Job Title – Oilfield Electrical & Data Communications Technician

Location - Houston, TX (with travel to supplier and field locations; up to 70% travel)

Reports To – Operations manager, Houston

Position Summary

We are seeking an experienced Electrical & Data Communications Technician to support electrical (480V–110V), instrumentation, automation, and communications systems on our mobile hydration units during oilfield operations. This role installs, troubleshoots, maintains, and commissions field equipment, ensuring reliable data transmission between field devices, control systems, and remote monitoring platforms across protocols including Modbus TCP, RS-232, and RS-485.

The ideal candidate combines strong electrical and instrumentation knowledge with industrial networking and telemetry experience, works independently in demanding field environments, and responds effectively to equipment and communications issues. Oilfield experience is a plus but not essential.

Key Responsibilities

Install, maintain, and troubleshoot electrical/electronic equipment, instrumentation, sensors, transmitters, control panels, PLCs, and field devices.
Configure and troubleshoot industrial networks and communication protocols (Modbus RTU/TCP, Ethernet/IP, TCP/IP, RS-232/RS-485), including switches, routers, modems, and wireless access points.
Diagnose connectivity, signal, addressing, and configuration issues; support automation/communications equipment commissioning.
Perform electrical testing, calibration, and preventive maintenance; read schematics, wiring diagrams, and loop diagrams.
Verify accurate transmission of pressure, flow, temperature, tank level, production, and alarm data.
Collaborate with operations, automation, engineering, and IT teams; document equipment changes, network configurations, and maintenance records.
Follow company safety policies and applicable electrical/oilfield regulations; participate in on-call/emergency response as needed.

Qualifications

2+ years of experience in electrical, E-Tech, instrumentation, automation, telemetry, or industrial communications (oilfield experience a plus).
Strong electrical troubleshooting skills and working knowledge of industrial networking/data communications.
Experience with PLCs, instrumentation, or automation equipment; ability to read schematics and technical documentation.
Basic IP networking knowledge (addressing, switches, routers, Ethernet).
Proficiency with electrical test equipment (multimeters, clamp meters).
Valid driver's license; ability to travel and work in remote outdoor oilfield environments.

Preferred Qualifications

Experience with oilfield production, drilling, completions, artificial lift, or pipeline operations.
PLC/HMI experience; router and network switch configuration.
Familiarity with Modbus, Ethernet/IP, or similar protocols.
Knowledge of VFDs, motor controls, MCCs, and electrical distribution.
Instrumentation calibration experience; relevant electrical, instrumentation, automation, or networking certifications.

Key Competencies

Works independently in remote field environments with minimal supervision; sound judgment under time pressure.
Methodical troubleshooter who isolates electrical, instrumentation, and network faults to root cause rather than symptom.
Safety-first mindset around energized, rotating, and pressurized systems; challenges unsafe conditions.
Clear communicator across operations, automation, engineering, and IT; documents work accurately and promptly.
Rapid learning agility on new equipment, protocols, and control platforms.
Strong ownership of outcomes and resilience across extended shifts, on-call, and callout work.

Physical & Field Requirements

Ability to work outdoors in remote locations and varying weather; climb stairs, ladders, and equipment structures; lift and carry tools/equipment; work around rotating, electrical, and pressurized systems. Willingness to work overtime, weekends, holidays, or on-call shifts as required.
