This isn't a research role. It's a build role: you're setting up and scaling the systems that let our agents actually run in production, fast and reliably, at increasing concurrency.\nYou report to Sofus and work closely with our ML and infra teams.\nWhat You’ll Own\nSet up and scale inference/Ray Serve for ML and LLM model serving, integrated with our data analysis and agent workflows\nScale agent GPU infrastructure for concurrency and efficiency across multiple agent workloads\nOptimize and improve the engine builder and model server that power scalable agent orchestration\nWhat You Need\nProven ability to build scalable ML/AI platforms from scratch, end-to-end, for production use cases. You've owned a zero-to-one build before, or can show you're capable of it\nDeep understanding of the inference stack: vLLM, KV cache, and the optimization layers underneath model serving\nExperience building distributed systems for AI/ML workloads at scale, connecting them to real product or vertical integrations\n3+ years of relevant experience. We care about capability, not tenure\nNice to Have\nRay / Ray Serve experience\nFamiliarity with AIBrix\nWhy Join\nA rare chance to shape both company and product direction as an early team engineer\nWork alongside engineers and researchers from LinkedIn, Visa, Meta, and Branch\nOnsite culture in San Mateo, built for deep collaboration and high-velocity building\nFull benefits (medical, dental, vision, 401k)\nWe sponsor H-1B visas and assist with immigration","description_format":"text","description_chars":1576,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Knowledge Graphs"],"lifecycle":[{"event":"open","at":"2026-09-11T19:26:33Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 5","filings_12m":5,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":197500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":3}],"liveness":{"score":16,"band":"cold","label":"Long shot","p_open":1,"p_active":0.566,"p_room":0.28,"age_days":469,"expected_fill_days":231,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/zaimler-ml-infrastructure-engineer","json_url":"https://alion.io/job/zaimler-ml-infrastructure-engineer.json","meta":{"generated_at":"2026-11-04T02:26:36Z","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":3701,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"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":687658},"rest":"https://alion.io/mcp/rest/get_company?id=687658"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzaimler-ml-infrastructure-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%2Fzaimler-ml-infrastructure-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%2Fzaimler-ml-infrastructure-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/zaimler-ml-infrastructure-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzaimler-ml-infrastructure-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":764191}},{"tool":"search_jobs","arguments":{"company":"zaimler.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":764191},"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.
