Water Quality Field Service Engineer

HOH Water Technology is a third-generation, family-owned water treatment company proudly celebrating over 58 years in business. Our success has always been about more than water treatment — it is about investing in people and creating lasting impact for our clients, coworkers, and community. We believe our people are our greatest competitive advantage, and we have built a culture centered around our Core Values of Accountability, Creativity, Teamwork, and Service.

We are looking for a Water Quality Engineer who wants to make a measurable impact for clients by solving water treatment challenges, improving system performance, and helping protect critical equipment and operations.

• This is a hands-on, client-facing engineering role focused on industrial and commercial water treatment systems.
• You will evaluate water quality, troubleshoot treatment programs, interpret test results, and recommend solutions that improve reliability, efficiency, safety, and sustainability.
• You will partner closely with customers, sales, service, and operations teams to ensure water treatment programs are performing as designed and delivering meaningful value.
• You will manage and grow ongoing customer relationships by maintaining regular contact, understanding customer needs, and taking ownership of follow-up items that strengthen long-term account success.
• If your greatest satisfaction comes from solving technical problems, building trust with customers, and turning data into practical action, we would love to meet you.
• Must be able to report to our Palatine, Illinois office only when needed, and travel daily to customer locations throughout the region.

What We Offer

• Competitive Compensation: Competitive salary based on experience of $85,000-$120,000.
• Comprehensive Benefits: Medical and Dental Insurance with generous employer contributions, HSA contributions ($1,200 family / $800 individual annually), 401(k) with company matching, Life Insurance, and much more.
• Generous Time Off: 15 PTO days, 16 paid holidays including extended holiday pay at the end of the year.

• Career Growth: Ongoing professional development, hands-on technical learning, continuing education reimbursement, and the opportunity to grow your expertise in water treatment, engineering, and customer partnership.

You’ll Love This Role If...

• You enjoy solving technical problems. You like digging into data, asking smart questions, identifying root causes, and developing practical solutions that work in real-world systems.
• You care about water quality and system performance. You understand that reliable water treatment protects equipment, improves efficiency, reduces risk, and helps customers operate with confidence.
• You are comfortable with customers. You can explain technical information clearly, build credibility through follow-through, and help customers understand what is happening and why it matters.
• You are detail-oriented. Test results, trend data, site observations, and documentation matter to you because small details often lead to the right recommendation.
• You like variety. One day may involve analyzing water samples and treatment data; another may include walking a customer site, troubleshooting a system, or supporting a new program rollout.
• You are proactive and resourceful. You notice issues early, communicate clearly, and take ownership of moving solutions forward with urgency and care.
• You value teamwork. You enjoy working with service technicians, sales professionals, operations teammates, and customer contacts to deliver excellent outcomes.
• You want your work to matter. You are motivated by helping customers protect critical assets, improve reliability, and make informed decisions about their water treatment programs.

What You’ll Be Doing

• Assess industrial and commercial water treatment systems, including boilers, cooling towers, closed loops, pretreatment equipment, and related applications.
• Collect, review, and interpret water testing data, operating conditions, trends, and field observations to evaluate program performance.
• Troubleshoot water quality issues and recommend corrective actions related to scale, corrosion, microbiological control, efficiency, and equipment protection.
• Prepare clear technical reports, summaries, and recommendations for customers and internal teams.
• Collaborate with sales, service, and operations teams to design, optimize, and support effective treatment programs.
• Manage an assigned book of customer accounts by maintaining regular contact, understanding customer needs, building relationships with key decision makers, and ensuring follow-up items are completed.
• Identify opportunities to strengthen and grow customer accounts through upgrades, cross-selling, process improvements, and proactive recommendations that improve customer outcomes.
• Visit customer sites to support testing, troubleshooting, program reviews, training, surveys, and continuous improvement opportunities.

• Water treatment programs perform as intended, with issues identified early and resolved proactively.
• Internal teams have the technical insight and documentation they need to serve customers with excellence.
• Reports, recommendations, and follow-ups are timely, accurate, and easy for customers to understand.
• You help strengthen long-term customer relationships by combining technical expertise with HOH’s commitment to service and care.
