Acting as a technical leader within the team, you will drive architectural decisions, champion engineering best practices, and mentor junior engineers to support their professional growth. You will be in charge of developing the low level of our stack, as close as possible to our hardware.\nYour work will be central in bridging scientific R&D, data engineering, and production-grade platform design while enabling researchers and physicists to iterate rapidly without compromising reliability.\nResponsibilities\nDesign and maintain low-level drivers and hardware abstraction layers for control electronics - including signal generators, AWGs, digitizers, and custom FPGA-based instruments.\nDefine clean hardware/software interfaces that decouple control electronics from higher-level experiment logic, enabling fast hardware iteration without breaking the software stack.\nCollaborate closely with physicists and researchers to ensure models and interfaces reflect real experimental needs and enable fast iteration.\nDrive long-term architectural strategy, technical roadmap, and cross-organizational alignment.\nMentor teams, challenge assumptions, and lead architecture reviews across the platform department.\nRequirements\n8+ years experience designing low level software stack, close to the hardware.\nSuperior engineering proficiency in Python\nAbility to define clean abstractions and synchronization mechanisms for hardware/software interaction loops - including real-time constraints, timing accuracy, and low-latency communication with control hardware.\nHands-on experience writing drivers or low-level interfaces for hardware instruments (e.g. via VISA, SCPI, PCIe, Ethernet/UDP, or custom protocols).\nSolid understanding of Digital Signal Processing (DSP) fundamentals - sampling, filtering, modulation/demodulation, and their application to waveform generation and acquisition.\nAbility to collaborate and challenge ideas with physicists, academic-level experts, and deeply technical researchers.\nStrong technical leadership: able to influence direction, align teams, and support cross-domain decision-making.\nNice to have :\nHands-on experience with automation systems (schedulers, workflow engines, configuration graphs, data pipelines).\nStrong product mindset: ability to think about end-to-end delivery, user experience, reliability, and long-term lifecycle.\nExperience delivering a hardware-backed product (accelerators, HPC nodes, scientific instruments) to external users.\nRecruitment process\nScreening call with Doriane (30 min)\nHiring Manager Interview (45 min)\nTechnical Interview with the Team (60 min)\nLeadership Interview (30 min)\nFit Interview (30 min)","description_format":"text","description_chars":3105,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-09-09T16:32:33Z"}],"visa":[],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":1,"p_active":0.824,"p_room":0.75,"age_days":49,"expected_fill_days":61,"reasons":["conf:1","win:late"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/alice-bob-senior-software-engineer","json_url":"https://alion.io/job/alice-bob-senior-software-engineer.json","meta":{"generated_at":"2026-10-30T02:47:41Z","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":3612,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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-senior-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-senior-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-senior-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-senior-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Falice-bob-senior-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":575242}},{"tool":"search_jobs","arguments":{"company":"alice-bob.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":575242},"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.
