Plan, organize, manage, and execute Mechanical engineering projects under general supervision. Perform and oversee design work including modeling, calculations, drawings, and specifications, while preparing documentation, conducting design reviews, and supporting vendor compliance and field execution through construction and commissioning.

  • Plan, organize, manage, and execute mechanical engineering projects
  • Execute and oversee engineering design tasks (modeling, calculations, drawings, specifications)
  • Develop, prepare, and review technical documentation and reports
  • Conduct design reviews and evaluate vendor proposals for codes/standards compliance
  • Assist in resolving technical issues during construction and commissioning and improve design processes

This is a Mechanical and Piping engineering design role focused on producing deliverables such as PIDs, PFDs, piping isometric/orthographic drawings, equipment datasheets, BOMs, and EWPs. The role includes Caesar analysis capability, scoping and planning support with P6 schedules and budgets, and collaboration across multidisciplinary teams to integrate solutions into project plans.

The ideal candidate is a Senior Engineer with a Mechanical Engineering degree and 5+ years of related experience (or a Master’s with 3+ years). They are comfortable executing Mechanical and Piping engineering projects—producing and reviewing design deliverables like PIDs, PFDs, isometrics, BOMs, and EWPs—and supporting construction and commissioning with strong technical problem-solving.
