Job description

Senior Mechanical Engineer - Cryogenic at Rigetti Computing, Berkeley, CA. A senior-level full time position in the Hardware Engineering team, listed under hardware engineering.

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.

As engineering leaders, we value diversity and are committed to building a culture of inclusion to attract and engage innovative thinkers. Our technology, meant to serve all of humanity, cannot succeed if those who built it do not mirror the diversity of the communities we serve. Applications from women, minorities, and other under-represented groups are encouraged.
