Controls Engineer with Ozone

Pinnacle Ozone Solutions is a leader in advanced ozone generation systems for water and air treatment. Based in Cocoa, Florida, we design, manufacture, and support modular, high-efficiency ozone systems powered by our patented QuadBlock® technology. Our complete systems serve municipal drinking water, industrial wastewater, aquaculture, potable reuse, and air purification applications across the United States and Canada. We are ISO 9001:2015 certified and operate an in-house UL 508A listed Industrial Control Panel manufacturing facility.

We are seeking a Controls Engineer who is passionate about designing, programming, and commissioning industrial control systems for ozone generation and process equipment. This role requires a broad controls background combined with the ability to focus on the unique demands of ozone systems—precision residual control, safety interlocks, thermal management, gas handling, and reliable long-term operation. Ideal candidates are “jack-of-all-trades and master of a few,” with strong problem-solving skills and a drive for continuous learning.

How You Make an Impact
• Design, develop, and implement control systems for complete ozone generation platforms, including generators, chillers, oxygen feed systems, injection skids, off-gas destruct, and associated process equipment.
• Program and configure PLC logic (ladder logic, function block, structured text) and HMI/SCADA interfaces to deliver precise Ozone-On-Demand® control, PID residual (dissolved ozone / ORP) loops, sequence control, alarms, and safety interlocks.
• Perform engineering calculations to size and select components critical to ozone systems—pumps, valves,
chillers/heat exchangers, and related fluid systems—including thermal analysis and pressure-drop calculations for both compressible (oxygen/ozone) and incompressible fluids.
• Collaborate with project managers, mechanical/electrical engineers, technicians, and fabricators to ensure on-time, successful project delivery from design through factory testing and field commissioning.
• Conduct testing, validation, and commissioning of control systems both in-house and at customer sites to verify
functionality, reliability, and process performance.
• Create clear control system documentation including control narratives, test procedures, O&M manuals, and as-built drawings.
• Interface professionally with customers as a technical representative of the company during design reviews, factory acceptance tests, and commissioning.
• Identify potential operational or reliability issues and contribute to product redesigns and continuous improvement of both hardware and software.

Requirements and Skills
• Must be a US Citizen

* Bachelor’s degree in Electrical Engineering, Controls Engineering, Mechatronics, or a related field.
• Prefer 3+ years of hands-on experience with PLC programming (ladder logic, function block, and structured text). Experience with Schneider Electric Modicon platforms is a strong plus; other major platforms (Allen-Bradley, Siemens,
etc.) are valued.
• HMI and SCADA network programming experience (Red Lion, Ignition, or similar preferred).
• Familiarity with sizing and thermal analysis of chillers and heat exchangers used in process cooling.
• Ability to perform pressure-drop calculations for compressible and incompressible fluids to support system design.
• Knowledge of integrated industrial control system components including power supplies, transformers, motor
controls/VFDs/soft starters, contactors/relays, and process instrumentation (flow, pressure, temperature, dissolved ozone, ORP, ambient ozone, oxygen purity) and safety interlocks.
• Ability to read and interpret electrical schematics, mechanical drawings, and P&IDs.
• Excellent written and verbal communication skills with both technical and non-technical audiences.
• Strong analytical and problem-solving skills with attention to detail and system-level thinking.
• Willingness to travel occasionally for commissioning and customer support (primarily domestic).

Salary is based on experience and alignment with the requirements above.
