Industrial Automation Controls Specialist — Rohnert Park, CA

You arrive just before 8:00 a.m. to walk the production floor. Overnight, one filler lane logged intermittent sensor faults. You trace the issue to a drifting proximity sensor, verify signals through the HMI, and make a minor logic tweak to the PLC to stabilize the line. By mid-morning, you’re calibrating a pressure transmitter for a CIP loop and updating the wiring diagram to reflect a recent VFD swap. After lunch, you partner with Maintenance and Operations to schedule predictive checks on a critical conveyor and assist with a small controls upgrade coming next week. Before you head out around 5:00 p.m., you document the day’s changes and confirm you’re available for on-call coverage if needed.
