We're seeking a skilled Information Assurance Consultant to join a key government agency, supporting the Information, Policy and Security (IPS) Cyber and Information Assurance (C&IA) function.
You'll provide expert direction and assurance across multiple programmes and projects, ensuring that the technical, procedural, and physical controls in place to protect sensitive data are robust, proportionate, and aligned with government standards.

This is a hands-on, advisory role-ideal for someone who thrives on influencing at programme level while also getting into the detail of how assurance frameworks are applied across IT, data analytics, and wider business functions.

Key Responsibilities

Provide cyber and information assurance advice to new and ongoing projects, shaping security requirements and framework controls.

Conduct security audits, risk assessments, and assurance reviews to ensure compliance with HMG Security Classifications and relevant regulations and standards.

Advise on IT security solutions and emerging technologies, maintaining up-to-date knowledge of best practice.

Collaborate with other security disciplines - including Cyber Operations, Physical Security, and Personnel Security - to manage and reduce data loss risks.

Deliver formal technical assurance on system and architectural designs, ensuring appropriate security of information and processing facilities.

Support incident management activities, offering expert input and response guidance.

Required

You'll bring both technical depth and strategic assurance expertise, ideally gained within a secure or government environment.
You're confident engaging with multiple stakeholders, managing risk in complex programmes, and balancing security controls with operational need.

Essential:

Degree or equivalent in an IT-related discipline or recognised security certifications (e.g. GIAC, ISC2, BCS, ISACA).

Demonstrable experience in information assurance, IT risk management, or cyber security within government or critical national infrastructure.

Strong understanding of government security frameworks and assurance processes.

Active SC clearance (enhanced SC preferred).
