• Provide operational support for Rockwell/Allen‑Bradley systems (majority of site equipment) and support Ignition SCADA and Beckhoff PLC equipment as applicable.
• Work in hazardous/classified areas where ignition source control requirements apply, following site isolation practices and procedures.
