Job description

#jobalert | DIRECT HIRE | MECHANICAL ENGINEER | INDUSTRIAL EQUIPMENT MANUFACTURING | Tulsa, OK area

Our client manufactures custom-engineered equipment for oil & gas applications and advanced manufacturing facilities. They're adding a Mechanical Engineer to a tenured team to keep pace with project volume. You'd own projects end to end — initial customer quote through detailed design and fabrication support. A hands-on seat, not one narrow piece of a much larger machine.

• Anticipated $110K-$150K, dependent on experience level
• Full suite of benefits: Health/Dental/Vision, HSA, Life, etc.
• Employee Stock Ownership Plan (ESOP)

Key Responsibilities

• Evaluate customer-supplied data (3D CAD files, drawings, scopes of work, quality documents) to define engineering requirements for quoting and detailed design.
  
• Develop and redline P&IDs to communicate project requirements to estimating and drafting.
  
• Perform equipment sizing calculations using process simulation software and in-house engineering tools.
  
• Perform code calculations for pressure vessels, piping, control valves, relief valves, and pressure regulators.
  
• Review and approve 3D models and drawings for assigned projects against engineering standards.
  
• Engage directly with customers, project managers, and the commercial team to resolve scope gaps and flag scope changes.
  
• Own assigned projects from the proposal/quote stage through detailed engineering and into fabrication support.
  
• Work across mechanical, process, and structural considerations rather than one narrow discipline.

Skills & Experience

• Bachelor's degree in Mechanical, Chemical, Petroleum, Electrical, or Instrumentation Engineering from an ABET-accredited university — or equivalent hands‑on design/engineering experience for candidates with 15+ years in the field.
  
• 3-5+ years of engineering experience in a manufacturing environment producing engineered‑to‑order equipment.
  
• Working knowledge of ASME, API, NFPA, and ANSI codes and standards.
  
• Experience specifying and designing process control systems combining pneumatic, electro‑mechanical, and electronic devices.
  
• Experience applying NFPA requirements for electrical area classification.
• Direct experience with pressure vessel and piping code calculations in a fabrication‑shop setting, not a pure design/consulting environment.
• Comfort working across disciplines — mechanical, process, and enough structural/electrical judgment to keep a project moving without handoffs to multiple specialists.
• Experience owning a project from proposal/quote through fabrication support, rather than handing it off after design.
