As a Senior Mechanical Designer – Cryomechanical Systems You will own products from cradle to grave, working hands on to oversee initial builds, incorporating customer feedback to make improvements and driving continuous improvements to equipment as the state-of-the-art advances. You help shape requirements, create complete three-dimensional (3D) models from scratch, produce two-dimensional (2D) drawings, document Bill of Materials (BOM), create standard operating procedures (SOPs) and work hands on in installations to guide products through their entire lifecycle.

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.

Responsibilities

• Own 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 managemen
