D-Wave (NYSE: QBTS)

D-Wave is a leader in the development and delivery of quantum computing systems, software, and services. It is the world’s first commercial supplier of quantum computers, offering dual‑platform products spanning both annealing and gate‑model technologies. Its mission is to help customers realize the value of quantum today through enterprise‑grade systems available on‑premises and via its Leap quantum cloud service with 99.9% availability.

Mechanical engineer for the New Haven engineering team, contributing to the design and development of advanced hardware for state‑of‑the‑art quantum computing systems. Work hands‑on with complex cryogenic, vacuum, and electromechanical systems, transforming ambitious engineering concepts into reliable, buildable hardware. Collaborate across engineering, manufacturing, and experimentation in a lab environment.

• 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

• 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 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
• 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
