Senior Field Service Tech

Hydro-Dyne Engineering Inc.•Clearwater, FL

3d•$32 - $34•Onsite

About The Position

Hydro-Dyne Engineering is hiring a highly skilled, controls-savvy, hands-on 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.

Requirements

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.

Nice To Haves

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.

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.
