Sr. Mechanical Engineer

$140,000–$160,000 annually

The Sr. Mechanical Engineer will design and develop precision mechanical components and assemblies for gas flow and process control products, including Gas Flow Controllers and Flow Ratio Controllers. This role will manage designs from concept through production while collaborating with electrical engineering, firmware, test, manufacturing, quality, and supplier teams. The engineer will support prototyping, testing, design validation, documentation, and continuous product improvement in a high-tech manufacturing environment.

• Design precision mechanical components, weldments, and assemblies for gas flow, flow ratio control, and related gas delivery products.
• Create detailed 3D models and fully dimensioned 2D production drawings using Solid Works, GD&T, and applicable drafting standards.
• Perform tolerance stack-ups, design calculations, and structural and thermal analyses, including FEA where appropriate, to verify fit, function, and reliability.
• Select materials, surface finishes, seals, and joining methods suitable for ultra-high-purity gas service and demanding process environments.
• Apply design-for-manufacturability and design-for-assembly principles when developing machined, welded, and precision-cleaned components.
• Build and test prototypes and support design verification activities, including leak, pressure, thermal, and vibration testing.
• Use test results and engineering analysis to resolve design issues and implement product improvements.
• Create and maintain bills of materials, engineering documentation, and design history records.
• Release designs and engineering change orders through PDM/PLM and ERP systems.
• Support manufacturing, quality, and suppliers with root-cause analysis and corrective action for design-related issues.
• Collaborate with cross-functional engineering teams to integrate sensors, valves, electronics, and other components into compact, serviceable assemblies.
• Ensure designs align with applicable SEMI standards, safety requirements, customer specifications, and internal quality expectations.

• Bachelor’s degree in Mechanical Engineering or a related field.
• At least 5 years of experience in mechanical engineering and mechanical design.
• Experience developing precision components, assemblies, or electromechanical products.
• Proficiency with Solid Works for 3D modeling, assemblies, and production drawings.
• Working knowledge of GD&T, tolerance analysis, design for manufacturability, and design for assembly.
• Experience with prototyping, testing, and validation of mechanical designs.
• Experience with mechanical assembly and the ability to interpret engineering drawings, specifications, and industry standards.
• Working knowledge of PDM/PLM systems and engineering change processes.
• Strong analytical, problem-solving, communication, and collaboration skills.
• Ability to work onsite and collaborate effectively with cross-functional teams.

• Experience with semiconductor capital equipment or other high-tech equipment.
• Experience with ultra-high-purity gas delivery components, mass flow controllers, valves, or fluid systems.
• Experience with FEA or CFD tools, such as Solid Works Simulation or ANSYS.
• Knowledge of gas thermodynamics and fluid dynamics.
• Familiarity with welding, precision cleaning, and leak testing of ultra-high-purity components.
• Experience with Copy Exactly! / Copy Exact! and related design replication methodologies.
• Experience working in semiconductor, industrial, or other high-tech design and manufacturing environments.
• Advanced degree in Mechanical Engineering or a related field.
