About The Position

The IT Infrastructure Engineer designs, builds, and supports infrastructure for Crenlo’s plants in Watertown, South Dakota; Rochester, Minnesota; and Greeneville, Tennessee, as well as its corporate office in Bentonville, Arkansas. The role owns systems including VMware, Windows Server, Linux, Microsoft 365, backup, and datacenter operations. It also serves as the next-level resource for network escalation, design, engineering, and implementation, while the Network Administrator handles day-to-day network operations. Because production depends on this infrastructure, uptime, security, and fast recovery are central priorities. Reporting to the IT Operations Manager, the engineer works closely with the helpdesk and Network Administration. The role is suited to someone who can resolve complex issues, address root causes to prevent recurrence, communicate technical problems clearly, maintain thorough documentation, and work comfortably in manufacturing environments.
