Staff Mechanical Engineer
$115,200–$172,800 year
On-siteBudd Lake, New Jersey, United States
Job Summary
Op-to-Mechanical design and development of precision optical-mechanical assemblies for next-generation semiconductor metrology equipment. Lead design activities to ensure optical alignment stability under thermal and vibrational variations; perform tolerance analyses and error budgeting; integrate lasers, detectors, imaging, and illumination paths; prototype, test, and validate subsystems; collaborate with manufacturing for production transfer; contribute to system-level design reviews and continuous improvement. Strong emphasis on precision mechanics, optical alignment, environmental stability, and cross-functional teamwork in a semiconductor metrology context.
Required Qualifications
- Bachelor’s or Master’s degree in Mechanical Engineering, Optical Engineering, or related field.
- 7+ years of experience in opto-mechanical design, preferably in semiconductor, photonics, or precision instrumentation.
- Strong understanding of optical systems, including imaging, laser systems, interferometry, or illumination design.
- Proficiency with CAD tools (e.g., SolidWorks, Creo, NX).
- Experience with FEA tools (e.g., ANSYS, COMSOL) for thermal and structural analysis.
- Knowledge of precision manufacturing methods (CNC machining, EDM, additive, etc.).
- Familiarity with GD&T and tolerance stack-ups.
Desired Qualifications
- Experience with semiconductor metrology or inspection equipment (e.g., scatterometry, CD-SEM, overlay metrology).
- Understanding of vibration isolation, air-bearing stages, and ultra-stable structures.
- Experience integrating optical components such as lenses, mirrors, beam splitters, and fiber systems.
