In this role, you will work at the intersection of AI, infrastructure, and external partners. You will be responsible for building Pi's model API end to end, designing scalable systems, and turning partner data into a first-class product experience. You will also work closely with researchers to turn new model capabilities into stable, usable product surfaces. This is an exciting opportunity to shape the future of general-purpose robotics.\nMissions\nConcevoir et construire l'API de modèle de Pi de bout en bout, y compris l'ingestion de données, le réglage fin, l'évaluation, l'inférence à faible latence.\nArchitecturer une infrastructure multi-locataire fiable autour de la limitation de débit, de l'isolation, de la pression de retour, de la version, de l'observabilité.\nTravailler en étroite collaboration avec les chercheurs pour transformer les nouvelles capacités du modèle en surfaces de produit stables et utilisables.\nProfil recherché\n - Enough familiarity with machine learning systems to deploy, serve, and debug models in production. You do not need to be an ML researcher- An understanding of the problems that emerge as systems scale: reliability, latency, multi-tenancy, versioning, observability, and operational complexity\n- Strong software engineering fundamentals and experience building production systems\n- Strong Python skills and the ability to work comfortably across infrastructure and product boundaries\n- A high degree of ownership. You’re comfortable taking an ambiguous problem, building the first version end to end, and then designing the system so it no longer depends on you\n- Experience building and scaling developer platforms. We’re especially interested in people who have shipped platforms for model fine-tuning, inference, or other compute-intensive workloads\n- Deep backend and systems experience across APIs, services, databases, caching, distributed systems, and infrastructure\n- Experience with security, authentication, authorization, or multi-tenant infrastructure\n- Familiarity with our stack: Python, Postgres, ClickHouse, GCP, Kubernetes, Modal, React, and TypeScript\n- Experience building model-serving, inference, fine-tuning, or developer-platform infrastructure\n- Experience at an early-stage infrastructure, AI, robotics, or autonomous systems company\n- Experience building low-latency or real-time systems, including streaming, inference transport, WebSockets, QUIC, or similar technologies","description_format":"text","description_chars":2529,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-10T01:39:25Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":0,"expected_fill_days":21,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/p-machine-learning-engineer-api-platform","json_url":"https://alion.io/job/p-machine-learning-engineer-api-platform.json","meta":{"generated_at":"2026-10-12T01:43:41Z","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":2282,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":3908685},"rest":"https://alion.io/mcp/rest/get_company?id=3908685"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fp-machine-learning-engineer-api-platform"},{"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%2Fp-machine-learning-engineer-api-platform"},{"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%2Fp-machine-learning-engineer-api-platform"},{"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/p-machine-learning-engineer-api-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fp-machine-learning-engineer-api-platform"}]}
