Optomechanical Engineer

Job Title

Optomechanical Engineer

Role Summary

Member of the CTO Optical Development group responsible for developing next-generation optomechanical systems for semiconductor process control. Focus on designing high‑precision, stable optical assemblies across wavelengths from EUV to NIR under cleanroom and vacuum constraints.

Experience Level

Mid-level. The role typically requires at least 5 years of experience in high-precision optical system development.

Responsibilities

Design, analyze, prototype and validate precision optomechanical systems and their integration into optical instruments.

• Design and develop optomechanical architectures across EUV, VUV, DUV, VIS, and NIR systems.
• Define optical mounting, alignment strategies, and system error budgets.
• Perform thermal and structural analyses using FEM tools.
• Conduct vibration analyses (modal, PSD, harmonic response) to ensure system stability.
• Execute CFD simulations for airflow and thermal management designs.
• Select materials and define bonding/cementing approaches for long-term stability.
• Ensure compliance with cleanliness, photocontamination, stray light, vacuum, and cleanroom requirements.
• Drive prototyping, system integration, experimental validation, and supplier collaboration.
• Define and implement optical alignment concepts and tooling (e.g., autocollimators, wavefront sensors).
• Collaborate with cross-functional engineering teams and external suppliers.

Requirements

Core technical and hands-on capabilities required to perform the role.

• Must-have:
  • Minimum 5 years experience in high-precision optical system development.
  • Experience with high-NA optical systems; EUV/DUV/VUV experience preferred.
  • Proficiency in CAD and simulation tools (e.g., ANSYS Mechanical, CREO, SolidWorks, FEM platforms).
  • Strong understanding of thermal, structural, and material behavior in precision systems.
  • Experience with vibration analysis (modal, PSD, harmonic response) and CFD simulations.
  • Proven track record in prototyping, supplier collaboration, and system realization.
  • Strong analytical and problem-solving skills and system-level thinking.
• Nice-to-have:
  • Experience working with vacuum and high-cleanliness environments.
  • Familiarity with advanced manufacturing and precision engineering techniques.

Education Requirements

MSc or PhD in Mechanical Engineering, Optomechanical Engineering, or a closely related technical field.
