Mechanical Design Engineer – Process Media and Vacuum Systems (Pipe & Instrumentation Diagram)

Originally posted 21 June 2026 by the employer.

About the role

The Mechanical Design Engineer owns the system architecture for process media and vacuum systems in semiconductor equipment, encompassing gas, water, LN2, and vacuum distribution.

What you'll do

- Own the architecture for gas, water, LN2, and vacuum distribution systems while developing P&IDs, device lists, interface definitions, and requirements allocations. - Perform fluid flow and thermal simulations, alongside CAD modeling for overall routing architecture and hardware integration. - Perform hands-on mechanical design and guide support teams and contractors in CAD routing for cables, piping, tubing, and associated hardware. - Lead architecture tradeoffs and guide component selection for valves, pumps, regulators, filters, gauges, manifolds, and sensors. - Define system interfaces, interlocks, and sequencing concepts aligned with industry standards such as SEMI-S2, ASME, and PED. - Support prototype build, system bring-up, integration testing, and debugging through high-volume production release.

What you'll need

- Bachelor's degree with 8+ years of experience, Master's degree with 6+ years of experience, or Doctorate with 3+ years of experience in Mechanical Engineering or a related field. - Direct mechanical design experience with complex gas, water, cryogenic, or vacuum distribution systems. - Demonstrated background creating P&IDs, device lists, interface documentation, and system-level routing layouts. - Proficiency in fluid flow and thermal simulations. - Strong CAD skills covering routing, mechanical packaging, and hardware integration.

Nice to have

- Familiarity with Model-Based Systems Engineering (MBSE).
