Mechanical Design Engineer – Process Media and Vacuum Systems

About the role

KLA, a semiconductor equipment company, is hiring a Mechanical Design Engineer in Milpitas to own the system architecture for process media and vacuum systems in advanced semiconductor equipment, including gas, water, LN2 and vacuum distribution. The engineer develops and maintains system documentation such as P&IDs, device lists and interface definitions, works across mechanical, electrical, software, manufacturing, service and reliability teams, performs CAD work for routing architecture and guides contractors in piping and tubing routing. Familiarity with Model-Based Systems Engineering (MBSE) is a plus.

Key responsibilities

• Own the architecture for gas, water, LN2 and vacuum distribution systems.
• Develop and maintain P&IDs, device lists, interface definitions and requirements allocations.
• Perform fluid flow and thermal simulations.
• Create CAD models and layouts for routing architecture and hardware integration.
• Perform hands-on mechanical design and guide support teams in CAD routing of cables, piping and associated hardware.
• Lead architecture tradeoffs and guide selection of valves, pumps, regulators, filters, gauges, manifolds and sensors.
• Define system requirements and allocate them to subsystems and technical owners across functions.
• Help define interfaces, interlocks and sequencing concepts (SEMI-S2, ASME, PED).
• Support system integration, design reviews, troubleshooting, productization and full documentation for high-volume production.
• Support prototype build, system bring-up, testing and debugging of routing and integration issues.
• Interface with vendors and internal stakeholders and prepare content for design reviews.

Required profile

• Degree in Mechanical Engineering or a related field.
• Experience with complex gas, water, cryogenic and/or vacuum distribution systems.
• Experience with P&IDs, device lists, interface documentation and system-level routing layouts.
• Experience in multidisciplinary engineering teams and supporting prototype build, integration and troubleshooting.
• Minimum qualifications: doctorate with 3 years of related experience, master's with 6 years, or bachelor's with 8 years.

Required skills

• Fluid flow and thermal simulation
• Mechanical design and CAD, including routing and integration
• P&ID and interface documentation
