Field Service Technician

About This Role

The Field Service Technician installs, commissions, maintains, and troubleshoots ozone generation and ultraviolet (UV) disinfection systems for water and wastewater treatment. This role ensures optimal system performance, regulatory compliance, and reliable disinfection processes, working independently at customer sites while supporting advanced oxidation processes and integrated treatment systems.

Responsibilities

• Install, commission, and service ozone generation systems (corona discharge units, oxygen concentrators, ozone destruct units) and UV disinfection systems (low- and medium-pressure UV reactors)
• Perform preventive and corrective maintenance on system components including power supplies, ballasts, UV lamps, quartz sleeves, ozone generators, compressors, and associated piping/valves
• Troubleshoot electrical, mechanical, and control issues, including PLC-based systems and remote monitoring platforms
• Monitor and optimize disinfection performance (UV dose, UV transmittance, ozone concentration, CT values)
• Clean and maintain UV reactor components (e.g., sleeve cleaning systems) and ozone system components (e.g., dielectric tubes, diffusers)
• Read and interpret P&IDs, electrical schematics, and control logic diagrams
• Support system startups, validation, and performance testing
• Maintain detailed service reports, compliance documentation, and regulatory logs
• Ensure adherence to safety standards, especially around high voltage systems, oxidizing gases, and confined spaces
• Train customers on system operation, routine maintenance, and safety procedures

Requirements

• Associate’s degree or technical certification in electrical, mechanical, environmental, or related field (or equivalent experience)
• 3–5 years of field service experience in water treatment or industrial equipment
• Hands-on experience with UV or ozone systems (or closely related technologies)
• Strong troubleshooting skills in electrical systems (high-voltage preferred), mechanical components, and basic PLC controls
• Familiarity with water disinfection principles and performance parameters (UV dose, CT concept)
• Ability to read P&IDs, wiring diagrams, and technical manuals
• Valid driver’s license and willingness to travel (75%)

Nice to have:

• Experience with electro-mechanical systems
• Knowledge of SCADA systems and remote diagnostics
• OSHA safety certifications (LOTO, confined space, electrical safety)
• Experience working with municipal or industrial disinfection systems

Benefits

• Medical, Dental, and Vision Insurance Starting Day 1
