About the role

Key responsibilities & impact

**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
- Serve as the in-house subject-matter expert on water chemistry; coach engineers, technicians, and product managers; and represent the company in technical forums and with key customers
- Support intellectual-property strategy by identifying novel approaches, contributing to invention disclosures, and providing technical depth for patent filings

Requirements

What you’ll need

**What You Bring**
*Required*
- Bachelor's degree in Chemical Engineering, Chemistry, Environmental Engineering, or a closely related discipline from an ABET-accredited program
- 5+ years of progressively responsible experience in water testing, water-system development, and water-chemistry management, ideally within the pool and spa or drinking-water filtration industry
- Demonstrated, hands-on expertise with sanitizer chemistry (chlorine, bromine, mineral, UV, ozone, AOP, electrolytic systems), water balance, scale and corrosion control, and microbial control
- Proven ability to design, write, execute, and document formal test protocols (DOE, accelerated life, efficacy, compatibility) and draw defensible conclusions from data
- Strong working knowledge of analytical methods and instrumentation for water quality (spectrophotometry, titration, ion chromatography, ORP/pH/conductivity probes, microbial assays)
- Strong written and verbal communication skills
- Demonstrated ability to manage competing priorities with strong attention to detail.
*Preferred*
- Experience in a private equity-backed, high-growth, or global manufacturing environment
- Direct experience developing or qualifying products to NSF/ANSI 50, 60/61, 53/42/55/58, or APSP/PHTA standards
- Working knowledge of EPA pesticide registration (FIFRA) and familiarity with relevant state and local health-department spa regulations
- Experience with electrolytic chlorine generation, AOP, membrane filtration, or IoT-enabled water-monitoring platforms
- Experience designing or qualifying test cells, flow loops, and lab automation
- Prior experience working with external R&D partners, chemistry suppliers, contract labs, or academic institutions on joint development programs
