As the AI Engineering Lead, you will build the AIOS Agent SDK, a foundation for world-class agents across the company. You will also lead the development of an AI clinical decision-support system and be responsible for agent architecture, model strategy, evaluations, AI reliability, technical safety, provider relationships, and the shared runtime. This is a senior technical leadership role, reporting directly to the VP of Engineering.\nMissions\nConstruire le SDK de l'agent AIOS et en faire la base pour des agents de classe mondiale.\nSéparer les fondations réutilisables de la logique de support client et les transformer en une plateforme interne fortement opinionnée.\nÊtre le responsable de l'architecture des agents, de la stratégie des modèles, des évaluations, de la fiabilité de l'IA, de la sécurité technique.\nProfil recherché\n - Builder: You still write production code. You lead from inside the work rather than managing it from a distance- Model Judgement: You understand the capabilities and limitations of current frontier and open-weight models. You know when the model is the problem and when the real problem is context, tools, data, orchestration, or evaluation\n- Open-Weight Models: You have enough technical depth to lead the fine-tuning and AIOS-controlled deployment of open-weight models when the evidence supports doing so. Prior production deployment is not required\n- Agent Architecture: You can reason deeply about harnesses, orchestration, context construction, retrieval, memory, state, tool design, structured workflows, and error recovery\n- Consequential Actions: You know how to let an agent act safely. You have strong judgment around authorization, validation, idempotency, state transitions, auditability, recovery, and escalation\n- Technical Authority: Strong engineers trust your judgment. You can make difficult decisions, explain the trade-offs clearly, and push back without hesitation when a proposed approach is unsound\n- Communication: You can explain difficult technical ideas to engineers, product leaders, clinicians, and executives without flattening the important details\n- Experience: You have 8+ years of software engineering experience and remain an active production contributor\n- Leadership: You have successfully led and managed a small technical engineering team. You set a clear direction, raise the quality bar, develop strong engineers, and address underperformance\n- Independence: You create clarity in ambiguous environments and make high-quality decisions without hand-holding\n- Software Engineering: You have strong systems-engineering fundamentals. You can reason about APIs, distributed systems, concurrency, queues, databases, observability, failure modes, and production reliability\n- Education: You have at least a bachelor’s degree in Computer Science, Machine Learning, or a closely related technical field\n- Ownership: When quality drops, costs spike, tools fail, or providers degrade, you take responsibility for reaching the outcome rather than identifying whose component was technically at fault\n- Evals: You’ve built or meaningfully owned evaluation systems for probabilistic products. You understand dataset construction, evaluator design, simulations, regression detection, noisy metrics, and the relationship between offline performance and production outcomes\n- Production Agents: You have personally built and shipped an exceptional agentic system used by real customers. It did more than answer questions: it reasoned across multiple steps, used tools, changed state, and operated under real production constraints\n- Customer Agents: You’ve built high-volume customer-service, commerce, or transactional agents operating across complex, multi-step customer journeys\n- Agent Platforms: You’ve built runtimes, SDKs, harnesses, tool layers, evaluation platforms, or shared AI infrastructure used by other engineers\n- High-Stakes Systems: You’ve worked on healthcare, financial, insurance, or other systems where correctness, traceability, and careful rollout matter\n- Model Adaptation: You’ve fine-tuned, distilled, evaluated, or deployed an open-weight model for a specific production workflow\n- Long-Term Memory: You’ve built durable memory, context compression, personalization, or agents operating across sessions and extended periods\n- Real-Time Systems: You’ve worked on voice agents, streaming systems, or other latency-sensitive AI experiences\n- Research Fluency: You can translate relevant research into reliable production systems without confusing novelty with progress\n- Talent: You have a strong nose for exceptional AI engineers and know how to create an environment in which they do their best work\n- Provider Relationships: You’ve worked directly with frontier model providers on evaluations, technical issues, capacity, pricing, or early access\n- Figure It Out: You can move from debugging a production trace, to redesigning an eval, to reviewing an agent abstraction, to handling a provider incident","description_format":"text","description_chars":5062,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-07T13:31:40Z"}],"visa":[],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.617,"p_room":0.28,"age_days":72,"expected_fill_days":34,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":400000,"is_top_pay":true},"html_url":"https://alion.io/job/joinfella-ai-engineering-lead-aios","json_url":"https://alion.io/job/joinfella-ai-engineering-lead-aios.json","meta":{"generated_at":"2026-10-23T08:07:37Z","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":12950,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":3210978},"rest":"https://alion.io/mcp/rest/get_company?id=3210978"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjoinfella-ai-engineering-lead-aios"},{"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%2Fjoinfella-ai-engineering-lead-aios"},{"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%2Fjoinfella-ai-engineering-lead-aios"},{"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/joinfella-ai-engineering-lead-aios\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjoinfella-ai-engineering-lead-aios"}]}
