This isn’t just about calling an API; it’s about engineering the plumbing, the memory, and the reasoning logic that allows AI to navigate complex datasets. You will be responsible for delivering fast, brilliant, and architecturally sound solutions.\nWhat You’ll Own:\n Cognitive Architecture: Beyond simple prompts, you will engineer the decision-making loops (agents) that allow our tools to self-correct and execute multi-step coding tasks.\nContext Engineering: Develop the retrieval and embedding logic that ensures the model “sees” the right data at the right time, minimizing noise and maximizing signal.\nSystem Integrity: Move beyond “vibe-based” testing. You’ll build rigorous, automated frameworks to quantify model behavior and prevent regressions in production.\nModel Lifecycle: Own the decision between fine-tuning a specialized small model versus orchestrating a frontier LLM, balancing latency with reasoning depth.\nTechnical Leadership: Act as the “Engineer’s Engineer,” setting the standard for how we write production-grade ML code and mentor the team on high-stakes delivery.\nYour Technical Toolkit :\n The GenAI Stack: Extensive experience with the “Agentic” ecosystem (orchestration frameworks, vector-native databases, and semantic search).\nProduction ML: A history of shipping models that actually handle traffic. You know that “done” means deployed, monitored, and stable.\n Code-Fluent: You are a strong software engineer. You are as comfortable in the depths of a Python backend as you are tweaking a model’s temperature. Familiarity with JVM-based languages (Java/Kotlin) is a significant edge.\nThe Scientific Method: You don’t guess; you experiment. You have a background in statistical validation and know how to prove a model’s value via data.\nWhy You’re a Fit :\nYou find the “unknowns” of Agentic AI exciting, not paralyzing.\nYou believe that a model is only as good as the data pipeline feeding it.\nYou are tired of “wrapper” apps and want to build deep, integrated AI systems.\nYou have 5+ years of total ML experience, with a heavy recent focus on the LLM frontier.","description_format":"text","description_chars":2159,"description_truncated":false,"requirements":{"experience_years_min":5,"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":"2026-10-20T08:39:06Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.117,"p_room":0.28,"age_days":250,"expected_fill_days":27,"reasons":["conf:2","agency","win:tail","crowd:"],"computed_at":"2026-10-20T20:23:51Z"},"pay":null,"html_url":"https://alion.io/job/iforce-senior-machine-learning-systems-engineer","json_url":"https://alion.io/job/iforce-senior-machine-learning-systems-engineer.json","meta":{"generated_at":"2026-10-20T20:23:51Z","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":23590,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":4451670},"rest":"https://alion.io/mcp/rest/get_company?id=4451670"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fiforce-senior-machine-learning-systems-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%2Fiforce-senior-machine-learning-systems-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%2Fiforce-senior-machine-learning-systems-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/iforce-senior-machine-learning-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fiforce-senior-machine-learning-systems-engineer"}]}
