Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems. \nQuantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries. \nOur architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry-including partners like GlobalFoundries-we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure. \nIn 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining-and that now is the time to scale. \nPsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies-including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical-to prepare quantum solutions for real-world impact. \nQuantum computing is not an extension of classical computing. It represents a fundamental shift-and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real. \nCome join us. \nJob Summary:\nSuperconducting nanowire single photon detectors (SNSPD) are a key technology that are mandatory for the development of photonic quantum computers. The job will involve large-scale analysis of SNSPD data and film metrology and design of experiments informed by microscopic superconductivity theory to make improvements to SNSPD devices and materials. The job would involve close interaction with multiple teams spanning material science, fabrication ,testing and layout to deploy SNSPD’s at scale for the development of fault-tolerant quantum computers.\nResponsibilities:\nThe role will require large-scale analysis of SNSPD data based on a deep understanding of SNSPD physics, spanning microscopic theories of superconductivity as well as phenomenological models suitable for devices. The analyzed data will be used to deploy future material design and device design tape-outs for scalable, high performance and high temperature operation.\nExperience/Qualifications:\n>5 years experience in the design and development of SNSPDs , or in adjacent areas involving microscopic theory of superconductivity or condensed matter physics or superconducting device design. A PhD in a technical discipline is preferred but not necessary.\nPsiQuantum provides equal employment opportunity for all applicants and employees.

Please report any suspicious activity  .\nWe are not accepting unsolicited resumes from employment agencies.","description_format":"text","description_chars":4012,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Manufacturing"],"lifecycle":[{"event":"open","at":"2026-10-08T18:03:05Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 23","filings_12m":23,"filings_prev_12m":15,"green_card_filings_12m":0,"median_offered_wage_usd":157500,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":4,"expected_fill_days":133,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/psiquantum-senior-rd-engineer","json_url":"https://alion.io/job/psiquantum-senior-rd-engineer.json","meta":{"generated_at":"2026-10-13T19:39:44Z","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":30046,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":1616},"rest":"https://alion.io/mcp/rest/get_company?id=1616"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpsiquantum-senior-rd-engineer"},{"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%2Fpsiquantum-senior-rd-engineer"},{"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%2Fpsiquantum-senior-rd-engineer"},{"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/psiquantum-senior-rd-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpsiquantum-senior-rd-engineer"}]}
