CACI is looking for a Mechanical Engineering Analyst to join our photonics team-- we are expanding!  Our laser communications technology is helping NASA provide high-definition video from the International Space Station, and to explore asteroids 250 million miles away.  Our other optical technology can also help scientists discover biohazards; support intelligence, surveillance, and reconnaissance missions; and protect soldiers from explosive devices.  Do you have a passion for innovation?  Apply now and join the team!

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.
• Develop, run, and validate finite element analysis (FEA) models using ANSYS Mechanical and related simulation tools.
• Perform and interpret static, thermal, modal, random vibration, shock, and thermal distortion analyses aligned with spacecraft environmental requirements.
• Interpret simulation results and provide actionable recommendations to design, manufacturing, and project teams.
• Support optical performance sensitivity studies, linking mechanical deformation and thermal gradients to impacts on optical alignment and wavefront error.
• Collaborate with hardware designers to jointly optimize circuit card layout with special attention to thermal performance and mitigation.
• 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.
• May lead a team of other designers, analysts, and engineering professionals

Qualifications:

Required: 

• BS in Mechanical Engineering and a minimum of 7 years of related experience or equivalent combination of education, skills, and experience.
• Proficient use of computer-aided design and analysis software, with SolidWorks strongly preferred.
• Proven experience conducting mechanical simulations using ANSYS Mechanical (static, modal, thermal, nonlinear, or dynamic).
• Strong understanding of engineering fundamentals, including mechanics of materials, heat transfer, vibration, and structural dynamics.
• Experience in the design of complex subsystems with optical, photonic, optoelectronic, electrical, and mechanical elements.
• Familiarity with Design for Manufacturing (DFM) and Design Failure Mode and Effects Analysis (DFMEA) methodologies, with experience applying these principles to improve product quality and manufacturability.
• Must be a US Citizen.

Desired:

• Experience working with optomechanical systems, precision structures, or high-stability mechanical assemblies.
• Experience with gimbal systems or other precision motion control mechanisms, including design, integration, and optimization for applications in optical systems or robotics.
• Familiarity with material behavior in space environments, such as CTE matching, thermal gradients, and outgassing considerations.
• Experience in environmental testing to MIL-STD or equivalent industrial test levels, including shock, vibration, thermal, and EMI/EMC.
• Experience in optical and electronic subassembly layout including board physical design, chassis or enclosure design, optical fiber routing, and electrical and optical connector selection.
• Master’s degree preferred
