  • Perform and check calculations to support sizing of mechanical systems equipment and components.
  • Analyze and determine piping systems design conditions.
  • Develop Piping & Instrumentation Diagrams and coordinate with design engineers, system engineers, and test engineers for input and review.
  • Develop procurement packages (specifications, statements of work, datasheets, etc) and provide engineering guidance to support the procurement of pumps, valves, heat exchangers, pressure vessels, or other hardware necessary for the fabrication and installation of the proposed design.
  • Review vendor specifications, drawings, and equipment documentation.
  • Lead development of estimates (cost and schedule) for design deliverables.
  • Provide guidance to and check the work of less experienced engineers.
  • Support development of procedures and guidelines for standardization of work processes.
  • Coordinate with the appropriate system engineer, craft supervisor, and/or work planner to ensure that hardware is fabricated and installed in accordance with the approved design package.
  • Participates in and fosters a work environment that is based upon openness, trust, communication, teamwork, empowerment, innovation, and satisfaction.
