Senior Mechanical Design Engineer (Semiconductor)

Location: Milpitas, California, United States

Salary: $141,300–$207,233 annually

Company

hirify.global develops inspection tools, metrology systems, process solutions, and computational analytics for semiconductor manufacturing, including systems for logic and memory chips, wafers, reticles, advanced packaging, and process equipment.

What you will do

• Design, develop, and maintain next-generation multi-degree-of-freedom ultra-precision motion stages for high-vacuum eBeam inspection and review platforms.
• Take mechanical designs from requirements and concept through detailed design, prototyping, validation, qualification, and sustaining.
• Develop stage structures, flexures, precision mechanisms, vacuum-compatible materials and hardware, bearings, guides, actuators, metrology interfaces, thermal management, and vibration-isolation solutions.
• Create parts and assemblies in Creo or SolidWorks, produce detailed drawings with GD&T, and maintain design-review and release discipline.
• Perform structural, thermal, vibration/modal FEA and tolerance stack-up analysis; build, test, troubleshoot, and correlate prototype models with modal-test data.
• Partner with controls, systems, manufacturing, and suppliers to improve performance, manufacturability, reliability, serviceability, and precision-part quality; develop safety features and production or service tooling.

Requirements

• Mechanical Engineering or related degree, with experience in motion systems, precision mechanics, or mechatronics.
• Several years of work experience using Creo, SolidWorks, or a similar 3D CAD modeling tool, together with structural, thermal, and vibration/modal FEA.
• Design-for-manufacturing experience across machining, sheet metal, and castings.
• Working knowledge of data-analysis tools such as Python or MATLAB.
• Minimum related experience: 3 years with a doctorate, 6 years with a master's degree, or 8 years with a bachelor's degree.

Nice to have

• Experience with feedback systems using laser interferometers, high-resolution optical encoders, linear motors, linear guides, air bearings, and similar components.
• Experience designing dynamic X-Y sub-micron positioning stages, including vibration and modal testing with accelerometers, impact hammers, and comparable instrumentation.
• Semiconductor capital-equipment design experience.

Culture & Benefits

• Full-time employment in a central engineering organization with collaboration across controls, systems, manufacturing, and supplier teams.
• Medical, dental, vision, life, and other voluntary benefits.
• 401(k) with company matching, employee stock purchase program, student debt assistance, and tuition reimbursement.
• Paid time off, company holidays, family care and bonding leave, wellness benefits, financial planning, and employee assistance programs.
• Development and career growth opportunities.

Hiring process

• Interviews evaluate individual skills, problem-solving approach, and authentic thinking.
• Use of AI or recording tools during interviews is not permitted unless explicitly approved as a reasonable accommodation or invited by the interviewer.
