We are looking for a Sr. Systems Engineer to support and enhance enterprise infrastructure. This long-term contract position is suited for a hands-on, detail-oriented individual who can manage core Microsoft platforms, strengthen endpoint and identity services, and help maintain a secure, reliable IT environment. The role will work across server administration, cloud-connected services, endpoint operations, and security response while partnering with technical teams and business stakeholders to improve operational performance.

Responsibilities:

• Oversee daily administration of Windows Server environments and maintain stable performance across core infrastructure systems.

• Support Hyper-V ecosystems by managing clustered hosts, virtual machines, storage resources, backup operations, and disaster recovery readiness.

• Maintain enterprise endpoint management through Microsoft Intune and related tools, including application rollout, policy configuration, compliance enforcement, and remediation scripting.

• Administer identity platforms such as Active Directory, Microsoft Entra ID, and Microsoft 365, including access controls, authentication methods, and user lifecycle activities.

• Investigate infrastructure and security incidents, resolve vulnerabilities, and contribute to response efforts and root cause reviews.

• Provide advanced troubleshooting as an escalation point for complex systems, endpoint, and networking issues affecting users and business services.

• Build and refine automation using PowerShell to reduce manual effort, improve consistency, and support scalable IT operations.

• Create and update technical documentation, operational standards, and support procedures to strengthen service delivery and governance.

• Work with vendors, managed security partners, and internal teams to coordinate platform support, compliance activities, and infrastructure improvements.

• At least 4 years of experience in enterprise infrastructure or systems engineering roles.
• Strong hands-on knowledge of Microsoft 365, Active Directory, Microsoft Entra ID, Windows Server, Hyper-V, Intune, and PowerShell scripting.
• Solid understanding of enterprise networking concepts, including firewalls, switching, wireless connectivity, VPN technologies, and secure access methods.
• Experience with endpoint management, patching, compliance enforcement, and troubleshooting across Windows, macOS, and mobile devices.
• Background in security operations, including vulnerability remediation, endpoint protection, multifactor authentication, single sign-on, and privileged access practices.
• Ability to work independently on complex infrastructure initiatives with strong analytical and problem-solving skills.
• Experience supporting regulated environments and compliance-driven processes such as access reviews, audit support, or SOX-related controls.
• Preferred exposure to tools and platforms such as ServiceNow, CrowdStrike, Arctic Wolf, Mimecast, Veeam, Nasuni, SharePoint, Citrix technologies, Palo Alto, or Meraki.
