• Provide hands-on engineering support during prototype assembly, subsystem integration, testing, and production introduction to verify the design and resolve hardware issues.
• Investigate vacuum, mechanical, contamination, and reliability issues using data-driven root cause analysis; implement and validate corrective design actions.
• Participate in design reviews, technical risk assessments, FMEA/FMECA activities, and Design for Excellence reviews, including DFM, DFA, DFS, and DFR.
• Collaborate with Systems, Optics, Stage, Source, Manufacturing, Quality, Service, Integration, and Facilities teams to manage mechanical interfaces and ensure subsystem compatibility.
• Work directly with suppliers on technical requirements, design reviews, prototype fabrication, process capability, nonconformance resolution, and qualification of mechanical components and assemblies.
• Prepare and release engineering documentation, including assembly and test procedures, technical reports, design-review materials, and engineering change orders.
• Address product issues throughout development, integration, production, and field-support phases while maintaining technical ownership of assigned hardware.

Preferred Qualifications

• Demonstrated experience designing complex mechanical systems, precision assemblies, or vacuum equipment.
• Knowledge of vacuum-system design principles, vacuum-compatible materials, sealing technologies, leak testing, and contamination control.
• Proficiency with a 3D CAD platform such as Creo, NX, SolidWorks, or equivalent.
• Strong understanding of GD&T, tolerance analysis, mechanical drawings, materials selection, fastening methods, and manufacturing processes.
• Experience with structural, thermal, or vibration analysis and the ability to interpret analysis and test results.
• Experience developing prototypes and executing design verification or qualification testing.
• Working knowledge of DFM, DFA, DFS, DFR, FMEA/FMECA, RCCA, or 8D methods.
• Ability to independently execute moderately complex engineering assignments, communicate technical decisions, and drive issues to closure.
• Experience working with suppliers on custom mechanical parts and assemblies.
• Experience in semiconductor capital equipment, precision instrumentation, vacuum equipment, aerospace, medical devices, or another highly regulated/high-technology industry is preferred.

Minimum Qualifications Master's Level Degree and related work experience of 3 years; Bachelor's Level Degree and related work experience of 5 years
