Job Posting: Optomechanical Engineering Technologist 


Job Number: 1903549 
University of Toronto
Faculty/Division: Faculty of Arts and Science 

Department: Dunlap Institute for Astronomy and Astrophysics 
Campus: St. George (downtown)



Under the direction of the Project Leader of the Gemini Infrared Multi-Object Spectrograph (GIRMOS), this position is responsible for the design, analysis, integration and testing of precision, cryogenic optical mounts and mechanisms for the GIRMOS. GIRMOS is a major scientific nationwide project funded by the Canada Foundation for Innovation (CFI) and provincial authorities to provide a state-of-the-art scientific capability to the Gemini Observatory located in Chile by taking advantage of latest developments in adaptive optics and infrared spectroscopy. The successful candidate should be comfortable designing opto-mechanical components (lens, mirror and prism mounts) as well as motorized mechanisms for use in vacuum environments and at cryogenic temperatures (80 Kelvin).

Your responsibilities will include:

  • Designing, modifying and fabricating custom machine parts
  • Performing design processes that require great precision and attention to many details
  • Advising on suitability of experimental apparatus and fabrication techniques
  • Performing complex or scientific diagnostic tests
  • Determining technical requirements for fabrication projects
  • Creating and reviewing technical drawing sets for manufacturing
  • Designing, modifying and fabricating custom lab apparatus, tools and jigs
  • Serving as a resource on specific issues to a group of specialists

 Essential Qualifications:

    • Bachelor Degree in Engineering or acceptable combination of equivalent experience
    • Minimum six years design experience in precision optomechanics
    • Demonstrated ability to design opto-mechanical components using SolidWorks, or other similar Computer Aided Design software
    • Demonstrated ability to perform thermal and structural analysis using ANSYS, or other similar Finite Element Analysis software
    • Prior experience with design and analysis of opto-mechanical components (lens and mirror mounts, imaging detector mounts, structures, and mechanisms) for use at temperatures below 100 Kelvin
    • Ability to work alongside other Mechanical and Optical Engineers, to assist with design, integration, alignment and test of numerous opto-mechanical assemblies into the GIRMOS instrument.

Assets (Non-Essential):

  • Previous experience assembling precision opto-mechanical components and testing them at cryogenic temperatures
  • Previous experience assisting with the alignment of optical systems, using tools such as auto-collimators, alignment telescopes and coordinate measuring machines
  • Previous experience operating cryogenic test facilities, including vacuum chambers, pumps, gauges, cryogenic coolers and temperature monitoring systems
  • Strong understanding of mechanical and thermal material behaviour at low temperatures
  • Strong understanding of kinematic design principles
  • Ability to use Zemax optical design software and carry out optomechanical tolerancing

To be successful in this role you will be:

  • Efficient
  • Meticulous
  • Multi-tasker
  • Proactive
  • Problem solver
  • Resourceful
