Description
Talenza have partnered with a large complex critical infrastructure organisation on the search for a security leader to join a large, complex organisation operating at the intersection of cloud, software engineering, and operational technology environments.
Reporting to the executive leadership team, this role will lead the next phase of the organisation's cyber security maturity journey, evolving the security function from foundational capability to a more targeted, risk-driven approach.
This is a highly visible leadership role requiring an individual who can operate strategically while remaining close to execution and delivery.
About the Role
The organisation has already delivered the majority of its existing cyber security roadmap. The next phase is focused on prioritisation, business enablement, and ensuring security investment is directed towards initiatives that materially reduce risk.
Key responsibilities include:
Develop and deliver the long-term cyber security strategy and roadmap.
Strengthen secure software engineering practices across in-house development teams.

Mature vulnerability management, identity security, and incident readiness capabilities.
Drive improvements in data protection, classification, and governance.
Maintain compliance with regulatory and critical infrastructure obligations.
Lead strategic vendor and consultancy engagements.
Mentor and develop the existing cyber security team.
Influence stakeholders across engineering, operations, and executive leadership.
About You
You are a technically credible security leader who is comfortable moving between executive conversations and technical discussions.
You bring experience across:
Cloud security (AWS and/or Microsoft environments)
Secure software development and DevSecOps
Operational technology or critical infrastructure security
Security operations and incident response
Regulatory and governance frameworks
Leading teams and influencing without authority
Most importantly, you take a pragmatic approach to cyber security and focus on implementing controls that genuinely reduce risk and support business outcomes.
Why This Role?
This opportunity offers the chance to:
Shape a long-term cyber strategy through to 2032.
Influence security across cloud, software, and OT environments.
Work within a collaborative, low-ego leadership culture.
Join an organisation investing heavily in technology, AI, and security capability.
Play a visible role in business growth and resilience.
