Job description

The IT Infrastructure Engineer designs, builds, and supports the infrastructure behind Crenlo's plants in Watertown, SD, Rochester, MN, and Greeneville, TN, and the corporate office in Bentonville, AR. The role owns systems, including VMware, Windows Server, Linux, Microsoft 365, backup, and datacenter operations. On the network side, the engineer is the next-level resource for escalation, design, engineering, and implementation, while the Network Administrator runs day-to-day operations.

Production runs on this infrastructure, so uptime, security, and fast recovery are the core of the job. The role reports to the IT Operations Manager and works closely with the helpdesk and Network Administration.

The ideal candidate is the person others call when something is truly broken, and who then makes sure it doesn't break the same way twice. They are comfortable on a manufacturing floor, can explain technical problems in plain terms, and keep good documentation.
