• May lead project-specific engineering teams and coordinate plumbing engineering work assignments to support successful project delivery.

• Lead the design and production of plumbing engineering deliverables, including drawings, specifications, calculations, hydraulic analyses, and technical documentation throughout the project lifecycle.

• Design domestic water, sanitary waste and vent, storm drainage, natural gas, medical gas, specialty piping, and other plumbing systems in accordance with applicable codes, standards, and project requirements.

• Perform plumbing system sizing and hydraulic calculations, fixture unit analyses, equipment selection, and utility demand evaluations.

• Coordinate plumbing system layouts with HVAC, structural, architectural, electrical, fire protection, and civil disciplines to ensure fully integrated and constructible building designs.

• Prepare and review coordinated 2D drawings and 3D models using computer-aided design (CAD) and Building Information Modeling (BIM) platforms.

• Review plumbing engineering deliverables to ensure compliance with project quality standards, coordination requirements, constructability expectations, and applicable plumbing codes.

• Lead construction administration activities, including reviewing shop drawings and submittals, responding to Requests for Information (RFIs), conducting site visits, evaluating field conditions, and supporting commissioning and project closeout activities.

• Collaborate with architects, engineers, contractors, utility providers, authorities having jurisdiction (AHJs), and project stakeholders to develop coordinated and cost-effective plumbing solutions.

• Assist project managers with scope management, budgeting, scheduling, technical risk evaluation, and quality control related to plumbing system design.

• Apply sound engineering judgment to resolve complex plumbing design challenges while balancing performance, maintainability, sustainability, and lifecycle costs.

• Support the evaluation and implementation of sustainable water management strategies, including water conservation, rainwater harvesting, graywater reuse, and other high-performance building initiatives where applicable.

• Participate in professional development activities and contribute to continuous improvement of engineering standards, design processes, and technical best practices.

• Bachelor's degree in Mechanical Engineering (or equivalent engineering discipline with a plumbing engineering focus) required.

• 6+ years of experience in plumbing engineering for commercial, institutional, healthcare, industrial, or mission-critical building projects required.

• Professional Engineer (PE) license required.

• Active NCEES Record for licensure maintenance preferred.

• Demonstrated experience designing domestic water, sanitary, storm, natural gas, medical gas, specialty piping, and other plumbing systems for commercial building projects.

• Strong understanding of the International Plumbing Code (IPC), Uniform Plumbing Code (UPC), NFPA standards, local jurisdictional requirements, and applicable building codes.

• Proficiency with plumbing engineering calculations, hydraulic analysis, CAD/BIM software, and industry-standard engineering design tools.

• Experience coordinating plumbing systems within multidisciplinary BIM environments and participating in clash detection and constructability reviews.

• Strong knowledge of construction administration practices, submittal review, field coordination, and project delivery methods.

• Excellent analytical, communication, collaboration, and problem-solving skills.

• Ability to effectively manage multiple projects and priorities while working independently and as part of a multidisciplinary team.
