Senior Mechanical Systems & Applications Engineer

Job Description: At Aquatech, we tackle the challenges of water scarcity and complexity by leveraging technology, expertise, and financing to deliver comprehensive solutions that reduce carbon and recycled water footprint. As a leading global provider of water and process technology solutions, we help the world's most recognized companies achieve their sustainability and operational goals by implementing innovative approaches for water reuse, desalination, minimal and zero liquid discharge, and critical minerals recovery. Our work catalyzes the transition toward a more sustainable future and showcases our commitment to addressing water's role in climate adaptation. Aquatech immediately needs a full-time Senior Mechanical Systems & Applications Engineer to work in our Albany, Oregon office. The hours of this position are Monday - Friday, 8:00 am to 5:00 pm. This role is responsible for leading product development, membrane production, application testing, and engineering support for advanced flat-sheet membrane technologies, including Forward Osmosis (FO), nanofiltration (NF), seawater reverse osmosis (SWRO), and osmotically assisted reverse osmosis (OARO) membranes with low salt rejection characteristics.

Mechanical System Design & Integration: Develop and refine mechanical designs for membrane modules, skids, pilot systems, test fixtures, piping arrangements, and related balance-of-plant equipment. Translate process requirements into equipment layouts, component specifications, bills of materials, drawings, calculations, and design documentation. Integrate pumps, pressure vessels, valves, instrumentation, piping, controls interfaces, and membrane components into complete systems. Perform design reviews focused on safety, operability, maintainability, manufacturability, reliability, and cost. Coordinate with internal engineering staff, suppliers, fabricators, and manufacturing partners to move designs from concept through release and implementation.

Applications Engineering: Evaluate customer and project requirements to determine the technical fit of FO, OARO, RO, NF, and related membrane solutions. Support process and system sizing, equipment selection, operating-envelope definition, pretreatment considerations, and proposal-level technical development. Partner with sales and business teams to clarify requirements, identify technical risks, and communicate practical solution options. Prepare technical inputs for proposals, customer discussions, design reviews, and internal decision-making.

Testing, Piloting & Field Support: Develop test plans and support laboratory, pilot, and field testing of membrane systems and applications. Analyze operating data, document results, identify failure modes, and recommend design or operating improvements. Support commissioning, troubleshooting, and performance verification at customer, partner, and pilot locations. Travel domestically and internationally, including occasional short-notice travel, based on project and customer needs.

Production & Product Support: Provide engineering support for membrane module and element production, including work instructions, fixtures, quality criteria, and technical issue resolution. Coordinate production and element-rolling activities performed by internal teams or external manufacturing partners. Support changes that improve consistency, yield, assembly, testability, and product readiness. Maintain clear technical documentation and support controlled release of drawings, specifications, work instructions, and product updates.

Cross-Functional Technical Leadership: Lead assigned technical workstreams and coordinate contributors without broad site or departmental management responsibility. Provide subject-matter guidance to engineering, operations, sales, and field teams on membrane system design and application issues. Contribute technical information to invention disclosures, product documentation, and intellectual property activities as requested. Manage priorities, risks, and deliverables for assigned projects and communicate constraints early.

Benefits: Aquatech offers a comprehensive benefits package, including paid time off, company-paid holidays, and a 401K plan (all benefits are based on eligibility).

Essential Functions: To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed above and below are representative of the knowledge, skill, and/or ability required. Reasonable accommodations may be made to enable individuals with disabilities to perform essential functions. Physical Job Demands: Exerting up to 10 pounds of force occasionally and/or a negligible amount of force frequently or constantly to carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, limited walking, and standing.

Qualifications: Bachelor's degree in Mechanical Engineering or a closely related engineering discipline. Progressive experience designing and integrating industrial equipment, fluid-handling systems, process skids, or membrane-based systems. Working knowledge of pumps, piping, valves, pressure-containing equipment, instrumentation, materials of construction, and mechanical design practices. Experience creating or reviewing equipment layouts, fabrication drawings, schematics, P&IDs, bills of materials, and technical specifications. Ability to troubleshoot equipment and system performance using field observations, test data, and structured engineering analysis. Ability to communicate effectively with customers, suppliers, fabricators, operations personnel, and multidisciplinary engineering teams. Ability to travel domestically and internationally, including occasional short-notice travel, and maintain documentation required for such travel. Must be able to work 100% on-site in Albany, Oregon.
