Staff Chemical Engineer - Water Systems and Chemistry

Jacuzzi Group is a leading global manufacturer of hot tubs, swim spas, baths, showers, saunas, and pool equipment. More than four thousand global employees work across our portfolio of brands, including Jacuzzi, Sundance Spas, Hydropool Swim Spas and Hot Tubs, DreamMaker, and more.

With manufacturing and warehouse operations in the United States, Canada, Mexico, Italy, the United Kingdom, France, Brazil, Chile, and Australia, we have more than 65 years of experience delivering innovative wellness products to our consumers across our many brands.

Jacuzzi Group is seeking a Staff Chemical Engineer to serve as the technical leader for water chemistry, water treatment, and water-system development across Jacuzzi Group's hot tub product portfolio, sitting within our cross-functional Engineering department and partnering daily with mechanical, electrical, controls, and manufacturing engineers, as well as Product Management, Quality, Regulatory, and external technology partners. This role owns the science behind how our hot tubs keep water clean, clear, and safe — from first-principles chemistry through field validation and post-launch monitoring.

This is a hybrid role based at our Chino, CA facility, with time split between office, engineering lab, and manufacturing/test floor on Mondays, Tuesdays, and Thursdays, and offers the ability to work remotely on Wednesdays and Fridays. Occasional domestic and international travel (up to ~15%) is expected to support supplier visits, contract labs, partner facilities, and trade events.

Who You Are

You are a rigorous, hands-on water chemistry engineer who reaches for first principles before received wisdom, and who takes genuine pride in the science behind a product that millions of people interact with daily. You can defend a test protocol to a skeptical engineering review and explain the same result to a marketing partner without losing either audience — and you're just as comfortable spinning up a test rig yourself as you are presenting findings to an executive team. You thrive in cross-functional environments, respect the constraints other disciplines bring to the table, and find solutions that work for the whole system, not just the chemistry.

What You'll Do

Water Chemistry & System Development

Own the technical roadmap for water sanitization, balancing, and treatment technologies — including chlorine, bromine, mineral systems, UV, ozone, AOP, salt/electrolytic chlorination, and emerging alternatives — across current and future spa platforms

Design and develop water-treatment subsystems in collaboration with mechanical and controls engineering, including filtration, dosing, circulation, and sensor integration

Translate water-chemistry science into engineering requirements, design inputs, and acceptance criteria that mechanical, electrical, and firmware teams can build to

Evaluate and recommend chemistries, media, and treatment technologies, balancing performance, cost, user experience, regulatory compliance, and long-term reliability

Test Protocol Development & Validation

Build rigorous, repeatable test protocols for water quality, sanitizer efficacy, oxidation performance, scale and corrosion behavior, filter loading, and long-term system durability under realistic bather-load conditions

Stand up and run lab and field studies, including accelerated aging, microbial challenge testing, sensor accuracy, and chemical compatibility with materials used in spa construction

Document test results in clear, audit-ready technical reports — protocols, raw data, statistical analysis, conclusions, and recommendations — supporting engineering decisions, regulatory submissions, and marketing claims

Define and maintain water-quality KPIs and the methods, instrumentation, and tolerances used to measure them

Cross-Functional Engineering & Product Partnership

Partner with Product Management to shape the water-experience roadmap, defining features, claims, and consumer benefits grounded in defensible chemistry and validated data

Collaborate with Mechanical, Electrical, Controls, and Firmware engineering on plumbing layouts, sensor placement, dosing hardware, automated control strategies, and user-facing water-management features

Work with Manufacturing and Supply Chain to ensure chemistries and components transition smoothly from prototype to production, including supplier qualification and incoming-quality criteria

Support Customer Care, Warranty, and Field Service on water-related issues, providing root-cause analysis, diagnostic guidance, and corrective action

Innovation & Technical Leadership

Lead innovation projects with outside technology partners, universities, and chemistry suppliers to evaluate next-generation water-treatment platforms, including advanced oxidation, novel sanitizers, smart-sensing, and sustainability initiatives

Monitor and interpret the external landscape, including competitor approaches, emerging research, regulatory shifts, and consumer trends
