Senior Application Engineer - Ultrapure Water & Microelectronics

The position can be remote. This individual can work anywhere in North America.

Note: This is a mechanical/chemical process engineering role within industrial water treatment. Candidates must have direct experience in high-purity water, UPW systems, or semiconductor water infrastructure.

As an Sr. Applications Engineer, you'll be the first technical point of contact for our clients, partnering with Sales and Process Engineering to develop innovative water treatment solutions for complex, mission-critical applications. You'll own the complete proposal lifecycle—from lead qualification through system design, costing, and contract handover—while collaborating across global teams and time zones.

What You'll Do

Design & Engineering

• Leverage expertise in mass transfer, fluid dynamics, and inorganic chemistry to design custom ultrapure water (UPW) systems
• Work across a diverse equipment portfolio including ultrafiltration, reverse osmosis, UV destruction, electrodeionization, and ion exchange technologies
• Develop process flow diagrams, mass balances, equipment selections, and system layouts with Process Engineering

Proposal Leadership

• Own proposal schedules and coordinate resources across engineering teams
• Manage vendor and subcontractor relationships throughout the proposal cycle
• Evaluate technical specifications, manage scope changes, and ensure on-time delivery
• Collaborate with other engineering disciplines (electrical, mechanical, etc.) to develop comprehensive proposal packages

Client Engagement

• Create compelling proposal documents that showcase Veolia's superior process designs and integrated solutions
• Support Sales with technical consultations and customer presentations
• Translate complex engineering into clear client communication.
