Mechanical Design Engineer (Vacuum System)

Location: Milpitas, California, USA; onsite

Salary: $117,800–$172,800 annually

Company

hirify.global develops semiconductor inspection tools, metrology systems, process solutions, and computational analytics for chip and electronics manufacturing.

What you will do

• Lead the mechanical design, integration, and validation of complex multi-chamber subsystems, including ultra-clean vacuum chambers, frames, interfaces, mounts, enclosures, seals, and precision mechanisms.
• Develop drawings, specifications, requirements, vacuum operation schemes, and contamination-control strategies for system-level integration.
• Perform structural, thermal, fluid, vibrational, pumping, conductance, and subsystem-performance analyses.
• Collaborate with optics, metrology, electrical, controls/PLC, software, manufacturing, service, Materials Engineering, and Supply Chain teams.
• Lead design reviews, integrate chambers and platform structures for vibration isolation and optical stability, and manage requirements across partner teams.
• Plan and oversee prototype, subsystem, and pre-factory testing, including instrumentation, data analysis, acceptance metrics, FMEA, issue resolution, and reliability improvements through NPI and HVM.

Requirements

• MS or PhD in Mechanical Engineering or a related field such as Applied Physics, Materials Science, or Electrical Engineering.
• 8–12+ years of experience in mechanical design and integration of complex systems, including semiconductor equipment, precision instrumentation, multi-chamber tools, or equivalent.
• Strong foundation in precision mechanical design, structural/thermal/vibration analysis, contamination control, materials and finishes, and system-level integration.
• Familiarity with vacuum principles including pumping, conductance, gauging, and cleanliness.
• Proficiency in 3D CAD/PLM workflows and analysis tools such as ANSYS, COMSOL, or similar.
• Experience with Python or Matlab for data processing and modeling, and collaboration with PLC/HMI teams.
• Cross-functional leadership, clear technical communication, supplier interaction, issue-resolution ownership, and mentoring experience.
• Experience with vacuum operation schemes and PLC-controlled interlocks is a plus but is not required as the primary role.
• Minimum education or equivalent experience: doctorate or 2 years of work experience, master's degree or 4 years of work experience, or bachelor's degree or 5 years of work experience.
