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.\nThe long-term vision is deeper than any single platform. Q-Block is pursuing a mission to decode Nature's foundational model - to build instruments of sufficient precision and coherence that they become tools for understanding the physical universe at its most fundamental level. Commercialization and science reinforce each other by design.\nAbout this role: 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.\nThe 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. This is a co-op designed to build depth - not to watch from the sidelines.\nResponsibilities\nDesign and model precision mechanical and optomechanical components using SolidWorks, Autodesk Inventor, CATIA, or comparable CAD software.\nDevelop detailed technical drawings and 3D assemblies for engineering projects across Q-Block's hardware programs.\nSupport the design and prototyping of components intended for demanding operating environments, including UHV compatibility, thermal extremes, and related constraints.\nWork with exotic and precision-grade materials (titanium, Invar, stainless steels, aluminum alloys, ceramics, composites) with attention to manufacturability and structural integrity.\nApply appropriate tolerancing, fits, and fastening practices for optics-grade and quantum hardware assemblies.\nCollaborate with engineers and scientists to translate requirements into clean, manufacturable mechanical solutions.\nParticipate in design reviews and iterate on designs based on review feedback.\nDocument design decisions, part specifications, and validation results.\nAssist with prototype build-up, test fits, and validation activities as needed.\nContribute to a culture of craftsmanship, learning, and honest technical discussion.\nRequired qualifications\nCurrently enrolled in a Mechanical Engineering, Mechatronics, Engineering Physics, or closely related undergraduate program.\nMinimum completion of 2nd year coursework (60+ credit hours) at the start of the work term.\nDemonstrated academic or project experience in mechanical design using CAD software.\nProficiency in 3D CAD modeling and technical drawing (SolidWorks, Inventor, CATIA, AutoCAD, or equivalent).\nWorking understanding of tolerancing, fits, and mechanical fasteners.\nFamiliarity with basic materials selection for mechanical design.\nPreferred qualifications\nCoursework or project exposure to optomechanical design, vacuum-compatible engineering, or aerospace mechanical design.\nExperience with CAM software and practical understanding of CNC machining principles.\nFamiliarity with FEA tools and thermal or structural simulation software.\nHands-on fabrication, workshop, or laboratory experience (student design teams, maker-spaces, research labs).\nExposure to design-for-manufacturability practices.\nPortfolio of CAD models, technical drawings, or documented design projects.\nSecurity and compliance requirements\nMust be eligible to obtain and maintain Government of Canada security clearance, if required for assigned projects.\nMust be eligible to comply with requirements of the Controlled Goods Program, if required for assigned projects.\nMust be willing to participate in background screening, documentation, and compliance processes associated with security-sensitive work.\nSkills and attributes\nDetail-oriented, with a commitment to precise engineering documentation and process.\nStrong analytical and problem-solving skills.\nClear written and verbal communication; able to present design decisions and accept feedback.\nInitiative and flexibility to adapt as project priorities evolve.\nStrong interpersonal skills and the ability to work collaboratively in a dynamic, multidisciplinary team.\nWhat you will gain\nDirect mentorship from senior mechanical and quantum hardware engineers.\nHands-on experience designing for demanding operating environments.\nExposure to the full arc from CAD model to machined, assembled, and tested hardware.\nProfessional development, networking within the quantum and deep-tech community, and potential consideration for future co-op terms or full-time employment.\nBenefits\nCompetitive hourly compensation based on academic level and relevant experience\nExtended health care (including dental and vision)\nLife insurance\nApplication requirements\nResume detailing relevant coursework, engineering projects, and technical skills.\nBrief cover letter describing your interest in mechanical engineering, quantum hardware, and design for demanding environments.\nAcademic transcript (unofficial accepted).\nPortfolio of CAD models, technical drawings, or past design projects (links preferred).\nEqual opportunity\nQ-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.","description_format":"text","description_chars":6110,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Life insurance","Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-10-02T14:47:43Z"}],"visa":[],"liveness":{"score":2,"band":"cold","label":"Long shot","p_open":1,"p_active":0.085,"p_room":0.28,"age_days":183,"expected_fill_days":35,"reasons":["conf:2","stale_co","ghost","win:tail","crowd:junior"],"computed_at":"2026-10-20T05:45:00Z"},"pay":{"stated_usd_annual":36000,"is_top_pay":false},"html_url":"https://alion.io/job/q-block-mechanical-cad-engineering-intern","json_url":"https://alion.io/job/q-block-mechanical-cad-engineering-intern.json","meta":{"generated_at":"2026-10-21T05:00:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":7384,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2504443},"rest":"https://alion.io/mcp/rest/get_company?id=2504443"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fq-block-mechanical-cad-engineering-intern"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fq-block-mechanical-cad-engineering-intern"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fq-block-mechanical-cad-engineering-intern"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/q-block-mechanical-cad-engineering-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fq-block-mechanical-cad-engineering-intern"}]}
