Senior Wastewater Field Tech

Open 45d

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 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.

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.
