Job description

Compensation:

$110,000-$130,000 annual salary

Position Summary:

The Jr. 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 position will contribute to projects from initial concept through production release, creating detailed designs, supporting prototype builds and testing, and partnering with cross-functional teams to deliver reliable, manufacturable products. This is an excellent opportunity to expand mechanical design expertise while gaining hands‑on experience across product development, validation, manufacturing, and continuous improvement.

Key Responsibilities:

• Design precision mechanical components, weldments, and assemblies from concept through production release.


• Create detailed 3D models and fully dimensioned 2D drawings using SolidWorks, applying GD&T and company drafting standards.


• Perform tolerance stack‑ups, design calculations, and structural and thermal analyses, including FEA when appropriate.


• Select materials, surface finishes, seals, and joining methods suitable for high‑purity, corrosive, and reactive process gases.


• Apply design‑for‑manufacturability and design‑for‑assembly principles to ensure components are manufacturable, inspectable, reliable, and cost‑effective.


• Collaborate with machining, welding, and precision‑cleaning suppliers to support production requirements.


• Build and test prototypes and support design verification activities, including leak, pressure, thermal, and vibration testing.


• Analyze test results and implement design improvements to enhance product performance and reliability.


• 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 actions for design‑related issues.


• Collaborate with electrical, firmware, test, manufacturing, and quality teams to integrate sensors, valves, and electronics into compact, serviceable assemblies.


• Ensure designs align with applicable SEMI standards, safety requirements, customer specifications, and internal quality expectations.

Required Qualifications:

• Bachelor’s degree in Mechanical Engineering or a related field.


• At least 3 years of mechanical design experience developing precision components or electromechanical products.


• Proficiency with SolidWorks for 3D modeling, assemblies, and production drawings.


• Working knowledge of PDM/PLM systems, GD&T, tolerance analysis, and design‑for‑manufacturability principles.


• Experience with mechanical prototyping, testing, and design validation.


• Ability to interpret engineering drawings, technical specifications, and industry standards.


• Strong analytical, problem‑solving, and organizational skills with close attention to detail.


• Effective communication and collaboration skills in a cross‑functional, onsite work environment.

Preferred Skills & Experience:

• Five or more years of mechanical design experience in precision components, electromechanical products, semiconductor equipment, or other high‑tech equipment.


• Experience with UHP gas delivery components, mass flow controllers, valves, or other fluid systems.


• Experience with FEA or CFD tools, such as SolidWorks Simulation or ANSYS.


• Knowledge of gas thermodynamics and fluid dynamics.


• Familiarity with welding, precision cleaning, and leak testing of UHP 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.
