Currently looking for an Infrastructure/Security Engineer for a 6-month contract to address a backlog of critical security audit findings.
In this hands-on operational role, you will take ownership of security remediation items from initial investigation through implementation, testing, change management, and final audit closure.

- Audit & Compliance Documentation: Record initial findings, remediation actions, test results, evidence artifacts, and any residual risks.
- Reporting & Tracking: Provide structured weekly progress reports covering key milestones, blockers, dependencies, risks, and estimated completion dates.





To be successful in this position you must be an experienced Infrastructure/Security Engineer who has hands-on experience in IT infrastructure operations, with demonstrable experience executing security remediation initiatives.

Technical Stack Expertise

- Cloud & Identity: Microsoft Azure, Microsoft Entra ID, Azure Storage, Azure Policy, Conditional Access, and enterprise applications.
- Endpoint & Systems Management: Microsoft Defender for Endpoint, Defender Antivirus, Microsoft Intune, and Group Policy (GPO).
- Core Infrastructure & Automation: Windows Server, Active Directory Domain Services (AD DS), DNS, Kerberos, SMB, NTLM, and PowerShell scripting.
- Security & Operations: Mimecast, vulnerability scanners, security incident management, and audit evidence management.

Security & Delivery Capabilities

- Expertise in vulnerability and patch management, identity hardening, cloud security posture, and security control implementation.
