More About the Role:
You will assist with the packaging and integration of optical systems based around telescopes, gimbals, custom and COTS PCBs, passive, active, and free space components, and their supporting hardware. These systems are frequently integrated onto a variety of host platforms including satellites and aircraft, which requires design, analysis, simulation, and field measurements to ensure peak performance.


The Opportunity:

  • Under limited direction design the packaging for complex subsystems with optical, photonic, optoelectronic, electrical, and mechanical elements for R&D and production programs for U.S. government customers.
  • Own mechanical designs from concept through flight qualification, including requirements definition, trade studies, and detailed design.
  • Collaborate with optical engineers to translate optical prescriptions into robust mechanical designs.
  • Design optical mounts and systems for launch loads, vibration, shock, thermal cycling, and vacuum environments.
  • Collaborate with and manage 3rd party vendors to resolve specification, performance, and reliability issues to realize the commercial and custom parts necessary to build the system.
  • Support integration, alignment, and test (I&T) activities, including environmental testing and troubleshooting
