Field Instrument and Electrical Specialist

CAMBRIAN INNOVATION, LLC•Houston, TX

3d•Remote

About The Position

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.

Requirements

Associate’s degree in an electronic related field or equivalent experience.
Substantial experience in a process control environment, typically five or more years with demonstrated competency.
Valid driver’s license.
Expert-level reading and interpretation of electrical schematics, P&IDs, instrument loop drawings, and control panel layouts.
Proficiency with calibration and test equipment: loop calibrators, multimeters, meggers, oscilloscopes, and power analyzers.
Strong working knowledge of NEC, NFPA 70E, and OSHA electrical safety and LOTO requirements.
Familiarity with water/wastewater treatment processes, equipment, and instrumentation applications preferred.
Excellent problem-solving skills with the ability to work independently in unfamiliar facility environments.
Clear written and verbal communication skills; ability to explain technical issues to non-technical operators and managers.
Self-directed and highly organized; able to manage travel logistics, prioritize multiple site requests, and work with minimal supervision.
Stand, walk, climb, bend, and work in confined, elevated, or restricted-access areas for extended periods.
Lift and carry up to 50 lbs. of tools, equipment, and parts unassisted.
Work in confined spaces (confined space entry training and medical clearance required).
Exposure to outdoor weather extremes, chemicals, noise, heat, and biological hazards typical of water/wastewater environments.
Required to wear and properly use PPE including arc flash PPE, respirators, chemical-resistant clothing, and fall protection as conditions dictate.
Must be available to respond to critical site emergencies outside normal business hours as needed.

Nice To Haves

Familiarity with water/wastewater treatment processes, equipment, and instrumentation applications.

Responsibilities

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, switchgear, 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.
