Operational Technology Systems Engineer

Generac•Waukesha, WI

About The Position

The Operational Technology (OT) Systems Engineer designs, deploys, and secures connected OT systems across manufacturing facilities. The role bridges plant-floor equipment, enterprise applications, and advanced analytics platforms, delivering initiatives involving machine connectivity, industrial IoT, cloud infrastructure, CMMS integrations, and OT cybersecurity. It advances the connected factory strategy through real-time machine monitoring, predictive maintenance, secure data integration, and AI-driven operational intelligence. The engineer partners with Operations, Maintenance, Engineering, IT, Cybersecurity, Quality, and Supply Chain teams to ensure manufacturing systems are secure, connected, scalable, and aligned with business objectives. The position also supports OT-focused AWS environments and secure OT-to-cloud architectures, including cloud infrastructure, networking, monitoring, backup, and disaster recovery. It integrates manufacturing equipment and sensors with CMMS platforms, supports automated work order generation and predictive maintenance, and contributes to OT security controls, network segmentation, remote access, vulnerability management, incident response, and continuity planning. The employee is regularly required to talk, hear, use their hands to manipulate objects or controls, stand, and walk. The role may occasionally involve stooping, bending, reaching above the shoulders, and lifting up to 25 pounds. Work includes frequent and continuous computer-based tasks requiring periods of sitting, close vision, and focus adjustment. Occasional travel is required.
