Practical quantum computing. Delivered over the cloud. Backed by a16z and Alchemist.
About the role
You will lead the design of the cryogenic signal chain, define mechanical interfaces across thermal stages, and work directly alongside quantum physicists, RF engineers, and systems teams. This is a high-ownership role: you will drive design decisions end-to-end, from concept through qualification, on some of the most technically demanding hardware in the industry.

- ▸ Expert-level SolidWorks — large assemblies, GD&T-compliant drawing packages, and DFM workflows
- ▸ Independent proficiency in SolidWorks, COMSOL or ANSYS for thermal and structural analysis
- ▸ Experience with hardware operating in cryogenic, vacuum, or extreme thermal environments
- ▸ Strong ME fundamentals: stress analysis, tolerance stack-ups, materials selection, and failure mode analysis
More about this role
Rigetti Computing builds full-stack quantum computers — from superconducting qubit devices fabricated in our own foundry to cloud-accessible quantum processors. We are seeking a Senior Mechanical/Cryogenic Engineer to own the mechanical architecture of our quantum hardware systems, from room-temperature infrastructure down to the millikelvin core of our dilution refrigerators.
You will lead the design of the cryogenic signal chain, define mechanical interfaces across thermal stages, and work directly alongside quantum physicists, RF engineers, and systems teams. This is a high-ownership role: you will drive design decisions end-to-end, from concept through qualification, on some of the most technically demanding hardware in the industry.
▸ Own the mechanical design of cryogenic hardware from 300 K to millikelvin — thermal anchoring, RF wiring, flex interconnects, coaxial routing, filter housings, and connector packaging across all temperature stages.
▸ Lead the full design lifecycle: concept, CAD, GD&T drawings, BOMs, tolerance analysis, prototype builds, qualification testing, and manufacturing release.
▸ Define cryogenic mechanical interfaces and thermal conduction budgets;...
