• Work closely with the sales team to provide timely upfront engineering support, technical proposals, calculations, drawings, and specifications needed to win projects.
• Write clear, professional technical specifications and submittals for consulting engineers and project bids.
• Select equipment, components, and instrumentation based on process requirements, water chemistry, compatibility, and performance goals.
• Specify instrumentation (signals, loops, analytical devices) and integration approaches for SCADA/PLC control systems.
• Apply water chemistry knowledge and process control principles to ensure systems achieve desired outcomes.
• Manage multiple projects and priorities simultaneously in a dynamic, high-volume environment while maintaining accuracy and quality.
• Support internal fabrication and systems integration with clear, buildable engineering packages.
• Serve as a technical resource to both internal sales and external consulting engineers.

Requirements

• Bachelor’s degree in Chemical, Mechanical, or Environmental Engineering, or related Engineering discipline (or equivalent practical experience).
• 5–10+ years designing or supporting chemical feed, chemical dosing, or process systems (municipal water/wastewater experience strongly preferred).

• Solid understanding of instrumentation, control signals, and SCADA/PLC integration.
• Working knowledge of water/wastewater chemistry and chemical handling best practices.
• Demonstrated ability to deliver engineering support under time pressure for sales opportunities.
• Strong technical writing and communication skills (specs, calculations, submittals).
• Excellent multitasking and project management skills in a fast-paced setting.

Preferred Qualifications

• Direct experience supporting sales efforts or working with manufacturer’s representatives / consulting engineers in the water industry.
