We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.\nWe’re building a core commissioning team of talented, versatile engineers who know how to take a plant from mechanical completion to running. As a Commissioning Engineer, you’ll own electrical and mechanical commissioning scopes: energizing power systems, bringing up equipment and utilities, and getting new systems online safely.\nYou’ll work alongside local commissioning teams, own your commissioning assignments, and make sure we’re building and using our systems throughout commissioning.\nYour first year will likely be focused on Copper One, our operating copper mine and refinery in Utah, or Lithium One, our new lithium facility in Texas. After that, you’ll go wherever we’re bringing new capacity online, anywhere in the world. Between commissioning pushes, you’ll support design teams and projects at other sites. There’s always something being built.\nThis is a hands-on role for scrappy, collaborative engineers who thrive during startup. You’ll solve problems in the field, do some of your own design work when needed, bring new systems online for the first time, and do it safely, every time.\nResponsibilities\nLead commissioning teams at various locations. The candidate must be willing to travel to sites during commissioning.\n\nDevelop detailed commissioning plans in advance of commissioning activities.\n\nEnsure documentation is complete, including LOTO procedures, work instructions, maintenance procedures, detailed plans, schedules, budgets, etc.\n\nOwn scopes relative to engineering expertise.\n\nLead safe startup practices so everyone gets home safe.\n\nConfirm proper installation and functionality of equipment. Lead specific activities on site during dry and wet commissioning.\n\nLead ramping activities for assigned commissioning area(s).\n\nEnsure equipment is functional, including controls functionality.\n\nTrain and hand over equipment to onsite operators and maintenance personnel.\n\nServe as a technical expert to assist in process engineering after handover to operations as needed.\n\nSimplify commissioning procedures, then assist in building tools in MarianaOS to automate and scale.\n\nDocument and share lessons learned so every site starts from a stronger playbook.\n\nSupport design teams and projects at other sites between commissioning cycles.\n\nContribute to design reviews and HazOps during the design phase.\n\nTravel up to 80%, including extended site assignments during onsite commissioning. Short-notice trips are possible. Between projects, work from a Mariana office or, preferably, an operating asset when needed.\n\nRequirements\nBachelor’s degree or higher in chemical, mechanical, electrical, or a related engineering field preferred, or proven hands-on experience commissioning industrial systems.\n\nHands-on commissioning experience on greenfield or new-plant startups, with deep expertise in electrical or mechanical systems and working knowledge of the other.\n\nBackground in battery/EV, semiconductor, data centers, advanced manufacturing, or similar fast-paced industrial environments strongly preferred.\n\nWorking knowledge of equipment common in mining and/or refining and plant utilities.\n\nAbility to read and mark up single-lines, P&IDs, schematics, and mechanical drawings.\n\nDesire to help build a smart P&ID system.\n\nPreferred: PLC/controls and instrumentation startup experience, experience at a company that designs, installs, and commissions its own equipment, and comfort using AI tools to speed up your work.\n\nCollaborative by default. You share knowledge openly and make the team around you better.\n\nStrong safety mindset, with experience leading safe energization, LOTO, and startup practices (NFPA 70E).\n\nValid driver’s license.\n\nSafety\nSafety comes first on every project. You’ll model our site safety policies every day and help lead safe startup practices on site.\nLead JHAs and LOTO for your commissioning scope, follow permit-to-work procedures, and participate in safety meetings, audits, and incident investigations.\n\nParticipate in HazOps.\n\nAlways wear proper PPE and complete all site safety training.\n\nPhysical Demands & Work Conditions\nExpect heavy on-site work, and extended or irregular hours during commissioning, followed by stretches of remote or office-based work.\n\nActive industrial and construction environments that involve standing, walking, climbing, and working in tight spaces for extended periods, and lifting up to 50 lbs.\n\nNoise, dust, outdoor work in varying weather, and remote site locations.\n\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":5316,"description_truncated":false,"requirements":{"experience_years_min":null,"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":["Mining","Mining Tech","Non-ferrous Metals"],"lifecycle":[{"event":"open","at":"2026-10-15T03:34:09Z"},{"event":"close","at":"2026-10-22T04:46:42Z"}],"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":0}],"liveness":null,"pay":null,"html_url":"https://alion.io/job/mariana-minerals-commissioning-engineer","json_url":"https://alion.io/job/mariana-minerals-commissioning-engineer.json","meta":{"generated_at":"2026-10-25T07:45:38Z","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":10905,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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%2Fmariana-minerals-commissioning-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%2Fmariana-minerals-commissioning-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%2Fmariana-minerals-commissioning-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/mariana-minerals-commissioning-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmariana-minerals-commissioning-engineer"}]}
