Job Summary

The Principal Optomechanical Analyst will be a technical expert in optomechanical modeling and analysis who will serve as a resource for the entire TMT partnership.  This position is in the Optics Group, which is part of the TMT Telescope Department; however, the person in this position will at times be called upon to review work being done for several TMT project groups in each of the partner countries.

The primary work location will be at the TMT Project office in Pasadena, CA, but frequent travel to the TMT partner countries will be required.

Job Duties and Responsibilities

  • Review the finite-element modeling performed by contractors and partner institutions in the design of optical subsystems, science instruments adaptive optics systems, etc.
  • Provide expert advice and mentoring when necessary, to improve the modeling techniques of the subsystem teams.
  • Participate as a reviewer in subsystem design reviews.
  • Develop, analyze and optimize structural designs of large mirror handling equipment.
  • Perform thermal-structural analyses on the main telescope structure.
  • Perform tolerance studies and trade studies.
  • Help prepare specifications and other procurement documents for the optical subsystems.
  • Prepare and deliver technical presentations.
  • ‚ÄčWrite technical reports and papers.

Minimum Requirements

  • An advanced degree in mechanical engineering, engineering mechanics or equivalent.
  • 10 years experience in optomechanical engineering analysis.
  • The project office is located in Pasadena and residence in the area is required.
  • Frequent international travel (approximately 15% of the time) to visit suppliers in China, India and Japan will be necessary in order to fulfill the duties of this position.

Required Technical Knowledge, Skills and Abilities

  • Expert knowledge of the use of finite-element analysis for optomechanical engineering, particularly optical surface analysis, the design and optimization of large mirror supports and active optics systems.
  • Strong background in geometric optics.
  • Knowledge of structural mechanics and engineering materials.
  • Familiarity with optical ray tracing programs, e.g., CodeV and Zemax, for performing tolerance and sensitivity studies.
  • Understanding of orthogonal polynomials used to evaluate mirror flexure, including Zernike polynomials, natural bending modes (eigenvectors) and SVD modes.
  • Understanding of kinematic principles.
  • Expertise in steel structure design, particularly the design of large telescope structures.
  • Experienced in the design of whiffletree supports and optical handling equipment.
  • Experienced user of Ansys or Nastran with good Matlab programming skills.

Required Personal Skills

  • Excellent organizational skills.
  • Good interpersonal team-building skills.
  • Good English communication skills.
  • Ability to write clear and concise technical reports and papers.
  • Ability to work on multiple tasks in parallel.
  • Experience in mentoring younger engineers or engineering graduate students.
  • Must be able to perform work to meet schedules.

Experience and skills that would also be valuable

  • Knowledge of large optics fabrication and testing techniques.
  • Experience with large optical telescopes.
  • Knowledge of adaptive optical systems.
  • Experience in all phases of a major project, including design, fabrication, integration and testing.
  • Fluency with Japanese, Chinese, or Hindi language.
