We design and operate full-stack quantum systems, from fabrication and cryogenics to control electronics, calibration, and software. What differentiates Anyon is execution speed, technical depth, and a relentless focus on making quantum hardware work in practice, not just on paper. Our Tel Aviv R&D center is a critical powerhouse driving Anyon Systems’ global quantum roadmap. Far from a traditional satellite office, this strategic hub owns the core pillars of our technology: quantum control, calibration, benchmarking, and AI-first automation. We deliberately anchored this team in Israel to leverage the ecosystem’s unmatched pedigree in deep-tech execution, defense-grade engineering, and rigorous applied research. As a member of this team, you will operate with complete autonomy and high agency, directly shaping the flagship products deployed to our customers worldwide.\nRole Overview:\nThis role focuses on understanding complex multi-qubit dynamics, noise, and emergent behavior as systems scale, with an emphasis on models that can inform real systems.\nKey Responsibilities:\nModel many-body and open quantum system dynamics\nStudy thermalization, crosstalk, and non-equilibrium effects\nDevelop reduced models usable by AI calibration systems\nIdentify scaling bottlenecks and emergent error mechanisms\nCollaborate closely with experimental teams\nQualifications:\nPhD in theoretical physics or related discipline\nExpertise in many-body dynamics or open quantum systems\nStrong analytical and numerical skills\nWhat We Offer:\nA core technical role in a fast-growing quantum hardware company\nDirect access to real, state-of-the-art quantum processors\nHigh level of autonomy and technical ownership\nCollaboration with world-class experimental, theoretical, and AI teams across North America and Israel\nCompetitive compensation aligned with senior deep-tech roles in Israel - Long-term equity participation\nFlexible work culture with strong emphasis on results, not bureaucracy - Opportunity to influence the technical direction of the company\nSecurity / Defense Backgrounds: Candidates with backgrounds in defense, aerospace, intelligence, secure systems, RF, real-time systems, or classified R&D environments are strongly encouraged to apply. Experience operating complex systems under strict performance, reliability, and security constraints is highly valued.","description_format":"text","description_chars":2460,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Flexible schedule"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Science & Engineering","Quantum Science & Computing"],"lifecycle":[{"event":"open","at":"2026-09-07T16:55:59Z"}],"visa":[],"liveness":{"score":23,"band":"cold","label":"Long shot","p_open":1,"p_active":0.632,"p_room":0.36,"age_days":149,"expected_fill_days":92,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/anyon-systems-theoretical-physicist-quantum-systems-many-body-open-systems","json_url":"https://alion.io/job/anyon-systems-theoretical-physicist-quantum-systems-many-body-open-systems.json","meta":{"generated_at":"2026-11-12T23:38:18Z","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":49962,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"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":58222},"rest":"https://alion.io/mcp/rest/get_company?id=58222"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fanyon-systems-theoretical-physicist-quantum-systems-many-body-open-systems"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fanyon-systems-theoretical-physicist-quantum-systems-many-body-open-systems"},{"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%2Fanyon-systems-theoretical-physicist-quantum-systems-many-body-open-systems"},{"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/anyon-systems-theoretical-physicist-quantum-systems-many-body-open-systems\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fanyon-systems-theoretical-physicist-quantum-systems-many-body-open-systems"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":513717}},{"tool":"search_jobs","arguments":{"company":"anyonsys.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":513717},"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.
