- •Key Responsibilities: Design mechanical hardware for trapped-ion quantum computing systems, including cryogenic, UHV/XHV, and/or optical subsystems Support the design of ion-trap packages, cryogenic assemblies, vacuum-compatible structures, thermal interfaces, optical alignment features and precision optical subassemblies Develop designs that manage parasitic heat loads, thermal contraction, CTE mismatch, mechanical stability, vibration sensitivity, vacuum compatibility, and assembly tolerances.
- •Design prototype hardware and de-risk test fixtures that lab engineers can build and operate to validate new materials, interfaces, and subsystem concepts.
- •Work with optical physicists and engineers to design fiber and free-space optical systems with extremely high tolerances, mechanical stability, thermal/environmental stability, and exceptional optical performance Design complex fiber optic interconnect assemblies, connectors, routing structures, and mechanical interfaces that meet stringent optical alignment, stability, packaging, and reliability requirements.
- •Support test planning for new materials, adhesives, thermal interfaces, coatings, cryogenic assemblies, and vacuum-compatible components.
- •Work with lab engineers to evaluate outgassing, cryogenic thermal performance, mechanical stability, alignment repeatability, and failure modes.
- •Perform mechanical, thermal, and tolerance analyses to guide design decisions.
- •Generate CAD models, drawings, assemblies, interface definitions, and design documentation.
- •Partner with vacuum, cryogenic, optical, electrical, trap fabrication, and system engineering teams to identify interface risks and develop practical solutions.
- •Communicate design trades, assumptions, risks, test results, and recommendations to technical teams and program leadership.
- •You Must Have: Bachelor’s degree minimum Minimum of 5+ years (Masters and PhD inclusive) of hands-on mechanical design experience with complex hardware systems.
- •Due to Contractual requirements, must be a U.S.
