Microsoft Quantum will change the world of computing and help solve some of humankind’s currently unsolvable problems. For more information about our team, visit https://www.microsoft.com/en-us/quantum. The Cryomechanical and Packaging team enables Microsoft Quantum’s hardware roadmap by designing, integrating, and sustaining cryogenic mechanical systems, packaging solutions, and laboratory infrastructure that support reliable experimentation, scalable system integration, and disciplined transition from research concepts to producible hardware. As a Mechanical Designer – Cryomechanical Systems, you will own cryomechanical designs from a blank computer-aided design (CAD) canvas to released drawings and bills of materials (BOMs) for complex assemblies inside and around dilution refrigerators, also known as cryostats. You will create complete three-dimensional (3D) models from scratch, produce two-dimensional (2D) drawings with geometric dimensioning and tolerancing (GD&T) per American Society of Mechanical Engineers (ASME) Y14.5, and drive cross-functional design reviews to release high-quality hardware that meets performance, thermal, vacuum, and integration requirements. Microsoft’s culture is grounded in a growth mindset, customer obsession, diversity and inclusion, one Microsoft collaboration, and making a difference through technology. In this role, you will be expected to model these values by learning continuously, partnering across disciplines, communicating clearly, and creating an inclusive environment where rigorous engineering and shared accountability help the team deliver meaningful impact. ResponsibilitiesOwn end-to-end three-dimensional (3D) computer-aided design (CAD) for cryogenic subassemblies and top-level mechanical integrations, including cold fingers, millikelvin (mK) and 4 kelvin (4 K) stages, radiation shields, vacuum interfaces, and cable or harness routing fixtures; create fully detailed two-dimensional (2D) drawings with geometric dimensioning and tolerancing (GD&T) and tolerance stackups. Build and steward the top assembly and bill of materials (BOM) by managing part numbering, configurations, engineering change order (ECO) and engineering change request (ECR) workflows, and product data management/product lifecycle management (PDM/PLM) toolchains such as SolidWorks, Windchill, and OnePDM. Lead Cryomechanical Engineering (CryoME) design reviews using standard review packages that include three-dimensional (3D) computer-aided design (CAD), two-dimensional (2D) drawings, critical-to-function specifications, materials, coatings, finishes, incoming quality control (IQC), cryogenic screening plans, manufacturing and assembly flows, risks, and schedules. Translate system requirements into mechanical specifications for thermal anchoring, heat-load budgets, coefficient of thermal expansion (CTE) mismatch management, vacuum sealing, vibration isolation, radio frequency (RF) and direct current (DC) cable management, and integration across temperature stages.
