Mechanical Designer Level 2

About Nord Quantique

At Nord Quantique, we strive to build impactful technology by relentlessly pushing our understanding of quantum science. We are an interdisciplinary team of scientists, engineers, innovators, builders, and enthusiasts on a mission to make quantum computing a reality. Our quantum processors are designed to reduce errors in quantum computation to facilitate long-term scaling toward fully-fledged quantum computers. We believe it is our responsibility to deliver this transformative technology for the greater good of society.

Located at the heart of the beautiful Eastern Townships region in the province of Quebec, Canada, we develop our technology in the vibrant quantum ecosystem of Sherbrooke. Leaning on more than a decade of vertical integration of quantum hardware, we are leveraging a comprehensive pool of quantum technology and micro-electronic infrastructure to deploy our quantum computing technology.

Our current needs

As 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 the CAD of the cryogenic dilution refrigerators setups, assemblies of 3D resonator cavities and structural and thermal analysis of those.

Key responsibilities:

• Design precision mechanical assemblies and miniature structural components for the Quantum Processing Units (QPU) operating at cryogenic temperatures, including consideration of differential CTE behavior, preload stability and thermalization.
• Design and CAD the cryogenic setup for dilution refrigerators that host the QPUs.
• Explore precision design approaches including flexure-based mechanisms, deterministic constraint, kinematic mounting, monolithic structures, and repeatable alignment methods.
• Develop CAD models, technical drawings and tolerance stack-ups for tightly toleranced components of the cavity assemblies and fridge components.
• Conduct structural and thermal analysis of the assemblies to validate the load capacity, thermal performance, stress distribution, and deformation during cooldown.
• Optimize designs for manufacturability, assembly repeatability, scalability, and long-term system reliability.
• Design for assembly by developing standardized and repeatable assembly procedures for the QPU and dilution refrigerators.
• Maintain and organize CAD libraries, technical drawings and documentation, revision control, and manufacturing records to support scalable hardware development.
• Collaborate closely with cross-functional teams including Design Team and Quantum Hardware Team to iterate on the mechanical designs of the system.
• Coordinate with external suppliers to support fabrication, sourcing, and integration of the designs.

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.

Education and experience requirements:

• Bachelor’s degree (BSc) or Master’s degree (MSc) in Mechanical Engineering or in related field with minimum 4 years of mechanical design experience.
• Must have R&D industry experience, preferably within scientific instrumentation, cryogenic, space systems, semiconductor equipment or other precision engineering industries, with a proven track record of working with interdisciplinary teams.

Sought expertise and knowledge:

• Experience designing precision mechanical hardware and tightly toleranced assemblies.
• Understanding of preload control and differential CTE behaviour effects.
• Understanding of manufacturability, assembly repeatability, and long-term hardware reliability.
• Experience creating CAD designs, engineering drawings, and assembly documentation using SolidWorks, Onshape, or similar CAD software.
• Experience with revision control in CAD.
• Experience with stress and thermal analysis using Finite Element Method.
• Ability to work effectively in fast-paced interdisciplinary R&D environments and deliver results within tight deadlines.
• Advanced English proficiency is required. Advanced French proficiency is an asset.

Sought profile:

• 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.

Nord Quantique is committed to the principles of equity, diversity, and inclusion in its training, workplaces, and activities. We encourage applications from diverse backgrounds and traditionally marginalized groups.
