System Administrator

About Natoli Engineering For more than 50 years, Natoli Engineering has set the standard in solid-dose tablet compression — precision punches and dies, tablet presses, data acquisition software, press refurbishing, and technical training for pharmaceutical, nutraceutical, veterinary, confectionery, and industrial manufacturers worldwide. We are a family-owned business headquartered on a 10-acre campus in St. Charles, Missouri, with technical centers across the U.S. and internationally.

Our people stay, grow, and advance here — and the technology that supports our manufacturing, engineering, and R&D operations matters to every one of them.

Position Summary The Systems Administrator is a hands-on generalist responsible for the day-to-day health of Natoli's servers, network, endpoints, and cloud services, plus direct support for employees across the office, shop floor, and remote sites. This is a broad role in a small IT team: on any given day you may be patching a server, tracing a network drop in the manufacturing area, hardening a firewall rule, onboarding a new hire, and closing help desk tickets.

You will work closely with the IT Manager on infrastructure projects while owning the operational routines that keep the business running.

This role is ideal for someone with a few years of solid infrastructure experience who wants breadth — systems, networking, and security — rather than a single narrow specialty.

Key Responsibilities Systems Administration Administer Windows Server environments, Active Directory, Group Policy, DNS, DHCP, and file/print services.

Administer Microsoft 365 / Entra  and license provisioning, Exchange Online, SharePoint, One Drive, and Teams.

Maintain virtualization hosts and guests (Scale and/or Hyper-V), including resource monitoring, capacity planning input, and VM lifecycle.

Own backup and recovery operations: verify job completion, perform restore testing, and support disaster recovery and business continuity planning.

Manage patching and update cycles for servers, workstations, and applications; schedule and execute maintenance windows with minimal production impact.

Provide infrastructure support for line-of-business systems, including ERP/MRP, engineering and CAD/CAM applications, and shop-floor and quality systems (coordinating with vendors and application owners as needed).Monitor system health, respond to alerts, and investigate performance issues before they become outages.

Networking Support and maintain LAN/WLAN and WAN infrastructure: switches, routers, firewalls, VPN, wireless access points, and structured cabling across office, manufacturing, and warehouse areas.

Configure VLANs, DHCP scopes, port assignments, and QoS; troubleshoot connectivity issues end to end, from the wall jack to the cloud.

Support site-to-site and remote-user VPN connectivity for satellite technical centers and traveling staff.

Maintain accurate network documentation, IP schemes, and rack/cabling diagrams.

Coordinate with ISPs, telecom, and low-voltage vendors on circuits, installs, and outages.

Security Administer endpoint protection/EDR, email security and filtering, and multi-factor authentication.

Apply least-privilege principles to accounts, shares, and administrative access; conduct periodic access reviews.

Support vulnerability management: run and interpret scans, prioritize remediation, and verify fixes.

Assist with security awareness training, phishing simulations, and incident response — containment, investigation support, and documentation.

Help maintain IT policies, standards, and evidence for customer, quality, or cyber-insurance audits.
