  • Provide expert guidance on Active Directory, Windows Server, Group Policy, authentication and access control, supporting secure and well-governed identity and platform environments.
  • Assess infrastructure security risks and control effectiveness, delivering actionable recommendations and remediation plans.
  • Deliver security gap analysis and maturity assessments across identity, infrastructure and hybrid environments, identifying risks and defining prioritised, actionable remediation plans.
  • Drive consistency across customer environments by promoting standards, architectures and repeatable security practices.
  • Design and assure secure, scalable solutions aligned to customer needs, risk appetite and regulatory obligations, contributing to service innovation and translating business objectives into practical security outcomes.
  • Contribute to the evolution of the Cyber Engineering practice through service development, knowledge sharing and the creation of repeatable infrastructure security offerings.


About You

  • Experienced consultant or engineer, comfortable operating in complex environments and balancing technical requirements with operational impact, user experience and organisational constraints.
  • Able to translate security requirements into practical, scalable controls that balance confidentiality, integrity, availability and operational efficiency.
  • Strong technical credibility across identity and platform security, providing context-driven recommendations that reflect real-world implementation challenges across Microsoft environments.
  • Experience collaborating with technical and business stakeholders to ensure security solutions support organisational objectives and operational needs.
  • Clear and effective communicator who translates security risks and control gaps into actionable outcomes, with an interest in service improvement, standardisation and commercially aware delivery.


Knowledge and Experience (Highly Advantageous)

  • Proven experience with Active Directory, Entra ID, Windows Server, Group Policy and hybrid identity security.
  • Understanding of security baselines, hardening standards and control frameworks used to support risk-based recommendations.
  • Experience of phased remediation approaches across identity, infrastructure and platform security controls.
  • Working knowledge of Azure DevOps or similar delivery tooling.
