Job Description: 

Seeking a Senior Optical Metrology Engineer. 

SAO’ s development of active mirrors for X-ray imaging involves fabricating thin-shell glass mirrors that have active elements lithographically printed on the back of the mirror.

By applying a voltage to the mirror’ s actuators, we change the optical figure of the mirror, thus allowing optical correction in real time. In support of this research and development, we need an optical metrology engineer to measure the mirrors throughout the fabrication and mounting process.

Other tasks include operating mirror control electronics, as well as measuring the actuator’ s influence functions and using that information to model (and optimize) the mirror’ s performance.

Required Skills:

·          Must be a U.S. Citizen or permanent resident.

·          Minimum MS in Optical Engineering, or Physics with an emphasis on Optical metrology (candidates with BS in optical engineering or optical physics with at least 5 years’ experience in optical metrology will be considered)

·          Experience with diverse optical metrology setups: Interferometers, Shack – Hartmann sensor, and optical alignment.

·          Experience in optical design/analysis software like: CodeV and/or Zemax, MATLAB, Python

·          Competency in optical design theory, lasers, polarization, detectors, electro-optical devices and opto-mechanical constructions

·          Strong written and oral communicative skills and a commitment to achieving results on time

·          Demonstrated “ team player”

·          Ability to interface with multidisciplinary groups, work effectively in a team and willingness to take on responsibility, follow through and keep multiple simultaneous assignments on schedule

·          Ability to quickly acquire technical knowledge from documentation and on-the-job training thoroughly investigating technical issues (analytically and hands-on in a lab).

Desired Skills: 

·          Working independently, develop and operate optical test equipment and test stations involving interferometers, Shack-Hartmann based wavefront sensors, and associated positioning apparatus.

·          Understand and operate the control electronics that drive our mirrors.

·          Develop and improve the modeling algorithm we use to optimize the mirror based on empirically derived actuator influence functions.

·          Decompose top-level system requirements into lower level module, sub-module, or component level design specifications for product or test equipment;

·          Develop alignment methods for complex optical sensors and systems. Develop tooling and test equipment to support optical sensor alignment methods;

·          Develop clear understanding of optical tests needed for qualifying optical sub-modules.

·          Prepare leading system engineer documentation (Element Performance Specifications, Element Design Specifications, Test Performance Specification; Test Analysis Reports) through review, release and change control;

·          Support preparation of design reviews for the development team;

·          Write engineering procedures and train technicians to efficiently transfer build, alignment, and test processes.

·          Clearly communicate progress and status of ongoing technical activities to management
