• Size and select pumps, membranes, pressure vessels, filters, valves, instrumentation, piping, and related equipment.

• Review customer specifications and develop compliant technical solutions.

• Support preparation of technical proposals and customer clarification responses.

• Work directly with production personnel during system fabrication and testing.

• Document legacy systems and support continued development of standardized designs.

• Provide technical support for field service and existing equipment.

• Bachelor's degree in Mechanical, Chemical, Environmental, or related engineering discipline.

• 7+ years of relevant engineering experience preferred.

• Experience with reverse osmosis, desalination, industrial water treatment, process equipment, packaged systems, or similar equipment strongly preferred.

• Strong understanding of pumps, piping, valves, pressure vessels, instrumentation, and process equipment.

• Ability to read and develop P&IDs and engineering drawings.

• Experience taking engineered equipment from design through fabrication and commissioning.

• Strong troubleshooting and problem-solving abilities.

• Comfortable working directly with production personnel and customers.

• Ability to independently manage engineering assignments and priorities.

• Strong communication and documentation skills.

• Willingness to travel periodically for commissioning, service, and customer support.

• Experience with seawater RO, marine equipment, military/government projects, municipal water treatment, electrical controls, PLC-based systems, or AutoCAD is a plus.

We are looking for an experienced engineer who enjoys working on real equipment and managing projects beyond calculations and drawings. The successful candidate will be comfortable moving between engineering design, production environments, customer meetings, factory testing, and field commissioning.

This position offers substantial technical responsibility and the opportunity to become a key member of an experienced engineering and manufacturing organization.
