Job Description
Rigetti Computing is at the forefront of building scalable quantum computers. We are seeking a Lead 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 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
- Lead 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
$170000 - $215000 a year
