We are looking for an experienced Active Directory & Azure Security Engineer on a remote working basis to support a programme of remediation and modernisation across a Microsoft environment.
The organisation has accumulated technical debt across its infrastructure and identity estate and now needs a contractor who can assess the current environment, identify areas of risk and improvement, and help implement modern best practices across Active Directory, Entra ID, Azure, Intune and Microsoft Defender.
This is a hands-on project and remediation role rather than a BAU support position. You will need to understand the potential impact of changes, plan and test effectively, and implement improvements without creating unnecessary operational risk.
Key Responsibilities
- Review the existing Active Directory environment and identify areas of technical debt, security risk and configuration improvement.
- Lead hands-on remediation and modernisation across the AD estate.
- Implement Microsoft recommended practices around identity, authentication, access control and security.
- Review and improve Group Policy, privileged access, service accounts, legacy authentication and identity configuration.
- Support alignment between on-premise Active Directory and Microsoft Entra ID.
- Review and improve Conditional Access, MFA and identity security controls where required.
- Support improvements across Azure and Intune environments.
- Work with Microsoft Defender technologies to improve endpoint and identity security.
- Assess the impact of proposed changes before implementation.
- Develop appropriate testing, rollback and mitigation plans.
- Implement changes safely across production environments.
- Identify dependencies and potential risks across legacy systems and applications.
- Produce clear technical documentation covering findings, recommendations and completed remediation.
- Work with internal infrastructure and security teams to embed improved standards and practices.
