We specialize in chip-scale quantum devices, starting with clocks and sensors, that unlock resilient Position, Navigation, and Timing (PNT) for defense, telecom, space, and critical infrastructure. Our team combines world-class expertise in AMO physics, photonics, microfabrication, and engineering to transform breakthrough science into scalable, deployable technology. Backed by top-tier deep-tech investors and the U.S. Department of Defense, Mesa Quantum is rapidly scaling and actively recruiting exceptional innovators who want to build the future of quantum technology from the ground up.\nThe Role\nWe are seeking a hands-on Senior Mechanical Engineer to lead the mechanical and thermal design of our chip-scale atomic clock, from physics package and electronics integration through enclosure and production. You will reduce size, weight, power, and cost (SWaP-C) while ensuring stability and reliability under demanding environmental conditions. You will model, build, and test prototypes, then work with cross-functional teams and manufacturing partners to transition designs into production.\nWhat You Will Do:\n\nOwn system-level mechanical architecture, CAD design, drawings, prototypes, and production release.\nManage mass, volume, and power budgets; run trade studies to reduce SWaP-C without compromising clock stability.\nDevelop thermal designs and models for the vapor cell, laser, and electronics, and correlate predictions with test data.\nDesign for shock, vibration, and thermal cycling; plan and execute environmental tests and implement improvements.\nDevelop vacuum or hermetic packaging, magnetic shielding, and precision alignment for optics and other sensitive components.\nDrive design for manufacturing and assembly, supplier collaboration, assembly documentation, and production readiness.\nCollaborate with physics, photonics, electrical, firmware, and manufacturing teams on current and next-generation clock designs.\nRequirements\nWhat You Bring:\nBS in Mechanical Engineering with 8+ years of relevant experience, or MS/PhD with 5+ years.\nAdvanced SolidWorks or Creo skills, including production drawings and GD&T.\nExperience with thermal and structural FEA using tools such as ANSYS, COMSOL, or SolidWorks Simulation, validated against test data.\nHands-on experience with thermal management, precision hardware, and ruggedization for shock and vibration.\nExperience designing small hardware from prototype through production, including vacuum or hermetic packaging and leak testing.\nAbility to build and test prototypes, document designs clearly, and work directly with machine shops, vendors, and contract manufacturers.\nStrongly Preferred\nExperience with atomic clocks, quantum sensors, magnetometers, or atomic interferometers.\nRugged electronics for defense, aerospace, or space applications, including environmental qualification.\nLow-power thermal design, vacuum insulation, or low-emissivity coatings.\nMEMS or microelectronics packaging, magnetic shielding, laser or photonics packaging, and optical alignment.\nExperience with electronics cooling tools, ECAD/MCAD collaboration, PLM systems, or early-stage hardware companies.\nEligibility\nDue to U.S. Department of Defense funding requirements, applicants must be U.S. persons (U.S. citizens or lawful permanent residents). The ability to obtain and maintain a U.S. security clearance may be required for certain projects.\nBenefits\nBase salary of $140,000 to $195,000, depending on experience and qualifications.\nMeaningful equity and a comprehensive benefits package.\nThe opportunity to own critical product design at the intersection of quantum technology, photonics, and advanced engineering.\nA collaborative team with deep expertise in AMO physics, RF, photonics, and microfabrication, based in Boulder, Colorado.","description_format":"text","description_chars":3922,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":true,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Hardware","Quantum Science & Computing","Sensors & Transducers"],"lifecycle":[{"event":"open","at":"2026-10-27T18:05:00Z"}],"visa":[],"liveness":{"score":95,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.946,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:2","urgency","win:early"],"computed_at":"2026-10-28T05:59:10Z"},"pay":{"stated_usd_annual":195000,"is_top_pay":true},"html_url":"https://alion.io/job/mesa-quantum-sr-mechanical-engineer-us","json_url":"https://alion.io/job/mesa-quantum-sr-mechanical-engineer-us.json","meta":{"generated_at":"2026-10-28T10:47:32Z","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":14061,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":683870},"rest":"https://alion.io/mcp/rest/get_company?id=683870"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmesa-quantum-sr-mechanical-engineer-us"},{"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%2Fmesa-quantum-sr-mechanical-engineer-us"},{"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%2Fmesa-quantum-sr-mechanical-engineer-us"},{"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/mesa-quantum-sr-mechanical-engineer-us\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmesa-quantum-sr-mechanical-engineer-us"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3349117}},{"tool":"search_jobs","arguments":{"company":"mesaquantum.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3349117},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
