• Build and support highly available virtual infrastructure using VMware and Cisco UCS to ensure performance, reliability, and scalability of MES platforms.
• Administer core Windows Server services, including Active Directory, Group Policy, DNS, and DHCP, to maintain a secure and compliant manufacturing IT environment.
• Manage Citrix environments to deliver MES applications securely and efficiently to both plant-floor users and remote teams.
• Provide advanced infrastructure support for MES systems, resolving complex issues in collaboration with internal teams and external vendors.
• Ensure all system changes follow regulatory and compliance requirements, while maintaining thorough documentation such as disaster recovery plans, backup configurations, and standard operating procedures.

Skills:

• 5+ years of experience in systems administration within a production/manufacturing environment.
• Prior experience supporting an MES (e.g., Siemens, Rockwell) is highly desirable.
• Advanced experience with enterprise backup platforms such as Veeam and Dell EMC Avamar, along with managing storage targets including SAN, NAS, and cloud-based systems across vendors like Tintri and HPE.
• In-depth expertise in VMware technologies (vSphere, ESXi, vCenter) and hands-on management of Cisco UCS infrastructure.
• Extensive knowledge of Windows Server environments, including Active Directory, Group Policy, DNS, and DHCP administration.
• Strong proficiency in Citrix Virtual Apps and Desktops and application virtualization to support secure and scalable access.
• Solid understanding of Cisco networking, including Layer 2/3 configurations, VLANs, wireless access points, and basic voice gateway troubleshooting.
• Highly analytical with strong problem-solving ability, clear and effective communicator, detail-oriented, proactive in ensuring system stability and data protection, and capable of leading projects and mentoring junior team members.

Education:

• Bachelor's degree required. 5+ years of experience in systems administration within a production/manufacturing environment. Prior experience supporting an MES (e.g., Siemens, Rockwell) is highly desirable.
