Mechanical Engineer (gas/water/vacuum systems)

KLA is a global leader in diversified electronics for the semiconductor manufacturing ecosystem. Virtually every electronic device in the world is produced using our technologies. We invent systems and solutions for the manufacturing of wafers and reticles, integrated circuits, packaging, printed circuit boards, and flat panel displays. Our expert teams of physicists, engineers, data scientists, and problem-solvers work together with the world’s leading technology providers to accelerate the delivery of tomorrow’s electronic devices.

About the Role

The Global Products Group (GPG) at KLA, responsible for creating all of KLA’s metrology and inspection products, is seeking a mid-level Mechanical Engineer 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 collaborate cross-functionally with systems, electrical, process, and manufacturing teams to deliver robust solutions from concept through production release.

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

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

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)
• 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 architectures enabling EUV inspection
• Precision cooling systems for thermal stability at nanometer-level accuracy
• Complex integration challenges where mechanical, fluid, and vacuum systems intersect

Qualifications

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

Pay

Base pay range: $117,800.00 - $200,300.00 annually.

Benefits

• Performance incentive programs
• Medical, dental, vision, life, and other voluntary benefits
• 401(K) with company matching
• Employee stock purchase program (ESPP)
• Student debt assistance and tuition reimbursement program
• Development and career growth opportunities and programs
• Financial planning benefits
• Wellness benefits including an employee assistance program (EAP)
• Paid time off and paid company holidays
• Family care and bonding leave

Interns are eligible for some of the benefits listed.
