Senior Opto-Mechanical Engineer

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. 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 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. Desired: 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.
