Sensorex Summary

At Sensorex, we believe that even the most complex water analysis should be fast and simple to perform. Sensorex specializes in the design and manufacture of pH and ORP electrodes, conductivity and TDS sensors, and other electrochemical and optical measurement technologies. We’ve introduced some leading edge technologies since our initial launch in 1972, and today, we remain focused on the continual advancement of water quality monitoring products.

Trusted by over 250 market leaders in water treatment applications, Sensorex offers industry leading sensor development services alongside application advisory services. With our strong legacy of supporting OEMs through custom offerings, as well as domestic and international distribution partners, we deliver a seamless buying experience and fast delivery. In addition to our factory and headquarters in Garden Grove, California, United States, Sensorex also has manufacturing capability in Czech Republic in support of our European customers. We offer localized support with sales and customer service representatives based in UK and Czech Republic.

Sensorex is a subsidiary of Halma plc (“Group”) under the Environmental & Analysis Sector. Halma plc is listed on the London Stock Exchange whose purpose is to grow a safer, cleaner, healthier future for everyone every day! Halma plc has a current market capitalization of approximately £7 billion. The group has 50 businesses operating through three sectors (Healthcare, Environmental & Analysis, and Safety) in more than 20 countries and major operations in Europe, North and South America and Asia, supplying customers in 160 countries and employing more than 6,600 people worldwide.

The Product Specialist is a subject matter expert on Sensorex's products and applications, and the primary resource for customers, sales partners, and internal teams who need deep product knowledge. The Product Specialist works at the intersection science & engineering, product documentation, and market-facing support.

While onboarding this person will have the mentorship of a colleague who has spent nearly three decades building the product knowledge base at Sensorex, with the goal of ultimately becoming the long-term custodian of that institutional knowledge. The ideal candidate is a scientist or engineer by training who is equally comfortable calibrating a pH electrode in a lab, writing a technically rigorous user manual, and advising a water treatment engineer on sensor selection. Over time, this role offers a natural growth path — toward deeper specialization as a subject matter expert and product authority, or toward broader product management responsibilities with commercial scope, depending on the individual's strengths and interests.

Key Responsibilities

Technical Support & Application Expertise:

• Serve as the primary resource for inbound technical inquiries from OEM customers, system integrators, distribution partners, and end users.
• Troubleshoot sensor performance issues across a range of measurement parameters (pH, ORP, conductivity, dissolved oxygen, free chlorine, etc.) and application environments.
• Provide application guidance to help customers select the right product for their specific process conditions, including media chemistry, temperature and pressure ranges, installation configuration, and output interface requirements (4-20mA, Modbus/RS-485, SCADA integration).
• Support the sales team with pre-sales technical consultation, including participating in customer meetings or demos when product expertise is required.
• Development of a technical support case management process that will serve as an informational resource for sales and product management.
• Systematically capture and synthesize feedback from customers, technical support interactions, and field conversations to surface product improvement opportunities and unmet needs.
• Work with product management and R&D to translate customer insights into actionable product feedback — advocating for changes to specifications, features, or accessories based on observed application requirements.
• Monitor competitive products, industry standards, and evolving regulatory requirements to inform the product team about market trends relevant to Sensorex's portfolio.
• Participate in trade shows, industry events, and customer site visits as a credible technical representative of the Sensorex brand.

Product Content Management:

• Own the accuracy, currency, and quality of Sensorex's product documentation portfolio, including specification sheets, datasheets, instruction manuals, installation guides, and application notes.
• Work with engineering and R&D to ensure that new and revised products are accompanied by complete, accurate, and professionally presented documentation before market release.
• Develop supplementary technical content including application notes, selection guides, and comparison matrices that help customers navigate the product portfolio.
• Maintain documentation standards and ensure consistency in technical language, specification format, and regulatory or compliance references across all product literature.

• Develop technically grounded content for web, trade publications, and campaigns — translating complex electrochemistry into accessible, compelling language for varied audiences.
• Support the creation of training materials, product presentations, and application-specific content that helps the sales team and distributor network sell more effectively.

Required Qualifications

• Associate’s degree or higher in Chemistry, Engineering, Environmental Science or related field.
• 3+ years of hands-on experience developing, deploying, or validating water quality sensors, including pH, dissolved oxygen, chlorine, nitrate, or other electrochemically detectable analytes.
• Customer-facing communication skills — comfortable presenting technical material to engineers, operators, and procurement professionals alike.
• Experience reading and interpreting technical specifications, wiring diagrams, and instrument communication protocols (4-20mA, Modbus/RS-485).
• Exceptional written communication skills, with the ability to produce technically rigorous documentation that is also clear, well-organized, and accessible.

Preferred Qualifications

• Experience in one or more of Sensorex's key end markets: municipal water and wastewater treatment, industrial process water, pool & spa, aquaculture, food and beverage, or laboratory analytics.
• Strong understanding of redox chemistry, electrode materials, electrolyte systems, and electrochemical interfaces.
• Exposure to SCADA/PLC integration or building automation systems in the context of sensor signal management.
• Experience writing or editing technical documentation — specification sheets, application notes, or product manuals.

Compensation

• Competitive base salary ($75-$85k)
• Competitive benefits package including 401K
• Annual bonuses based on profit growth of the company
