As we scale from tens of qubits to thousands, our chip-design software becomes the backbone of the entire design pipeline, and it has to support chips that could never be drawn by hand.\nAbout the Role\nAs a Scientific Software Engineer in the Design and Implementation team, you’ll own the internal framework our engineers use to turn a quantum circuit into a layout and send it to electromagnetic and circuit simulators. You’ll keep it robust and fast, grow its component library, and build the automation our layout and scale-up engineers need to design large chips.\nResponsibilities\nOwn and maintain the internal design backend API and qubit design framework: code quality, testing, CI, releases, documentation\nDevelop new parametric components and layout primitives with the chip designers who use them\nExtend and harden the export pipeline to electromagnetic and circuit simulation tools\nBuild the automation layer for large-scale, hierarchical chip layouts in close partnership with our physical-design and scale-up engineers\nSupport internal users: onboarding, debugging, API design, and turning recurring pain points into features\nRequirements\n5+ years of professional Python development, with strong software engineering fundamentals: testing, packaging, versioning, CI/CD, code review\nSolid experience building and maintaining a library or framework used by other engineers, and a taste for clean, well-documented APIs\nComfort with computational geometry or CAD/layout data (GDSII, polygons, transformations) - or eagerness to learn it fast\nAbility to work closely with hardware engineers and translate their needs into software\nFluent English and excellent written and verbal communication skills\nNice to have:\nExperience with gdstk, gdsfactory, KLayout, or other layout tooling\nFamiliarity with electromagnetic simulation tools (HFSS/AEDT, Palace) or circuit simulators\nBackground in superconducting circuits, RF/microwave engineering, or semiconductor design automation (EDA)\nRecruitment Process\nScreening Call with Grace, Talent Acquisition Specialist (30 min)\nHiring Manager Interview with Felix (45 min)\nTechnical Interview/Presentation with the Team (120 min)\nLeadership Team Interview (30 min)\nFit Interview (45 min)\nReference check","description_format":"text","description_chars":2320,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-11-06T18:33:41Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":71,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-11-08T05:47:12Z"},"pay":null,"html_url":"https://alion.io/job/alice-bob-scientific-software-engineer","json_url":"https://alion.io/job/alice-bob-scientific-software-engineer.json","meta":{"generated_at":"2026-11-08T11:24:53Z","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":24552,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-09T00:00:00Z"}},"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":1906},"rest":"https://alion.io/mcp/rest/get_company?id=1906"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Falice-bob-scientific-software-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%2Falice-bob-scientific-software-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%2Falice-bob-scientific-software-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/alice-bob-scientific-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Falice-bob-scientific-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3882304}},{"tool":"search_jobs","arguments":{"company":"alice-bob.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3882304},"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.
