Adeptis Group is recruiting on behalf of a leading Critical National Infrastructure organisation undergoing a major cybersecurity transformation. This is a high-impact role at the heart of a global enterprise that provides essential services to millions of people every year.

We're seeking a hands-on and strategic Cyber Incident Response Team (CIRT) Manager to design, implement, and mature a group-wide cyber incident response function. This is a rare greenfield opportunity to build and shape the incident response operating model from scratch—working alongside a newly onboarded MSSP while setting the foundations for a future internal capability.

• Defining the tooling roadmap for incident response and forensic capabilities
• Acting as the primary liaison with the MSSP to align SLAs, KPIs, and operational playbooks
• Leading incident coordination across internal and external teams
• Building relationships with stakeholders across business units to ensure risk-aligned response
• Developing a strategic business case to scale and insource CIRT capabilities
• Driving continuous improvement through post-incident reviews and threat landscape analysis
• Ensuring compliance with regulatory requirements and frameworks (e.g. GDPR, NIST, PCI-DSS, MITRE ATT&CK)

Requirements

• 5–10 years of experience in Security Operations, CIRT, or senior SOC roles
• Strong leadership capability or experience managing incident response teams
• Deep technical knowledge of SIEM, SOAR, EDR, and forensic tooling
• Strong grasp of threat detection methodologies and security frameworks
• Proven ability to engage senior stakeholders and drive alignment across functions
• Recognised certifications (e.g., CISSP, CISM) preferred
• Background in regulated or CNI environments is advantageous
