Senior Information Assurance Consultant (SC Cleared)

We’re partnering with a growing consultancy to recruit a Senior Information Assurance (IA) Consultant to support a major client delivering critical systems within the UK’s Critical National Infrastructure (CNI).

This is a high-impact role offering real autonomy, where you’ll play a key part in shaping accreditation and assurance across complex environments. While we are ideally seeking a permanent hire, we are also open to engaging associates with the right experience.

The Opportunity

If you understand how systems truly operate — across Windows, Linux, networking, and the full OSI stack — and can translate that into clear, evidence-led assurance, this role offers the chance to make a tangible impact.

You’ll be joining a sharp, collaborative team while owning your own workstream and influencing critical security outcomes.

Key Responsibilities

  • Lead accreditation activities across multiple CNI systems
  • Specify, assess, and validate security controls across Windows and Linux environments
  • Apply broad technical understanding across the full OSI model
  • Support and contribute to risk assessments, reporting, and governance frameworks
  • Work with frameworks including NCSC CAF, GovAssure, and structured risk methodologies
  • Deliver clear, credible assurance outputs to senior stakeholders
  • Take ownership of your workstream while collaborating across wider teams

What We’re Looking For

  • Strong technical comprehension of infrastructure and systems (not hands-on, but deeply knowledgeable)
  • Experience in Information Assurance, accreditation, risk, or governance roles
  • Knowledge of NCSC CAF, GovAssure, and formal risk frameworks
  • Ability to assess and articulate security control effectiveness
  • Strong stakeholder engagement and communication skills

Desirable Qualifications

  • CISSP
  • CISM
  • TOGAF
  • SABSA
  • ISO 27001 Lead Auditor
  • Azure or AWS certifications
