Responsibilities include translating requirements into specs, performing critical analyses, leading design reviews, and ensuring robust, maintainable equipment through

Qualifications

• Bachelor’s degree in mechanical engineering, mechanical engineering technology, or a closely related discipline.
• At least 7 years in mechanical equipment design, machine design, equipment engineering, or manufacturing equipment development.
• At least 3 years supporting equipment after release into a production environment.
• 3D CAD and drawing capability in Creo, NX, SolidWorks, Inventor, or equivalent.
• Leadership or major contribution in multiple complex equipment failure investigations including bearings, seals, spindles, couplings, guides, actuators, pumps, valves, or fluid systems.
• Practical use of DFMEA or equipment FMEA plus at least two structured methods such as fault tree, 5 Why, fishbone, DOE, FRACAS, or Weibull analysis.
• At least 3 years in semiconductor components, wafer-fab equipment, precision optics, ceramics, aerospace, medical devices, or comparable high-precision manufacturing.
• Executed equipment verification, validation, FAT, SAT, process qualification, or reliability test plans.
• Ability to produce clear specifications, design-review packages, failure-analysis reports, and maintenance recommendations.
• Experience applying machinery risk assessment, guarding/interlock concepts, LOTO design considerations, and engineering change control.

Responsibilities

• Translate user, process, quality, safety, cleanliness, throughput, and maintenance needs into measurable equipment requirements and acceptance criteria.
• Develop concepts, trade studies, layouts, 3D CAD models, detailed drawings, bills of material, component specifications, tolerance schemes, and assembly documentation.
• Perform free-body, kinematic, tolerance-stack, thermal, structural, fatigue, vibration, fluid-flow, and pressure-drop analyses.
• Select bearings, seals, fasteners, motors, gearboxes, actuators, pumps, valves, filters, sensors, materials, coatings, and lubricants.
• Lead design reviews addressing function, weakest-link components, precision, serviceability, cleanability, and safety.
• Apply design-for-reliability, design-for-maintainability, mistake-proofing, modularity, and safe-access principles before release.
• Respond to equipment defects; diagnose root causes; review records and test data; implement corrective actions.
• Create verification plans and ensure field modifications are properly released and documented.
