sharing sessions, and hands-on coaching.
• Foster a culture of continuous improvement and professional growth across the distributed team.
