Group/Division With over 40 years of semiconductor process control experience, chip makers around the globe rely on KLA to ensure that their fabs ramp next-generation devices to volume production quickly and cost-effectively. Enabling the movement towards advanced chip design, KLA's Global Products Group (GPG), which is responsible for creating all of KLA’s metrology and inspection products, is looking for the best and the brightest research scientist, software engineers, application development engineers, and senior product technology process engineers.

The RAPID division is the world leading provider of reticle inspection solutions for the semiconductor industry. The company provides inspection solutions to both the mask shops and the semiconductor fabs to ensure that lithography yields are consistently high thus enabling cost-effective manufacturing.

Job Description /Preferred Qualifications 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.

Key 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, out gassing)
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

Required Qualifications 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., Solid Works, Creo, NX)
Understanding of materials and compatibility for clean and vacuum environments

Strong problem-solving skills and ability to work in cross-functional teams

Preferred Qualifications

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)
