• Perform and guide detailed engineering analyses, including:
  • Structural analysis
  • Modal and vibration analysis
  • Thermal analysis
  • Fluid flow modeling
• Design and optimize systems with a focus on vibration isolation and damping performance
• Drive concept development, engineering studies, and design decisions , balancing performance, cost, and manufacturability
• Own subsystem or product-level deliverables, ensuring technical quality, schedule adherence, and accountability
• Collaborate cross-functionally with systems, manufacturing, suppliers, and service teams
• Support design reviews (RDR, CDR, DDR) , validation, and system integration
• Lead manufacturing handoff , including documentation, vendor engagement, and issue resolution during builds

Preferred Qualifications

• Experience in semiconductor capital equipment or similar high-complexity hardware systems
• Familiarity with:
  • Vibration damping and isolation techniques
  • GD&T, tolerance stack-up, and precision engineering
  • Manufacturing processes (machining, sheet metal, welding, etc.)
• Experience leading projects from concept through manufacturing release

What We're Looking For

• A self-starter who can bring structure to ambiguity
• A systems thinker who understands cross-disciplinary trade-offs
