Reporting into the CISO, this role provides leadership to Programme Security Leads and acts as the bridge between strategic security direction and execution.

• Ensuring consistent and effective security delivery across programmes, aligning to organisational security strategy and policies
• Acting as the primary escalation point for security delivery risks, issues, and dependencies across programmes
• Building strong relationships with programme managers, technology leaders, and business stakeholders to embed security into delivery life cycles
• Overseeing prioritisation and allocation of security resources across competing programme demands

• Tracking and reporting on security delivery metrics, risks, and maturity to senior stakeholders
• Collaborating with Security Architecture, Engineering, and GRC teams to ensure alignment and cohesion across all security disciplines
• Supporting governance processes, including risk management, exception handling, and assurance activities

We value people who take ownership, think critically, and enjoy working as part of a collaborative team tackling complex challenges.

• Proven leadership experience managing teams in a cybersecurity or technology delivery environment
• Strong stakeholder management skills, with the ability to influence at senior levels and navigate complex organisational structures
• Experience of delivering security across large-scale programmes or portfolios.
• Broad understanding of cybersecurity domains, including risk, architecture, and engineering
• Ability to balance strategic direction with pragmatic delivery and execution.
• Experience working with delivery methodologies (e.g. Agile, Dev Ops, or hybrid models) and integrating security into them.
• Strong communication skills, with the ability to translate security into business-relevant language.
• Demonstrated ability to manage competing priorities and make risk-based decisions under pressure.
