Job description

Working for a renowned telecoms organisation.

Your new role

Working for a renowned telecoms organisation within The Emergency Services Network (ESN) team in a critical national infrastructure program and a strategic priority for the company, ensuring secure and reliable communications for Emergency Services where availability can be a matter of life or death. Security is fundamental to the ESN, requiring robust governance and assurance to maintain the confidentiality, integrity, and resilience of the network against a wide range of cyber and physical threats.

As an ESN Cyber Security Governance & Assurance SME, you will help lead the delivery of security governance, compliance, and risk management across the ESN programme. This includes implementing ISO27001-compliant security strategies, managing contractual security obligations, and ensuring adherence to frameworks such as the HMG Security Policy Framework. You will work closely with internal teams, suppliers, and customer security stakeholders to provide assurance, drive continuous improvement, and maintain confidence in the ESN's security posture.

What you'll need to succeed

• Strong experience in security governance and assurance, with a proven track record in delivering security accreditations and managing security processes.
• Ability to develop and write security procedures, controls documentation, and assurance artefacts (e.g., RMADS, Security Operating Procedures).
• Demonstrated expertise in security auditing and compliance activities, including producing reports and actionable recommendations.
• Hands‑on experience administering security processes and performing assurance activities, ideally within Central Government departments or agencies.
• In‑depth knowledge and practical experience with ISO27001 controls, audits, and implementation.
• Experience working in public sector environments or telecommunications projects is highly desirable.
• Experience working with HMG security controls.
• A proactive, delivery‑focused approach—this role requires someone who can "roll up their sleeves" and produce high‑quality documentation, not just manage teams.
• Must hold SC Clearance and BPSS as a minimum requirement.

What you'll get in return

Flexible working options available.
