Collaboration with environmental engineers, lab technicians, and regulatory agencies is common to address complex water quality issues and report findings efficiently.

Job description

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.
About the Role
  • 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.
  • Profit Sharing Bonus: Company Profit Sharing Bonus (budget projection for 2026: approximately 3-4 weeks of additional pay).
  • Engaging Culture: Caring leaders who invest in people. HOH earned a 4.69/5 Gallup Employee Engagement Q12 score, and we believe in celebrating wins, giving back, and creating meaningful connections through team and company events.
  • 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.

What Success Looks Like
  • Customers trust HOH's recommendations because they are grounded in strong analysis, clear communication, and practical solutions.
  • 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.

Why HOH?
At HOH, you will work alongside leaders who genuinely care about people and believe business should leave a lasting impact. We invest heavily in our employees through professional development, industry-leading engagement, generous benefits, profit sharing, and a culture where people know they matter.
  • If you are looking for a role where your engineering mindset, curiosity, and customer focus will directly improve water treatment outcomes, we would love to meet you.
  • We do not just want someone to fill this role - we are looking for someone who wants to become an important part of our story.

Requirements
  • Bachelor's degree in Chemical Engineering, Environmental Engineering, Mechanical Engineering, Chemistry, or a related technical field required.
