RLG is a PE-backed manufacturer operating 28 plant sites across the United States and Canada. Following a period of rapid, acquisition-driven growth, the company is executing a focused IT turnaround: standardizing infrastructure across a fragmented estate, maturing its cybersecurity posture, and building the team and operating model to support continued M&A.;

The Senior Systems

Administrator is a key member of that team. This role owns the infrastructure reliability of an assigned portfolio of plant sites, serves as the senior technical resource for Systems Administrators in their geographic area, and contributes to enterprise-level projects and standards that affect the full RLG estate. It is a high-autonomy role with real ownership: 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.

It is not a help desk escalation role. L1 and L2 support is handled by an outsourced MSP; the Senior Systems Administrator owns everything above that threshold.

Site Infrastructure Reliability

Own the infrastructure health of your assigned plant sites: servers, virtualization (Proxmox/VMware/Nutanix), storage, endpoints, local networking, and site-level security posture. Maintain accurate, current documentation of site infrastructure including configurations, network diagrams, change history, and known issues. every site you own should be understandable to someone who has never visited it. Monitor assigned sites proactively using RLG tooling; Execute infrastructure changes with disciplined change management: planned, communicated to affected stakeholders, tested where possible, and with a rollback plan in place before you start.





Maintain awareness of site-level security posture; execute patching schedules, EOL device retirement, and security baseline requirements on time. Own L3 resolution for escalations from the outsourced L1/L2 MSP across your assigned sites. You are the top of the internal escalation stack for those sites.

Provide clear, specific technical direction to MSP remote hands during on-site work at your sites.

Regional Technical Leadership

Serve as the informal technical lead for Systems Administrators in your geographic area. Flag capacity problems, performance concerns, or skill gaps you observe in your geographic area to the Infrastructure Manager. Lead multi-site or cross-regional technical projects when assigned by the Infrastructure Manager.

You are a net contributor to the team knowledge base. Identify opportunities to improve reliability, automation, reduce manual effort, or address systemic risk across your sites or the broader estate. Participate in enterprise-level infrastructure projects, integrations, and acquisitions.

Understand what they do, what their IT dependencies are, and what a bad day looks like for them. 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, before that impact occurs if at all possible.





Bachelor's degree in computer science, information systems, or a related field, or equivalent hands-on experience.

Microsoft

Certified (Azure Administrator, M365 Administrator, or equivalent), VMware VCP, or comparable infrastructure credentials. CompTIA (Server+, Network+, Security+) valued for candidates building toward those levels. 5 or more years of IT infrastructure experience in a multi-site or enterprise environment, with demonstrated ownership of site-level infrastructure rather than support queue participation. ~ 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. ~ Multi-site manufacturing, industrial, or similarly operationally sensitive environment experience is a solid asset.

Technical Skills Windows

Server and Active Directory/Entra ID administration at an enterprise level.

Experience migrating between hypervisor platforms is an asset.

Networking fundamentals: VLANs, firewall rules, DNS, DHCP, and site-level connectivity. You do not need to be a network engineer, but you need to be able to own first-line network issues at sites without escalating.

experience validating BC/DR configurations at the site level. RMM tooling for remote monitoring and management of a distributed endpoint estate. Familiarity with ERP shop floor environments and the infrastructure requirements that support them is an asset (e.g.,
