• Important: Direct experience designing mud pumps, positive displacement pumps, frac pumps, or closely related equipment is required.

Key Responsibilities:

• Design, develop, and improve mechanical equipment, pump systems, and related components.
• Create detailed engineering drawings, design layouts, and 3D models using CAD software.
• Perform stress analysis and finite element analysis (FEA) to evaluate component strength, durability, and reliability.
• Conduct tolerance studies and review engineering drawings and technical documentation for accuracy and quality.
• Research, evaluate, and specify purchased components based on performance, compatibility, and cost.
• Develop test plans and validate component and system performance.
• Prepare engineering reports documenting design calculations, analyses, testing, and results.
• Interpret P&IDs, electrical schematics, and hydraulic schematics to support equipment design and integration.
• Collaborate with manufacturing, engineering, and other cross-functional teams throughout equipment conceptualization, development, and production.
• Ensure designs align with applicable engineering standards, safety requirements, and industry specifications.
• Stay current with engineering technologies, materials, and design methods to support continuous product improvement.

Required Qualifications:

• Bachelor's degree in Mechanical Engineering.
• At least 3 years of mechanical design engineering experience; 5 or more years preferred.
• Required pump design experience involving mud pumps, positive displacement pumps, frac pumps, or closely related equipment.
• Demonstrated experience in machine design and mechanical system development.
• Proficiency with CAD software such as Creo, Autodesk Inventor, or SolidWorks.
• Experience with FEA tools such as ANSYS or SolidWorks Simulation.
• Ability to read and interpret engineering drawings, P&IDs, and electrical and hydraulic schematics.
• Strong analytical, troubleshooting, and problem‑solving skills.
• Excellent attention to detail and the ability to collaborate effectively across engineering and manufacturing teams.

Preferred Qualifications:

• Experience designing equipment for oil and gas, oilfield services, or industrial pumping applications.
• Familiarity with hydraulic systems and their design and implementation.
• Knowledge of API specifications, particularly API 6A, API 7K, and API 8C.
• Experience working in an ISO-certified or API Q1-certified manufacturing environment.
• Hands‑on mechanical experience, including working with mechanical systems, fabrication, or welding.
