Job description
Rigetti Computing is at the forefront of building scalable quantum computers. We are seeking a Senior Mechanical Engineer to architect, design, develop, and optimize advanced hardware systems that form the backbone of our next-generation quantum computing platforms. In this role, you will lead the mechanical design and integration of hardware that enables RF signal delivery and silicon device packaging within dilution refrigerators. These systems form the critical interface between room-temperature control electronics and ultra-low-temperature environments where superconducting qubits operate. You will collaborate closely with quantum device physicists, electrical/RF engineers, systems integration teams, and external fabrication partners to deliver innovative, high-performance mechanical systems for customer-deployed quantum computers.
Key Responsibilities: System Design & Development
Senior the mechanical design of complex hardware subsystems including cryostat internal architecture, custom components for signal chain and metal enclosures
Develop and maintain detailed 3D CAD models, drawings, and Bills of Materials (BOMs)
Drive end-to-end design of mechanical interfaces from room temperature down to the millikelvin regime
Design thermal anchoring and shielding systems optimized for mechanical stability and quantum coherence
Perform thermal, vibrational, and structural simulations using FEA tools to ensure performance and robustness
Build and validate mechanical/cryogenic prototypes in lab
Collaborate with quantum physics teams to ensure system-level functionality in live quantum experiments
Work closely with hardware, cryo, RF, and systems teams to deliver integrated, scalable quantum hardware platforms
Develop specifications for outsourced components and manage supplier relationships for critical assemblies such as vacuum flanges, cryo fixtures, and RF housings
Author assembly documentation, and maintain design traceability in PLM system
Required Qualifications
M.S. degree or higher in Mechanical Engineering or equivalent field
7+ years of industry experience in mechanical design and systems engineering
Proficiency with 3D CAD software (SolidWorks preferred)
Strong background in tolerance analysis and GD&T principles
Experience in thermal and structural modeling and simulation
Familiarity with documentation control, revision management, and PLM tools
Excellent cross-disciplinary communication and project collaboration skills
Demonstrated ability to develop and document assembly processes
Preferred Qualifications
Familiarity with thermal-mechanical effects in cryogenic materials and multi-physics system design
Experience with RF packaging and electronic device integration in cryogenic or vacuum environments
Quality assurance experience including inspection methodologies and non-conformance resolution
Hands-on machining or fabrication experience to support rapid prototyping and design iteration
$165,000 - $190,000 a year
Base Salary
Rigetti offers a full slate of benefits from competitive salaries, equity, medical, dental and vision for employees as well as a 401(k) plan, a paid parental leave program, rejuvenation days, and avacation policy that aligns with local regulations and industry standards.
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.
