Requirements
- Bachelor’s or Master’s degree in Mechanical Engineering, Physics, or a related field
- 7+ years of experience in mechanical system design, with emphasis on electromechanical architectures
- Proficient with 3D CAD software (e.g., SolidWorks) for mechanical and thermal design
- Proficient with analysis and simulation tools (e.g., COMSOL, ANSYS)
- Comfortable working across disciplines in a fast-paced, R&D-driven environment
Responsibilities
- Lead the end-to-end mechanical design of the cryogenic signal chain, including wiring, filtering, cabling, and thermal anchoring from 300K to mK
- Design and optimize mechanical and thermal structures to support flex interconnects, connectors, attenuators, and other signal-path components
- Collaborate with quantum hardware and RF teams to define mechanical design strategies inside the fridge
- Conduct system-level modeling and simulation for thermal gradients, mechanical stability, and vibration mitigation
- Select and qualify materials and components for cryogenic use, with attention to thermal conductivity and mechanical performance
Preferred Qualifications
- Experience with superconducting quantum processors or similar high-precision cryogenic platforms
- Knowledge in dilution refrigerators, thermal anchoring, and multi-stage cryo hardware
- Knowledge of cryogenic interconnects, flex cables, and signal components (e.g., attenuators, filters, coax, twisted pair wires)
