Principal Mechanical Engineer

Mesa Associates is seeking a Principal Mechanical Engineer to serve as the senior advisor for our Piping & Pressure Systems practice, delivering projects for our Generation, Industrial, and Government clients. This role is centered on review and guidance rather than day-to-day design production: you will bring deep piping and pressure vessel expertise and strong power industry experience to catch issues, verify code compliance, and steer engineers across the department toward sound technical decisions, rather than producing the bulk of the designs yourself. We're looking for someone who leads by example, communicates clearly, and genuinely enjoys helping others get it right.
