Job description

Job Summary

We are seeking an experienced Manufacturing Design Engineer for a direct hire opportunity in Houston, TX with a well-established global manufacturer serving the oil and gas equipment industry. This role is ideal for a mechanical engineering professional with direct design experience involving mud pumps, positive displacement pumps, frac pumps, or closely related high-pressure pumping equipment.

As a Manufacturing Design Engineer, you will help design, develop, and improve specialized oilfield pumping systems and mechanical equipment used in demanding applications. This position offers the opportunity to work with an experienced engineering team, collaborate closely with manufacturing and quality groups, and contribute to product improvements that impact performance, safety, reliability, and durability.

This is a strong opportunity for an engineer who enjoys hands-on mechanical design, problem-solving, and seeing products move from concept through manufacturing and testing. The work environment offers stability, supportive leadership, technical collaboration, long-term career growth, and a hybrid schedule after training.

Key Responsibilities

• Design, develop, and improve mud pumps, positive displacement pumps, frac pumps, and related oilfield mechanical equipment.
• Create 3D models, detailed engineering drawings, mechanical specifications, and design documentation.
• Perform engineering calculations, stress analysis, tolerance studies, and Finite Element Analysis to validate equipment reliability and performance.
• Evaluate mechanical components, assemblies, materials, and purchased components for high-pressure oilfield applications.
• Develop testing procedures, review performance results, and prepare technical reports with engineering recommendations.
• Collaborate with manufacturing, quality, engineering, and cross-functional teams to support product development and continuous improvement.

Compensation and Benefits

• Base salary range: $100,000 to $118,000 per year.
• Target salary range noted for this role: $110,000 to $118,000 annually.
• Annual incentive bonus opportunity: 10%, based on company profitability and performance.
• Job type: Full-time, direct hire.
• Schedule: Hybrid, with 3 days onsite and 2 days remote after successful training.
• Flexible start times with core business hours of 9:00 AM to 4:00 PM.
• Relocation assistance may be available for qualified candidates.
• Minimal travel required, including occasional domestic travel approximately once per year.
• Potential international travel to India approximately once every 2 to 3 years.
• Long-term career growth and professional development opportunities.

Required Qualifications and Skills

• Design and improve mud pumps, positive displacement pumps, frac pumps, and related mechanical equipment.
• Develop 3D CAD models, engineering drawings, mechanical specifications, and product documentation.
• Perform stress analysis, tolerance studies, FEA, and engineering calculations.
• Support design validation, testing, manufacturing collaboration, and product improvement initiatives.
• Bachelor’s Degree in Mechanical Engineering is required.
• Minimum of 3 years of mechanical engineering design experience is required.
• Direct mechanical design experience with mud pumps, positive displacement pumps, frac pumps, or closely related pumping equipment is required.
• Experience solely in maintenance, operations, or pump servicing does not meet the design requirement for this role.
• Strong mechanical and machine design background, including components, assemblies, and equipment systems.
• Proficiency with CAD software such as Creo, Autodesk Inventor, or SolidWorks.
• Experience with FEA tools such as ANSYS or SolidWorks Simulation.
• Ability to perform engineering calculations, stress analysis, tolerance studies, and design validation.
• Ability to read and interpret mechanical drawings, P&IDs, hydraulic schematics, and electrical drawings.
• Strong analytical, troubleshooting, communication, and cross-functional collaboration skills.

Preferred Qualifications

• Experience designing oilfield pumping equipment and high-pressure mechanical systems.
• Knowledge of API specifications, including API 6A, API 7K, and API 8C.
• Experience working in an ISO or API Q1-certified manufacturing environment.
• Experience with hydraulic systems and mechanical power transmission.
• Hands-on mechanical aptitude, including fabrication, welding, assembly, or equipment testing.
• Experience supporting product development from concept through manufacturing and testing.
• Master’s Degree in Mechanical Engineering.
