Position Summary:

The Control Systems Technician provides advanced electrical, instrumentation, and controls support across multiple Renewable Natural Gas (RNG) facilities. This role serves as the company’s senior field electrical and I&E resource for critical plant systems, including low-voltage controls, 480V power systems, motor control centers, VFDs, instrumentation loops, analyzers, control panels, PLC input/output circuits, SCADA/HMI field support, and electrical distribution systems up to 4160V. The position supports safe, reliable, compliant, and efficient plant operations through troubleshooting, repair, preventive maintenance, calibration support, commissioning support, outage support, and reliability improvement work.

The successful candidate must be a hands-on industrial electrician with the ability to troubleshoot from field devices and low-voltage control circuits through motor controls, instrumentation, PLC I/O, and plant electrical distribution systems. This position requires strong field judgment, safe work habits, clear documentation, and the ability to work

independently across multiple operating sites.

Key Responsibilities:

• Troubleshoot electrical, instrumentation, and control systems from field devices through low-voltage control systems, including 24 VDC, 120 VAC, relay logic, control power, HMI/SCADA, solenoids, and switches.
• Troubleshoot and repair industrial electrical power systems, including 480V systems and electrical distribution systems up to 4160V including MCCs, motors, VFDs, and breakers.
• Supporting instrumentation used in biogas/RNG and digester operations including pressure transmitters, temperature transmitters, RTDs, thermocouples, flow meters, level instruments, valve positioners, pressure switches, differential pressure devices, gas detection devices, and analytical instruments.
• Diagnose control issues including permissives, interlocks, shutdown circuits, and PLC-related faults.
• Perform loop checks, signal verification, and field validation of control systems.
• Support maintenance and repair of electrically driven rotating equipment, including motors, compressors, blowers, pumps, chillers, fans, skids, and auxiliary systems.
• Use drawings (one-lines, schematics, P&IDs, loop diagrams) to troubleshoot and verify system operation.
• Use a Megger to perform motor insulation resistance testing and assess motor condition based on test results.
• Support commissioning, startups, outages, and major maintenance events (TARs)
• Coordinate contractors for electrical testing, switching, and major repairs.
• Execute and improve preventive maintenance and inspection programs.
• Review one-line diagrams, electrical distribution drawings, coordination studies, equipment documentation, and vendor manuals to support troubleshooting, equipment changes and maintenance planning.
• Assist in developing and improving calibration procedures, instrument PMs, inspection checklists, and spare-parts recommendations.
• Prepare electrical/I&E work scopes, parts lists, tools, isolation requirements, testing requirements, and contractor support needs for planned work.
• Identify and resolve recurring failures to improve reliability and uptime.
• Maintain documentation, redline, and work records with clear troubleshooting detail.
• Ensure all work is performed safely in compliance with applicable electrical codes, company standards, and site requirements.

Qualifications:

• Active Master Electrician license or equivalent senior industrial electrical qualification required.
• 10 + years of industrial electrical experience in processing plants. Hands-on experience with: - 24VDC / 120VAC controls - 480V motor control and MCCs - Electrical distribution up to 4160V
• Ability to troubleshoot instrumentation and control systems.
• Working knowledge of PLC/HMI systems.
• Ability to read electrical drawings, P&IDs, and schematics.
• Strong electrical safety knowledge (LOTO, arc flash, energized work)
• Ability to document work accurately, including symptoms, observations, readings, troubleshooting steps, corrective actions, parts used, labor time, and final equipment condition.
• Ability to travel frequently supports multiple sites, planned outages, and urgent troubleshooting.

Preferred Skills:

• Experience in RNG, biogas, oil & gas, or similar industries
• Experience working as an I&E Technician, E&I Technician, Instrument Technician, Controls Technician, Industrial Electrician, or Senior Electrician in a process plant environment.
