Job summary

Pivotal Systems in Reno, NV or Fremont, CA is seeking a Mechanical Design Engineer to design precision mechanical components for gas flow controllers and related products, from concept through production.

You will create 3D models in SolidWorks, perform tolerancing and validation tests, and collaborate with electrical, firmware, and quality teams on-site to deliver robust, manufacturable solutions.

Qualifications

• Bachelor’s degree in Mechanical Engineering or related field.
• 3+ years of mechanical design experience developing precision components or electromechanical products.
• Proficiency in SolidWorks for 3D modeling and drawings; experience with PDM/PLM.
• Knowledge of GD&T and tolerance analysis.
• Experience with prototyping, testing, and validation.
• Ability to interpret drawings and standards.
• On-site collaboration with cross-functional teams.
• Experience in gas delivery or high-purity systems is a plus.

Responsibilities

• Design precision mechanical components, weldments, and assemblies for gas flow controllers, flow ratio controllers, and related gas delivery products, from initial concept through release to production.
• Create detailed 3D models and fully dimensioned 2D drawings in SolidWorks, applying GD&T and company drafting standards.
• Perform tolerance stack-ups, design calculations, and structural and thermal analyses to verify fit, function, and reliability.
• Design for UHP gas service: select materials, surface finishes, seals, and joining methods compatible with high-purity, corrosive, and reactive process gases.
• Apply design-for-manufacturability and design-for-assembly (DFM/DFA) principles, working with machining, welding, and precision-cleaning suppliers to ensure parts are manufacturable, inspectable, and cost-effective.
• Build and test prototypes; plan and run design verification tests such as leak, pressure, thermal, and vibration testing, and use results to drive design improvements.
• Create and maintain bills of materials (BOMs), release designs and engineering change orders (ECOs) through PLM/ERP systems, and maintain design history documentation.
• Support manufacturing, quality, and suppliers with root-cause analysis and corrective action on design-related issues using tools such as 8D and FMEA.
• Ensure designs comply with applicable SEMI standards, safety requirements, and customer specifications.
• Collaborate with electrical, firmware, and test engineers to integrate sensors, valves, and electronics into compact, serviceable assemblies.
