Senior Wastewater Field Tech

Role Summary 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.

Key Responsibilities Controls / Electrical / Automation 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 per missives; confirm timers/alarms/setpoints; verify I/O and correct wiring faults.

Troubleshoot industrial communications as applicable (Ether Net/IP, Modbus, Ethernet, serial, remote I/O, etc.).Interpret electrical drawings/schematics and use test equipment to isolate faults safely.

Mechanical / Equipment Service 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).Customer Communication and Documentation 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.

What Success Looks Like (First 90 Days)
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.

Required Qualifications 5+ years hands-on field experience combining industrial electrical/controls troubleshooting and mechanical service work.

Strong understanding of PLC/controls fundamentals (I/O, per missives/interlocks, sequencing) and the ability to troubleshoot logically.

Strong understanding of VFD troubleshooting (fault history, parameters, motor protection, and communications considerations).Working knowledge of 24

VDC/120

VAC/480

VAC 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.

Preferred Qualifications 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 Hydro ranger and similar platforms).Commissioning/startup experience (loop checks, I/O checkout, SAT support).Understanding of VFD grounding/noise best practices in harsh industrial environments.

Physical and Field Requirements 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.
