The Opportunity:

The Optical and Photonics Systems group of CACI is looking for candidates to help develop the next generation of optical technologies.  These include free-space optical communications terminals and modems and high-power optical sources across the optical spectrum.  Particularly, efforts will develop the next generation of capabilities, with previous successes having flown on the International Space Station as part of an optical communications relay demonstration and another having achieved the current largest data optical transmission range of >19 million miles, along with developing the Space Defense Agency’s standard terminal for laser communications.

This position is contingent upon contract award.

Responsibilities:

  • Support the design and architecture of the mechanical subsystems for free-space optical communications terminals, modems, and high-power optical sources

  • Create detailed CAD models of mechanical components and assemblies using software like SolidWorks or similar

  • Perform Finite Element Analysis (FEA) and hand calculations to evaluate the structural integrity of mechanical systems under various loading conditions

  • Create presentations to document and communicate design, analysis, test results, and performance metrics to stakeholders

  • Work closely with other disciplines to ensure mechanical systems meet overall system requirements

  • Develop prototypes and conduct testing to validate mechanical system performance

  • Collaborate with hardware designers to jointly optimize circuit card layout

  • Produce build-to drawings and data packages and collaborate with and manage 3rd party vendors to resolve specification, performance, and reliability issues and realize the commercial and custom-machined parts necessary to build the subsystem

  • Develop assembly processes and write build procedures

Qualifications:

Required:

  • US citizenship required

  • Bachelor’s degree in Mechanical Engineering, or similar field, or equivalent combination of education, skills, and experience

  • Proficient use of computer-aided design and analysis software, with SolidWorks strongly preferred.

  • Ability and willingness to jump in and learn

  • Able to design in assemblies with larger number of parts and interfaces

  • Experience with Geometric Dimensioning and Tolerancing (GD&T)

  • Hands-on mindset, able to transition between CAD/analysis and real hardware

Desired:

  • Working knowledge of finite element analysis

  • Experience in the design of complex subsystems with photonic, optoelectronic, electrical, and mechanical elements.

  • Experience in electronic subassembly layout including board physical design, chassis or enclosure design, optical fiber routing, and electrical and optical connector selection.

This position is contingent on funding and may not be filled immediately. However, this position is representative of positions within CACI that are consistently available. Individuals who apply may also be considered for other positions at CACI.
