Mechanical Designer, Cryogenic Systems - Mid-Level

Mechanical Designer, Cryogenic Systems - Mid-level at Nord Quantique, Sherbrooke, QC, Canada. A mid-level full time position in the Design team, listed under hardware engineering.
Our current needsAs we scale up our quantum processors and supporting infrastructure, we are seeking a skilled and self-driven Mechanical Designer to join our Mechanical Design and Manufacturing Team. This role focuses on precision mechanical design and mechanical/thermal analysis of cryogenic quantum hardware, including dilution refrigerator setups, QPU assemblies, and 3D resonator cavities. The ideal candidate has experience designing precision hardware for demanding environments such as cryogenics, scientific instrumentation, semiconductor equipment, optics/photonics, aerospace and space systems, or other high-precision engineering applications. Direct quantum experience is an asset, but not required. This is a dynamic role within a fast-paced, research-driven environment, offering the opportunity to contribute directly to the advancement of scalable quantum hardware.
Working closely with the mechanical design team, the successful candidate will be responsible for:
Design precision mechanical assemblies and miniature structural components for the Quantum Processing Units (QPU) operating at cryogenic temperatures ~20mK range, including thermal analysis for differential CTE behavior and thermalization.
Develop precision mechanical solutions using flexures, kinematic mounts, deterministic constraints, and repeatable alignment methods including consideration of thermal contraction, differential CTE and tolerance accumulation.
Perform structural and thermo-mechanical analysis of the assemblies using FEA to validate the load capacity, thermal performance, stress distribution, and deformation in the system.
Design the cryogenic setup for dilution refrigerators that host the QPUs, including supports, mechanical interfaces, thermal anchoring, and alignment features.
Optimize designs for manufacturability, assembly repeatability, scalability, and long-term system reliability.
Requirements
Bachelor’s degree (BSc) or Master’s degree (MSc) in Mechanical Engineering or in related field with minimum 5 years of mechanical design experience.
Must have R&D industry experience, preferably within quantum hardware, scientific instrumentation, cryogenic system, aerospace/space systems, semiconductor equipment or other precision engineering industries, with a proven track record of working with interdisciplinary teams.
Great sense of autonomy and dependability
Proficient in producing clear and concise technical reports
Excellent organizational and prioritization skills focused on achieving company objectives
Willingness to learn and explore new concepts
Strong communication and collaboration skills to work effectively with cross-functional teams, external vendors, suppliers, and development partners
Team-oriented mindset with a focus on cooperation and knowledge sharing within the team.
