Project Engineer

The Project Engineer is a highly experienced contributor who independently owns significant portions of project engineering scope on complex ultrapure water (UPW) and process utility projects. This role is considered a technical expert in one or more areas of project engineering and a trusted resource across the project team.

The Project Engineer works autonomously with minimal oversight, interfaces directly with customers, A&E firms, general contractors, and internal global engineering teams, and is responsible for the technical quality, execution, and integration of their assigned scope. In addition to delivering high‑quality engineering work, this role actively mentors junior engineers, supports system startup and troubleshooting, and contributes to the development and implementation of engineering standards.

HERE'S WHAT YOU WILL DO:

• Own Project Engineering scope for small to medium U.S. projects and defined portions of large or international projects, serving as the primary technical point of contact for assigned scope

• Execute engineering work independently with minimal supervision and minimal errors, ensuring technical quality and schedule adherence

• Specify, size, select, review, and approve equipment including pumps, tanks, pressure vessels, heat exchangers, control valves, and associated components

• Review and approve equipment purchases and vendor submittals within assigned scope

• Lead or support BIM and interconnect piping coordination, including review of third‑party models, shop drawings, and clash resolution

• Maintain and manage Plant Data Manager (PDM) databases and associated project engineering documentation

• Coordinate with third‑party consultants and vendors for seismic, structural, and specialty engineering analyses

• Maintain project‑specific pipe class documents and coordinate with global standards teams to ensure alignment

• Interface directly with customers, A&E firms, general contractors, vendors, and internal global engineering teams

• Support fabrication, installation, startup, commissioning, and operational troubleshooting activities as required

• Provide technical guidance, mentoring, and work review for junior project engineers

• Assist Engineering Management and global teams with development, refinement, and implementation of engineering standards and best practices

YOUR QUALIFICATIONS WILL INCLUDE:

• Proficiency in MS Suite

• Proficiency in AutoCAD Plant3D

• Working knowledge of Revit

• Knowledge of equipment sizing and specification including pumps, pressure vessels, valves, etc.

• Knowledge of water treatment technologies including filtration, membrane treatment, ion exchange treatment, and reclaim water treatment.

EDUCATION, TRAINING AND EXPERIENCE YOU’LL POSSESS:

• B.S. degree in the mechanical or chemical engineering discipline from an accredited university or other related qualified training.

• Typically 5–10+ years of relevant project engineering experience in design‑build, EPC, or complex industrial process systems.

• Demonstrated ability to execute independently, lead defined scopes, and deliver high‑quality engineering with minimal supervision.

• Strong understanding of UPW/process utility systems, equipment design, piping systems, BIM coordination, and installation practices.

WILL I NEED TO TRAVEL:

• Some travel may be required to support project construction. Maximum of 10% travel, up to two weeks at a time in the US.
