Opto-Mechanical Engineer

CACI International•Florham Park, NJ

5d•$86,600 - $181,800

About The Position

CACI is looking for an Opto-Mechanical Engineer to join our Photonics team. 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. This role involves designing the packaging for complex subsystems with optical, photonic, optoelectronic, electrical, and mechanical elements for R&D and production programs for U.S. government customers. The engineer will own mechanical designs from concept through flight qualification, including requirements definition, trade studies, and detailed design. Collaboration with optical engineers to translate optical prescriptions into robust mechanical designs is key. The role also includes designing optical mounts and systems for launch loads, vibration, shock, thermal cycling, and vacuum environments, and developing and maintaining optical alignment strategies, including athermalization and stability over temperature. Producing build-to drawings and data packages, collaborating with and managing 3rd party vendors, and supporting integration, alignment, and test (I&T) activities are also part of the responsibilities. The role may also lead a team of other designers, analysts, and engineering professionals, and may directly supervise lab technicians.

Requirements

BS in Mechanical Engineering and a minimum of 5 years of related experience or equivalent combination of education, skills, and experience.
Proficient use of computer-aided design and analysis software, with SolidWorks and Ansys strongly preferred.
Experience working with optomechanical systems, precision structures, or high-stability mechanical assemblies.
Strong understanding of optical mounts, materials, tolerancing, and alignment techniques.
Familiarity with use of and preparation of CAD models for use in FEA software for thermal and structural (shock and vibration) analysis.
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.

Nice To Haves

Experience in the design of complex subsystems with optical, photonic, optoelectronic, electrical, and mechanical elements.
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.
Proven experience conducting mechanical simulations using ANSYS Mechanical (static, modal, thermal, nonlinear, or dynamic).
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.

Responsibilities

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.
Develop and maintain optical alignment strategies, including athermalization and stability over temperature.
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.
Support integration, alignment, and test (I&T) activities, including environmental testing and troubleshooting.
May lead a team of other designers, analysts, and engineering professionals.
May directly supervise lab technicians.
