CISO Imp SME

Overview:

We are looking for an experienced Security Infrastructure Implementation Manager to join a high-stakes programme delivering secure infrastructure change into production environments. This role is hands-on and operationally critical, requiring someone who can lead implementation events under pressure, ensure compliance with security standards, and manage cross-functional teams through complex change windows.

Key Responsibilities:

• Plan, coordinate, and execute secure infrastructure implementations and technical changes into production environments.

• Own the creation, review, and execution of Implementation and Change Artefacts (runbooks, implementation plans, rollback plans).

• Lead Command and Control operations during live implementation windows — managing resources, timelines, and incident response in real time.

• Drive Change Management processes — from CAB approvals through to successful release, working closely with programme and operational stakeholders.

• Act as escalation point for any technical issues arising during implementation — with a focus on rapid triage, root cause identification, and resolution.

• Ensure security considerations and standards are embedded into all changes, with appropriate validation and documentation.

• Work collaboratively with security, infrastructure, and application teams to ensure seamless, compliant, and safe production go-lives.

• Provide out-of-hours coverage for implementation events and participate in a formal on-call rota.

• Attend and lead on-site implementation events where physical presence is required for major changes.

Skills & Experience:

• Proven experience delivering large-scale infrastructure implementations in secure environments.

• Strong understanding of information security principles and secure change governance.

• Hands-on experience with incident response and technical issue resolution in live environments.

• Comfortable operating in high-pressure go-live situations and coordinating multiple stakeholders.

• Strong knowledge of change and release management processes in enterprise IT environments.

• Experience leading infrastructure changes across a variety of platforms (e.g., Windows, Linux, networking, security appliances).

• Excellent communication and coordination skills
