Mechanical Design Engineer; vacuum system

Our inspection, metrology, and analytics systems detect and monitor defects across logic and memory chips, specialty semiconductors, wafers, reticles, advanced packaging, process equipment and materials. We also develop technologies for specialty processes, IC substrates, and PCB manufacturing, including etch and deposition, component inspection, and imaging and analytics. The RAPID division leads the industry in reticle inspection solutions, helping ensure high lithography yields and cost-effective semiconductor manufacturing.

Its systems support both mask shops and fabs by detecting defects early in the process, enabling faster, more reliable production.

In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.

• Lead the mechanical design, integration, and validation of complex, multi‑chamber subsystems, ensuring structural stability, precision performance, and robust contamination control.
• Design and develop ultra‑clean vacuum system hardware, including chamber structures, interfaces, materials/finishes, seals, and internal components, applying UCV principles such as low‑out gassing materials, precision cleaning requirements, and contamination‑minimizing geometries.
• Develop mechanical concepts and detailed designs for chambers, frames, interfaces, mounts, enclosures, and precision mechanisms; create drawings, specifications, and requirements for cross‑functional teams.
• Drive structural, thermal, fluid, and vibrational analyses to optimize component performance and system stability.
• Collaborate closely with optics, metrology, electrical, controls/PLC, software, manufacturing, and service teams to ensure subsystem compatibility and seamless system‑level integration.
• Support vacuum‑related elements across chambers (e.g., main chamber, stage chamber, transfer chamber, etc.) by defining interfaces, mechanical constraints, and performance requirements that integrate with overall system design.
• Contribute to the development and documentation of vacuum operation schemes (pump‑down, roughing, purge, vent, bake/clean cycles), and partner with Controls/SE on interlocks and sequencing.
• Establish and maintain contamination‑control strategies—including materials selection, cleanliness/handling guidelines, and UCV‑grade component practices—working with Materials Engineering and Supply Chain to evaluate suppliers.
• Perform first‑order and detailed analyses for pumping configurations, conductance effects, and subsystem‑level performance impacts; collaborate with vacuum specialists as needed for deeper modeling.
• Lead mechanical and system‑level design reviews (CDR, DDR), ensuring design requirements flow correctly to partner teams (mechanical, electrical, opto‑mechanical, metrology, EFEM/loader, source).
• Own integration of chambers and platform structures for vibration isolation, optical stability, and stage dynamic performance.
• Plan, execute, and oversee test activities—prototype chambers, subsystem test stands, and pre‑factory builds—including instrumentation, test methods, data analysis, and acceptance metrics.
• Manage risk through FMEA, issue tracking, corrective actions, and design‑for‑reliability improvements across NPI and into HVM.
• Mentor engineers, establish best practices (DfX, contamination handling, documentation standards), and maintain engineering artifacts and decision rationale for long‑term R&D continuity.
