Our client is looking for an experienced Systems Administrator III to support and maintain mission-critical Windows Server infrastructure across enterprise on-premises and hybrid cloud environments.

This is a hands-on, server-focused role responsible for Windows Server administration, SCCM patching, platform upgrades, high-availability clustering, production troubleshooting and infrastructure automation. The successful candidate will work closely with Infrastructure, Engineering, Security and SQL DBA teams to maintain reliable and secure production environments.

Description:

- Build, deploy, patch, upgrade and manage enterprise Windows Server environments.
- Administer Active Directory, DNS and Group Policy.
- Perform hands-on SCCM server patching and lifecycle management.
- Drive platform currency, patching and in-place server upgrades.
- Support and troubleshoot multi-node Microsoft Windows clusters.
- Support SQL Server high-availability environments and work closely with SQL DBAs.
- Resolve complex production incidents through advanced troubleshooting and root cause analysis.
- Develop PowerShell automation to improve infrastructure operations.
- Maintain runbooks, documentation and operational standards.
- Collaborate with Infrastructure, Engineering, Application, Security and DBA teams.
- Support ongoing infrastructure modernization and lifecycle initiatives.

Skills:

- 3+ years of hands-on Windows Server administration in an enterprise environment.
- Strong experience building, deploying, patching and managing Windows Servers.
- Hands-on SCCM experience specifically focused on server patching - not EUC.
- Strong Active Directory, DNS and Group Policy experience.
- Experience supporting multi-node Microsoft/Windows clustering and high-availability environments.
- Experience supporting SQL Server high availability.
- Strong PowerShell scripting and infrastructure automation experience.
- Strong production troubleshooting and root cause analysis skills.
- Ability to independently manage and resolve complex server infrastructure issues.
- Strong enterprise/server administration background.

Nice to Have:

- Azure and hybrid cloud experience
- Ansible or similar configuration management experience
- VMware virtualization experience
- Experience with PCI DSS, CIS benchmarks or payment-processing environments
- Experience working with MSSPs or managed security monitoring environments
- Relevant infrastructure or security certifications

Important:

This is a server-focused Windows administration role. Candidates should have strong enterprise Windows Server experience, including SCCM server patching and multi-node/high-availability clustering.

EUC-focused candidates and generalist IT profiles are not the target for this position.
