About the Role

The Senior Systems Administrator is a key member of the IT turnaround team, owning the infrastructure reliability of an assigned portfolio of plant sites. This high-autonomy role serves as the senior technical resource for Systems Administrators in their geographic area and contributes to enterprise-level projects and standards. The expectation is that assigned sites run well, issues get resolved before they become incidents, and the team around you gets better because you are in it. This role is well suited for an experienced infrastructure professional seeking meaningful scope, direct impact on production operations, and a clear path toward people leadership, and is not a help desk escalation role.

Responsibilities

Own the infrastructure health of assigned plant sites, including servers, virtualization, storage, endpoints, local networking, and site-level security.
Maintain accurate and current documentation of site infrastructure, including configurations, network diagrams, change history, and known issues.
Proactively monitor assigned sites using RLG tooling to identify and address degradation signals before they become incidents.
Execute infrastructure changes with disciplined change management, including planning, communication, testing, and rollback plans.
Maintain awareness of site-level security posture, executing patching schedules, EOL device retirement, and security baseline requirements.
Own L3 resolution for escalations from the outsourced L1/L2 MSP across assigned sites.
Resolve escalations, including novel issues without existing runbooks.
Identify recurring escalation patterns from the MSP and raise systemic issues to the Infrastructure Manager with recommended fixes.
Provide clear, specific technical direction to MSP remote hands during on-site work.
Serve as the informal technical lead for Systems Administrators in the geographic area.
Flag capacity problems, performance concerns, or skill gaps observed in the geographic area to the Infrastructure Manager.
Lead multi-site or cross-regional technical projects when assigned.
Contribute to and maintain RLG infrastructure standards documentation and runbooks.
Identify opportunities to improve reliability, automation, reduce manual effort, or address systemic risk.
Participate in enterprise-level infrastructure projects, integrations, and acquisitions.
Stay current with technology platforms in use across RLG and share relevant knowledge.
Build working relationships with plant managers and operations contacts in the assigned region.
Communicate clearly with non-technical stakeholders about outages, planned changes, and timelines.
Escalate to the Infrastructure Manager when a site-level issue has potential production impact.

Requirements

Bachelor's degree in computer science, information systems, or a related field, or equivalent hands-on experience.
5 or more years of IT infrastructure experience in a multi-site or enterprise environment, with demonstrated ownership of site-level infrastructure.
Experience resolving complex L3 issues independently, including issues with no existing documentation or runbook.
Experience executing infrastructure changes (migrations, upgrades, new deployments) with sound change management practice in a production environment.
Experience providing technical guidance or informal mentorship to less experienced colleagues.
Strong communication skills (verbal and written) with technical and non-technical audiences alike.
Ability to navigate in a fast-moving, acquisitive environment.
Multi-site manufacturing, industrial, or similarly operationally sensitive environment experience is a strong asset.

Skills

Windows Server and Active Directory/Entra ID administration at an enterprise level.
Virtualization: hands-on experience with VMware ESXi and/or Proxmox VE.
Networking fundamentals: VLANs, firewall rules, DNS, DHCP, and site-level connectivity.
Endpoint management in an enterprise environment.
Backup and recovery tooling; experience validating BC/DR configurations at the site level.
Security fundamentals: patching discipline, EOL device management, security baseline enforcement, and the ability to identify and escalate posture gaps.
RMM tooling for remote monitoring and management of a distributed endpoint estate.
Familiarity with ERP shop floor environments and their infrastructure requirements is an asset.
