Hydro-Dyne Engineering is hiring a highly skilled, controls-savvy, hands-on Wastewater Field Service Technician to support municipal wastewater screening and solids handling equipment in the field. This role is for a technician who can troubleshoot industrial controls (PLC/VFD/sensors/networks) and also work confidently on the physical equipment (screens, compactors, drives, chains, sprockets, reducers, bearings, alignment, washwater systems, and related components).
This is not a parts-swap role. You will be expected to diagnose problems accurately, make safe and durable repairs, verify performance in AUTO under real process conditions, and document work in a professional, customer-ready manner.
-
Troubleshoot and commission PLC-controlled wastewater equipment, including VFDs, motor starters, smart relays, MCC interfaces, and control panels.
-
Diagnose instrumentation and field devices: level (ultrasonic/radar), pressure, flow, proximity/limit switches, current monitors, and safety interlocks.
-
Validate control sequences and permissives; confirm timers/alarms/setpoints; verify I/O and correct wiring faults.
-
Troubleshoot industrial communications as applicable (EtherNet/IP, Modbus, Ethernet, serial, remote I/O, etc.).
-
Interpret electrical drawings/schematics and use test equipment to isolate faults safely.
-
Diagnose and repair mechanical issues on screens, compactors, conveyors, and related solids handling equipment.
-
Perform hands-on service including reducers, motors, couplings, sprockets, chains, bearings, seals, brush assemblies, and wear components.
-
Clear jams/plugs safely and identify the underlying cause (process conditions, maintenance practices, setup, or component failure).
-
Use appropriate rigging practices to remove/install heavy components as required.
-
Verify alignment, binding points, washwater performance, leakage sources, and overall equipment condition.
-
Confirm equipment operates properly under real process conditions (AUTO mode, normal/storm flows, debris load).
-
Communicate clearly with operators, maintenance teams, electricians, and plant leadership; set expectations and provide timely updates.
-
Produce strong field documentation: photos, findings, root cause, corrective actions, parts needed, and next steps.
-
Identify recurring failure patterns and route feedback internally to support continuous improvement.
-
Independently run field troubleshooting calls with minimal escalation.
-
Reduce return trips through correct diagnosis, verification testing, and clear parts/scoping.
-
Deliver customer-ready closeout reports with facts, photos, and actionable next steps.
-
Become a go-to resource for controls triage while remaining highly capable on the mechanical side.
-
5+ years hands-on field experience combining industrial electrical/controls troubleshooting and mechanical service work.
-
Strong understanding of PLC/controls fundamentals (I/O, permissives/interlocks, sequencing) and the ability to troubleshoot logically.
-
Strong understanding of VFD troubleshooting (fault history, parameters, motor protection, and communications considerations).
-
Working knowledge of 24VDC/120VAC/480VAC systems in MCC environments and safe troubleshooting practices.
-
Instrumentation troubleshooting experience (4-20 mA, discrete signals, basic calibration/verification).
-
Ability to read and work from electrical schematics and mechanical prints.
-
Comfort with test equipment (multimeter, clamp meter; megger/loop calibrator a plus).
-
Valid driver's license with clean driving record; ability to travel extensively nationwide.
-
OSHA 10 and Confined Space required; must pass background and drug test.
-
Municipal wastewater plant experience (screens, compactors, conveyors, grit systems, pumping stations).
-
Experience with common PLC/HMI ecosystems (Allen-Bradley, Siemens, Schneider) and/or smart relays.
-
Experience with level instrumentation commonly used in wastewater applications (including Hydroranger and similar platforms).
-
Commissioning/startup experience (loop checks, I/O checkout, SAT support).
-
Understanding of VFD grounding/noise best practices in harsh industrial environments.
-
Work in industrial wastewater environments: stairs/ladders, tight spaces, outdoor work in heat/cold, wet conditions.
-
Lift and carry up to 50 lbs; use hand and power tools; perform hands-on mechanical service work.
-
Follow all safety requirements and site-specific PPE rules.
