Ottawa, ON (on-site) Employment type: Co-op / Internship Duration: 48 months (depending on academic program) Hours: 3540 hours per week Salary range: $18 $25 CAD per hour, based on academic level and relevant experience About Q-Block Computing: The company develops quantum timing, quantum-secure communications, and quantum computing platforms engineered for the performance, reliability, and environmental resilience that mission-critical applications demand systems designed to be deployed, maintained, and trusted by operators who cannot afford ambiguity about whether the technology works. The long-term vision is deeper than any single platform. The Mechanical CAD Engineering Intern will work alongside Q-Block's engineering team on the mechanical and optomechanical design of quantum hardware precision components and assemblies that have to perform under demanding environmental constraints, including ultra-high vacuum, thermal extremes, and other conditions where casual design choices do not survive. The role is hands-on CAD work with real consequences: the parts you model will be machined, assembled, tested, and iterated. The successful candidate is a motivated mechanical engineering student with solid CAD fundamentals, genuine curiosity about precision hardware, and the discipline to document work carefully as they go. Design and model precision mechanical and optomechanical components using SolidWorks, Autodesk Inventor, CATIA, or comparable CAD software. Develop detailed technical drawings and 3D assemblies for engineering projects across Q-Block's hardware programs. Work with exotic and precision-grade materials (titanium, Invar, stainless steels, aluminum alloys, ceramics, composites)



with attention to manufacturability and structural integrity. Apply appropriate tolerancing, fits, and fastening practices for optics-grade and quantum hardware assemblies. Collaborate with engineers and scientists to translate requirements into clean, manufacturable mechanical solutions. Assist with prototype build-up, test fits, and validation activities as needed. Contribute to a culture of craftsmanship, learning, and honest technical discussion. Currently enrolled in a Mechanical Engineering, Mechatronics, Engineering Physics, or closely related undergraduate program. Demonstrated academic or project experience in mechanical design using CAD software. Proficiency in 3D CAD modeling and technical drawing (SolidWorks, Inventor, CATIA, AutoCAD, or equivalent). Working understanding of tolerancing, fits, and mechanical fasteners. Familiarity with basic materials selection for mechanical design. Coursework or project exposure to optomechanical design, vacuum-compatible engineering, or aerospace mechanical design. Experience with CAM software and practical understanding of CNC machining principles. Familiarity with FEA tools and thermal or structural simulation software. Hands-on fabrication, workshop, or laboratory experience (student design teams, maker-spaces, research labs). Portfolio of CAD models,



technical drawings, or documented design projects. Security and compliance requirements Must be eligible to obtain and maintain Government of Canada security clearance, if required for assigned projects. Must be eligible to comply with requirements of the Controlled Goods Program, if required for assigned projects. Skills and attributes Detail-oriented, with a commitment to precise engineering documentation and process. Initiative and flexibility to adapt as project priorities evolve. What you will gain Direct mentorship from senior mechanical and quantum hardware engineers. Exposure to the full arc from CAD model to machined, assembled, and tested hardware. Professional development, networking within the quantum and deep-tech community, and potential consideration for future co-op terms or full time employment. Competitive hourly compensation based on academic level and relevant experience Extended health care (including dental and vision) Life insurance Application requirements Resume detailing relevant coursework, engineering projects, and technical skills. Brief cover letter describing your interest in mechanical engineering, quantum hardware, and design for demanding environments. Academic transcript (unofficial accepted). Portfolio of CAD models, technical drawings, or past design projects (links preferred). Equal opportunity Q-Block Computing is an equal opportunity employer committed to fostering inclusion and respect. Accommodations are available on request during the application and interview process. All interested students meeting the qualifications are encouraged to apply.
