In this role, you will own the mechanical design of a precision quantum hardware subsystem that physically houses the core of our ion trap quantum computer. This subsystem integrates an ultra-high vacuum chamber, ion trap hardware, precision beam delivery and detection optics, electrical control components, and associated structural, thermal, and alignment features. The work spans early-stage architecture, detailed opto mechanical design, tolerance and stability analysis, hands on prototyping, and iteration alongside physicists, electrical engineers, and systems engineers.

Key Responsibilities:

Lead the mechanical development and deployment of precision, multi-functional, quantum hardware assemblies from early concepts to detailed design to final procurement for next-generation trapped-ion quantum computers.

Design mechanical interfaces, mounting structures, and housing modules for complex optical, electrical, cryogenic, and vacuum subsystems.

Design precision environmental control systems.

Work with subsystem leads and systems engineers to maintain thorough interface control documents (ICDs).

Derive detailed mechanical subsystem and component requirements from higher-level requirements.

Maintain thorough, version-controlled CAD models and BOMs.

Partner with lab validation & integration teams to build and test proto@type assemblies.

Complete FEM models to predict the structural, electrical, thermal, magnetic, and acoustic performance of complex subsystem assemblies.

Partners with quantum physicists and subsystem leads to optimize optical, electrical, cryogenic, and vacuum subsystem designs.

Partner with manufacturing team leads to optimize the lead time, SWAP-C, and uptime of subsystems.

Communicate findings and design proposals to larger technical, management, and executive teams.

Mentor junior engineers.
