Group/Division

With over 40 years of semiconductor process control experience, chipmakers 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 systemsfor UHV semiconductor equipment

• Create system architectures including piping/tubing layouts, manifolds, valves, regulators, and filtration components

• Perform flow, pressure, and thermal analysesto ensure system performance and stability

• Develop and release detailed CAD models, drawings, and BOMsusing 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/DFAand scalable production

• Drive continuous improvementfor reliability, cost, and serviceability of fluid systems

Preferred Qualifications

• Experience with ultra-high vacuum (UHV)systems and contamination control

• Knowledge of EUV systemsor 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

Key Competencies

• Systems thinking and ability to work across disciplines

• Attention to detail in high-precision environments

• Strong communication and technical documentation skills

• Ownership mindset from concept through release

What You'll Work On

• High-performance vacuum and gas delivery architecturesenabling EUV inspection

• Precision cooling systemsfor thermal stability at nanometer-level accuracy

• Complex integration challenges where mechanical, fluid, and vacuum systems intersect

Minimum Qualifications

Bachelor's Level Degree and related work experience of 5 years
