You will focus on building robust routines for coarse tuning, calibrating high-fidelity single- and two-qubit gates, optimizing the full processor at scale, and maintaining peak performance in real time. You will collaborate regularly with other cross-functional teams, such as research, product, and engineering, to apply your insights to a variety of quantum computing challenges and turn your ideas into usable software tools. This position offers the opportunity to work at the forefront of quantum computing, driving innovation and delivering impactful solutions.\nWhat you’ll be doing:\nPerform cryogenic measurements and characterization of quantum dot-based qubits.\nInvent, implement, and test novel control protocols for all the required bring-up steps, starting from coarse tuning to optimizing two-qubit gates.\nDevelop scalable protocols for processor-wide optimization (e.g., cross-talk mitigation, leakage reduction, and defect mitigation) and real-time retuning.\nCollaborate with your colleagues in the engineering and product teams to translate ideas and research outcomes into production-level software.\nExplain, document, and present research solutions in accessible language.\nEngage with researchers at partnering companies and organizations to discuss current and future Q-CTRL calibration routines.\nDrive product development & delivery, translating research innovations into practical solutions.\nIdeally you'll have:\nAn advanced degree in Physics, Engineering, or a closely related discipline. A PhD is preferred, but we also consider exceptional candidates with previous industry experience.\n3+ years of experience conducting research in a relevant field.\nPrevious experience in tune-up and characterization of quantum dots.\nExpertise in numerical techniques, statistical learning, and optimization algorithms.\nA good grasp of software development best practices and experience in developing software modules for qubit measurement and control (Python, C++, Rust). Familiarity with modern AI tools for software is a plus.","description_format":"text","description_chars":2200,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-11-07T01:42:07Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":157500,"route":null,"cap_exempt":false,"checked_at":"2026-11-10T11:34:35+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":1}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":3,"expected_fill_days":33,"reasons":["conf:3","velocity","win:early"],"computed_at":"2026-11-10T06:52:35Z"},"pay":null,"html_url":"https://alion.io/job/q-ctrl-senior-research-scientist-silicon-spin-qubits","json_url":"https://alion.io/job/q-ctrl-senior-research-scientist-silicon-spin-qubits.json","meta":{"generated_at":"2026-11-11T04:04:13Z","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":4019,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":6563},"rest":"https://alion.io/mcp/rest/get_company?id=6563"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fq-ctrl-senior-research-scientist-silicon-spin-qubits"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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-ctrl-senior-research-scientist-silicon-spin-qubits"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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-ctrl-senior-research-scientist-silicon-spin-qubits"},{"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-ctrl-senior-research-scientist-silicon-spin-qubits\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fq-ctrl-senior-research-scientist-silicon-spin-qubits"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3903347}},{"tool":"search_jobs","arguments":{"company":"q-ctrl.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3903347},"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.
