About the role

D-Wave is seeking a mechanical engineer to join our New Haven engineering team and contribute to the design and development of advanced hardware for state-of-the-art quantum computing systems. In this role, you will work hands‑on with complex cryogenic, vacuum, and electromechanical systems, helping transform ambitious engineering concepts into reliable, buildable hardware. You will collaborate across engineering, manufacturing, and experimentation in a lab environment where mechanical design plays a critical role in advancing quantum technology.

What you'll do

• Design, prototype, test, and improve mechanical components and system subassemblies for complex electromechanical systems


• Develop and maintain CAD models, detailed drawings, bills of materials, and supporting documentation for prototype builds, design reviews, and released designs


• Apply mechanical engineering principles, including tolerance analysis, materials selection, and design for manufacturability and assembly (DFM/DFA)


• Evaluate thermal design constraints for mechanical and electromechanical hardware, including CTE mismatch, bolted‑joint behavior, heat‑transfer paths, electronics enclosure cooling, and cryogenic component thermalization, using hand calculations, test data, FEA/CFD, and other simulation tools as needed


• Support hands‑on assembly, integration, testing, and troubleshooting of prototype and system hardware; document test results, assembly methods, design changes, and lessons learned


• Collaborate with internal teams and suppliers to develop reliable, practical mechanical solutions and resolve fabrication, fit, assembly, and performance issues

About You

• Bachelor’s degree in Mechanical Engineering, or equivalent training and experience


• 3+ years of professional experience in mechanical design or mechanical engineering, with demonstrated ability to independently drive assigned design tasks from concept through build, test, documentation, and release


• Solid modeling experience in a professional CAD system


• Experience creating and interpreting detailed mechanical drawings, including tolerances, fits, and GD&T


• Proficiency designing machined and sheet‑metal components


• Demonstrated hands‑on mechanical aptitude through lab work, fabrication, equipment maintenance, machining, or similar practical experience


• Ability to perform first‑order engineering analyses and clearly communicate assumptions, results, and design tradeoffs


• Strong engineering judgment, critical thinking, problem‑solving, and communication skills
