Mesa Associates is seeking a Mechanical Engineer to join our team working closely with our Principal Mechanical Engineer and building bench depth alongside our Senior Mechanical Engineer. This is a hands-on design role: you will be doing piping and pressure vessel design work day to day not just supporting others with senior guidance available along the way. Prior HVAC exposure is a plus but not required. We value a strong work ethic and a positive coachable attitude as much as technical skill.

What Were Looking For

• Solid working knowledge of ASME B31.1/B31.3 piping codes and familiarity with ASME Boiler & Pressure Vessel Code Section VIII fundamentals
• Comfortable sizing routing and specifying piping for power or industrial applications including basic material selection and wall thickness calculations
• Growing experience with piping stress analysis tools such as AutoPIPE and/or Caesar II
• Proficient computer skills including Microsoft Office Suite; familiarity with Plant3D AutoCAD MicroStation or SolidWorks preferred

What Youll Do

• Perform piping design sizing and routing tasks under senior engineer guidance
• Prepare engineering designs and supporting documents including calculations drawings and specifications for piping and pressure vessel scopes
• Support process calculations such as flow rate pressure drop and line sizing directly within the Mechanical Engineering group; Mesa does not have a separate Process Engineering function so this work sits with Mechanical
• Perform walkdowns and collect field data on existing piping and pressure equipment

What Were Looking For

• Any exposure to industrial HVAC design load calculations or ductwork sizing is a plus though not required to be considered for this role

What Youll Do

• Support HVAC-related scopes as interest and experience allow working alongside the Senior Mechanical Engineer (Generalist)

• Work closely with the Principal Mechanical Engineer (Piping & Pressure Systems) who will check your work verify code compliance and provide mentorship and support though youll own and execute your own design assignments day to day
• Collaborate with the Senior Mechanical Engineer (Generalist) on shared or HVAC-adjacent scopes
• Build deep piping and pressure system design skills as the primary focus with optional growth into HVAC over time
• Bring energy curiosity and a willingness to learn with the expectation of taking on more ownership and eventually mentoring junior engineers as experience grows

• Bachelors degree in Mechanical Engineering (required)
• 5 to 10 years of experience in piping design ideally in power generation or industrial environments
• Comfortable performing design calculations and producing deliverables independently with senior review
• HVAC design exposure is a plus not required
• Strong written and verbal communication skills; works well across multi-discipline project teams
• Well organized curious and quick to spot issues and offer practical solutions
• A positive team-first attitude and a genuine willingness to pitch in wherever the team needs it
