  • Provide operational support for Rockwell/Allen-Bradley systems (majority of site equipment) and support Ignition SCADA and Beckhoff PLC equipment as applicable.
  • Work in hazardoclassified areas where ignition source control requirements apply, following site isolation practices and procedures.
  • Provide clear handoffs and "weekend learnings" to weekday engineering/maintenance teams.
