Mechanical/ Cryogenic Engineer

Job Description

Job Title: Senior Mechanical/Cryogenic Engineer – Quantum Computing Systems. Location: Berkeley, CA (On-site)

Responsibilities:

• Lead mechanical and thermal design of the cryogenic signal path from room temperature down to millikelvin temperatures.
• Engineer robust mechanical structures for cryogenic cabling, filtering, attenuation, and thermal anchoring;
• Work cross-functionally with quantum hardware, RF, and systems teams to align mechanical strategies inside dilution refrigerators.
• Perform system-level simulations to evaluate thermal gradients, vibration effects, and mechanical stability;
• Select and qualify components and materials optimized for cryogenic performance and durability.

Qualifications:

• Bachelor’s or Master’s degree in Mechanical Engineering, Physics, or related field.
• At least 7 years of experience in mechanical system design, with a strong background in electromechanical integration.
• Proficiency in 3D CAD tools (e.g., SolidWorks) and simulation platforms (e.g., COMSOL, ANSYS).
• Demonstrated ability to work across disciplines in fast-paced R&D environments.

Preferred:

• Experience working with superconducting quantum processors or other precision cryogenic platforms.
• Hands-on knowledge of dilution refrigerators and multi-stage cryogenic systems.
• Familiarity with cryogenic interconnect technologies, such as flex cables, coaxial lines, and cryo-compatible filters.

Benefits:

• Salary Range: $150,000 – $180,000 (commensurate with experience and location)
• Equity options
• Medical, dental, and vision insurance
• 401(k) plan
• Paid parental leave
• Rejuvenation days and generous vacation policy
