As a Senior AI Framework Engineer, you will own and evolve core APIs and developer experience for inference and training of AI models. You will work at the intersection of API design, systems engineering, and modern AI frameworks. Your output will be the specifications, abstractions, and reference implementations that make MAX feel coherent, powerful, and intuitive to use.\nMissions\nEvoluer et améliorer les API et l'expérience développeur pour l'inférence et l'entraînement des modèles d'IA.\nConcevoir des API d'inférence et d'entraînement qui répondent aux besoins du monde réel et qui évoluent de l'exécution sur un seul appareil à l'exécution distribuée.\nRédiger et socialiser des propositions, recueillir des commentaires et itérer vers un consensus en collaboration avec des équipes interfonctionnelles.\nProfil recherché\n - Experience with inference and training systems (model execution graphs, compilation, runtime scheduling, distributed execution, checkpointing, performance tuning)- Strong understanding of modern AI frameworks and their design tradeoffs (e.g., PyTorch, JAX, TensorFlow, vLLM, XLA/MLIR-adjacent ecosystems)\n- Strong written communication: you can write specs that engineers can implement without ambiguity\n- Significant experience designing and evolving developer-facing APIs (SDKs, frameworks, or platforms)\n- High engineering standards, pragmatism, and a bias towards incremental development without compromising long term design\n- Fluency in one or more systems / performance languages (C++, Rust, Go) and one or more user-facing languages (Python; familiarity with Mojo is a plus)\n- Excellent taste for API ergonomics: naming, composability, types, error handling, configurability, and clarity\n- For candidates who fall outside of the listed requirements, we nevertheless encourage you to apply, as we may have openings at lower or higher levels than the one advertised","description_format":"text","description_chars":1980,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","LLM & Generative AI","AI Agents","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-10-07T13:01:00Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 16 · green card filings: 1","filings_12m":16,"filings_prev_12m":11,"green_card_filings_12m":1,"median_offered_wage_usd":220147,"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)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":10}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":11,"expected_fill_days":35,"reasons":["conf:1","win:early"],"computed_at":"2026-10-13T05:45:00Z"},"pay":{"stated_usd_annual":324000,"is_top_pay":true},"html_url":"https://alion.io/job/modular-senior-ai-framework-engineer","json_url":"https://alion.io/job/modular-senior-ai-framework-engineer.json","meta":{"generated_at":"2026-10-13T13:46:32Z","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":21153,"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":12469},"rest":"https://alion.io/mcp/rest/get_company?id=12469"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmodular-senior-ai-framework-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%2Fmodular-senior-ai-framework-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%2Fmodular-senior-ai-framework-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/modular-senior-ai-framework-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmodular-senior-ai-framework-engineer"}]}
