About The Position

We are seeking a Mechanical Engineer (mid-level) to design and develop gas, water, and vacuum distribution systems for next-generation reticle inspection systems. This role focuses on fluid delivery and control architectures operating in ultra-high vacuum (UHV) environments, supporting system performance, reliability, and manufacturability. You will work cross-functionally with systems, electrical, process, and manufacturing teams to deliver robust solutions from concept through production release.

Requirements

Hands-on experience designing fluid systems (gas, liquid, or vacuum)
Familiarity with vacuum systems , including pumps, seals, leak detection, and pressure regimes
Proficiency with CAD tools (e.g., SolidWorks, Creo, NX)
Understanding of materials and compatibility for clean and vacuum environments
Strong problem-solving skills and ability to work in cross-functional teams
Bachelor's Level Degree and related work experience of 5 years

Nice To Haves

Experience with ultra-high vacuum (UHV) systems and contamination control
Knowledge of EUV systems or semiconductor process equipment
Experience with thermal management and cooling systems
Familiarity with CFD or flow simulation tools
Understanding of industry standards (e.g., SEMI, ASME B31.3 for piping where applicable)
Experience working in NPI (New Product Introduction) environments

Responsibilities

Design and develop gas, liquid cooling (water), and vacuum distribution systems for UHV semiconductor equipment
Create system architectures including piping/tubing layouts, manifolds, valves, regulators, and filtration components
Perform flow, pressure, and thermal analyses to ensure system performance and stability
Develop and release detailed CAD models, drawings, and BOMs using enterprise PLM systems
Ensure designs meet UHV compatibility requirements (materials selection, cleanliness, leak integrity, outgassing)
Conduct and support design reviews (PDR, CDR) and failure mode analysis (FMEA)
Partner with suppliers to define specifications and qualify components (valves, fittings, pumps, sensors)
Support prototype builds, integration, and system bring-up , including troubleshooting fluid/vacuum issues
Collaborate with manufacturing engineering to ensure DFM/DFA and scalable production
Drive continuous improvement for reliability, cost, and serviceability of fluid systems
