We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.\nAbout the role\nOur control systems can only act on what the plant knows about itself, and this role is responsible for most of that knowledge. The work includes:\nReinforcement learning agents that learn to control our processes in simulation\n\nTime-series models for forecasting and detection\n\nVision systems that measure things no instrument can\n\nSoft sensors that estimate lab results we can't get back fast enough\n\nClassifiers that flag faults early\n\nYou'll set technical direction for applied ML across our sites and build much of it yourself, from data to deployment. The scope is wide on purpose. We care more about range and good judgment than deep expertise in any single technique.\nWhat you'll work on\nDeciding where ML is worth it. Some problems need a model and many don't. You'll help us put effort where it improves recovery, uptime, or cost.\n\nTime-series work: forecasting, anomaly and excursion detection, predictive maintenance, and soft sensors.\n\nComputer vision on circuits, conveyors, and equipment. Expect poor lighting, vibration, and dirty lenses.\n\nClassification and diagnostics for faults, product quality, and process state. Labels are rare, classes are imbalanced, and some mistakes cost far more than others.\n\nSetting the deployment bar for each model and running the validation that gets it from a notebook into the control room, where operators rely on it during their shift.\n\nWriting the team's modeling standards, reviewing designs, and mentoring engineers at every level.\n\nWorking closely with two teams:\nThe autonomy and controls team, whose controllers use your predictions.\n\nData engineering, who own the platform underneath.\n\nReinforcement learning in our process simulators, training agents to learn how to control each circuit and taking what works from simulation onto the real plant.\n\nWhat we're looking for\n8 to 10+ years in ML engineering, or 6+ with clear org-level technical leadership. You've put models into production in the physical world and kept them running.\n\nShipped work in at least two of these areas: time-series, computer vision, reinforcement learning, and classical supervised learning. You can pick up a third quickly, and you can tell which one a problem actually needs.\n\nExperience with industrial sensor data: historians, SCADA/DCS, OPC-UA, or similar.\n\nExperience with scarce labels, drift, and rare events. You report how uncertain a prediction is, not just a single number.\n\nYou work well with roboticists, chemists, metallurgists, process engineers, and geologists, and you can bring technical leadership along with you.\n\nYou like building. Staff engineers here ship.\n\nWhy join\nWe own our projects and generate our own data, so what you build feeds straight back into operations. Each new facility adds to that data and makes the next one quicker and cheaper to build.\nIn most applied ML jobs, someone hands you a cleaned dataset and a metric. Here you get a plant. You figure out what needs measuring, build the thing that measures it, and see whether the numbers move.\nOur culture is built on four principles:\nEveryone Gets Home Safe. We never put speed or cost ahead of people.\nExtreme Ownership. We take full responsibility for outcomes, relentlessly driving toward solutions.\nEngineer Out Requirements, then Automate. We simplify, optimize, and then automate for scale.\nShare Your Legos. We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.\nJoin us as we build the future of responsible mineral sourcing and supply!","description_format":"text","description_chars":3879,"description_truncated":false,"requirements":{"experience_years_min":8,"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":["Mining","Mining Tech","Non-ferrous Metals"],"lifecycle":[{"event":"open","at":"2026-06-10T23:58:01Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 15","filings_12m":15,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":152500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":3}],"liveness":{"score":14,"band":"cold","label":"Long shot","p_open":1,"p_active":0.49,"p_room":0.28,"age_days":128,"expected_fill_days":40,"reasons":["conf:2","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":false},"html_url":"https://alion.io/job/marianaminerals-staff-machine-learning-engineer","json_url":"https://alion.io/job/marianaminerals-staff-machine-learning-engineer.json","meta":{"generated_at":"2026-10-18T13:01:01Z","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":19307,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":8004},"rest":"https://alion.io/mcp/rest/get_company?id=8004"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmarianaminerals-staff-machine-learning-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%2Fmarianaminerals-staff-machine-learning-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%2Fmarianaminerals-staff-machine-learning-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/marianaminerals-staff-machine-learning-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmarianaminerals-staff-machine-learning-engineer"}]}
