Principal Process Engineer - Water

VVater is America’s Next Water Company, delivering the future of purification through its award-winning Farady Reactor (CES Best of Innovation 2025, World Future Award 2025, Time Best Invention Award 2025), proprietary ALTEP (Advanced Low Tension Electroporation Process), Advanced Dissolved Air Flotation, and Micro & Nano Bubble technologies. Unlike outdated chemical, filter, and membrane systems, VVater’s electric-field breakthroughs eliminate PFAS, microplastics, microorganisms, and other contaminants with record retention times, without toxic byproducts or costly consumables.

With over 4.3B gallons treated and validation from global leaders, VVater is scaling into municipal drinking water and wastewater, DPR/IPR, onsite reuse for data centers, commercial buildings, and resorts, residential purification, and consumer health water, delivering a 60% smaller footprint, 40% Cap Ex savings, 80% OpEx savings, and 40% less energy use.

The Process Engineer is the technical owner of VVater's treatment system designs. You will take a customer's raw water (or wastewater) characterization, the regulatory target, and the operating constraints, and you will design the entire system that gets from one to the other. Process flow diagrams. Piping and instrumentation diagrams. Mass balances. Hydraulic calculations. Equipment specifications. Bills of materials. Process control narratives.

We will be direct, because that is one of our values. This role is intense. VVater moves at a pace that is uncommon for the water industry. Designs come in fast. Customer deadlines are real. Commissioning happens when it happens, not when your calendar allows. We are not asking for someone to grind for the sake of grinding. We respect personal time when the operating tempo allows.

But this is a senior technical seat in a company moving at extraordinary speed, and the right person will be energized by that pace rather than depleted by it. If you want to design one plant a year and watch it slowly grind through permitting for 36 months, this is not your seat. If you want to design across every vertical of the water industry, see your systems built in months, and commission them in the field, this is exactly where you want to be.

• Design complete water and wastewater treatment systems from raw influent through finished water, across drinking water, wastewater, reuse, industrial, onsite, modular, recreational, and residential applications

• Produce process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), mass and energy balances, hydraulic profiles, and process control narratives

• Size and specify all major and minor equipment, pumps, blowers, tanks, vessels, electrochemical reactors, ADAF units, instrumentation, valves, piping

• Develop bills of materials (BOMs) and partner with procurement on vendor selection and equipment sourcing

• Perform process modeling and simulation as needed (GPS-X, Bio Win, WAVE, IMSDesign, custom spreadsheet and Python models)

• Optimize designs for Cap Ex, OpEx, footprint, energy, chemical use, and operability

• Design to applicable regulatory standards, EPA SDWA, EPA NPDES, NSF/ANSI 60 and 61, state primacy agency requirements (TCEQ and others), drinking water and wastewater discharge permits

• Support permitting documentation, regulatory submittals, and compliance demonstration testing

• Stay current on emerging regulations, PFAS rules, Lead and Copper Rule revisions, and evolving state DPR/IPR frameworks

• Work directly with the factory floor team to ensure designs are buildable and meet specifications

• Review fabrication, assembly, and FAT (Factory Acceptance…
