The Field I&E Specialist serves as the organization's primary subject matter expert for advanced instrumentation, electrical, and controls troubleshooting across a network of water and wastewater treatment facilities. This is a highly autonomous, travel-intensive role (75%+ travel) requiring the individual to deploy to sites when issues exceed the diagnostic capabilities of local operators or maintenance staff.

The ideal candidate brings deep, hands‑on expertise across PLC/SCADA systems, electrical distribution, motor controls, and process instrumentation and is equally comfortable troubleshooting a field instrument loop or navigating a PLC ladder logic fault. Strong communication skills are essential, as this role regularly interfaces with site operators, plant managers, and engineering staff to resolve critical issues and transfer knowledge.

• Respond to escalated instrumentation, electrical, and control system failures at water and wastewater treatment sites that are beyond the scope of local operator capabilities.
• Diagnose and resolve complex faults across PLC platforms (Allen‑Bradley/Rockwell preferred), SCADA systems, HMI interfaces, and field control networks (Ethernet/IP, Modbus).
• Troubleshoot low and medium voltage electrical systems including MCCs, VFDs, soft starters, switch gear, transformers, and distribution panels.
• Diagnose and repair field instrumentation including flow meters, level transmitters, pressure transducers, pH/ORP/DO/turbidity analyzers, and online process analyzers.
• Perform in‑depth loop checks, signal tracing, and fault isolation across 4‑20mA, HART, and digital I/O circuits.
• Assess site conditions, develop rapid troubleshooting plans, and execute repairs with minimal disruption to plant operations.

• Perform testing, diagnostic, and repair work on motors, motor control circuits, VFDs, relay logic, and programmable relays.
• Conduct infrared thermography, insulation resistance testing (megger), and power quality analysis as needed.
• Read, interpret, and redline electrical schematics, one‑line diagrams, and as‑built drawings; update site documentation following repairs.
• Ensure all electrical work is performed in strict compliance with NFPA 70E arc flash safety standards and site‑specific LOTO procedures.

• Perform precision calibration, loop tuning, and verification of process instruments using appropriate reference standards and calibration equipment.
• Conduct as‑found / as‑left documentation and maintain calibration records in accordance with regulatory and quality requirements.
• Advise site staff on instrument selection, installation best practices, and preventive maintenance intervals.

• Collaborate directly with local operators and site maintenance staff to resolve issues, explain findings, and build on‑site diagnostic capabilities.
• Provide on‑the‑job coaching and informal training to site personnel during visits to reduce recurrence of similar issues.
• Prepare clear, concise field service reports documenting findings, work performed, parts used, and recommended follow‑up actions.
• Identify recurring or systemic equipment/system issues across the portfolio and escalate to management with recommendations.
• Assist with capital project planning by providing field assessments and technical input on aging or failing systems.

Any other duties or projects as assigned by management.

• Associate’s degree in an electronic related field or equivalent experience.
