We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.\nAbout the Role\nMariana Minerals is seeking a Staff Mining Engineer with 10+ years of mining experience and a strong background in hands-on, hard-rock open pit operations. This role connects mine planning with field execution, ensuring that designs and production schedules translate into safe, practical, and efficient mining activities.\nYou will lead short- and medium-term mine planning, support daily production execution, and improve mining performance. The ideal candidate understands how a mine actually operates: equipment capabilities, achievable productivities, operational delays, and the constraints that determine whether a plan can be delivered.\nWhat You'll Do\nLead safety and uphold standards. Demonstrate visible safety leadership in the field. Incorporate operational risks, geotechnical requirements, and applicable standards into mine designs, schedules, and execution practices.\n\nDevelop mine plans and schedules. Prepare and maintain shift, daily, weekly, monthly, and rolling medium-term plans aligned with longer-term mine objectives, production targets, and available resources.\n\nTurn plans into executable operations. Translate designs and schedules into clear work instructions, priorities, and field deliverables. Confirm access, working areas, equipment, blast readiness, and material destinations with operations teams.\n\nDesign practical mining layouts. Develop and update pit, bench, ramp, haul-road, stockpile, and waste-dump designs that meet safety requirements and support efficient equipment movement and mining sequences.\n\nPlan ore and waste movement. Coordinate ore extraction, waste stripping, stockpiling, and material routing. Work with geology and processing teams to manage feed requirements, dilution, ore loss, and material tracking.\n\nOptimize drilling and blasting. Improve blast designs and sequencing to achieve safe blasting, suitable fragmentation, efficient loading and hauling, and competitive costs. Coordinate drill-and-blast readiness with the production schedule.\n\nImprove equipment productivity. Evaluate equipment capabilities, loader-truck matching, haul cycles, availability, utilization, and delays. Use realistic production assumptions and work with operations and maintenance to address constraints.\n\nMonitor execution and reconcile performance. Compare actual production with the plan, investigate variances, identify root causes, and develop practical recovery plans. Feed operating results back into planning assumptions and schedules.\n\nOptimize mining performance. Evaluate alternative designs, sequences, and operating approaches to improve productivity, reduce costs, and maintain ore supply. Use operational data and support improvements in digital planning and automation.\n\nCollaborate and develop others. Work closely with operations, maintenance, geology, survey, geotechnical, processing, and software teams. Communicate priorities clearly, share knowledge, and mentor engineers.\n\nWhat You'll Bring\nBachelor's degree in Mining Engineering.\n\n10+ years of experience in the mining industry, including substantial hands-on experience in hard-rock open pit mining operations.\n\nExpert proficiency in Deswik for mine design, mine planning, and production scheduling.\n\nStrong experience in short- and medium-term planning, operational mine design, production scheduling, and mine plan execution.\n\nDemonstrated experience in drill-and-blast optimization and ore and waste planning.\n\nStrong practical understanding of mining equipment, production rates, haulage, operational delays, and the interaction between planning, operations, and maintenance.\n\nProven safety leadership and commitment to high mining industry standards and sound engineering practice.\n\nStrong analytical, problem-solving, and communication skills, with the ability to work effectively with field crews and multidisciplinary teams.\n\nPreferred Qualifications\nExperience with heap-leach operations, leach-pad planning, stacking sequences, and coordination between mining and leaching.\n\nExperience with autonomous mining equipment, operational data systems, or automation of mine planning and production workflows.\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":4990,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Mining","Mining Tech","Non-ferrous Metals"],"lifecycle":[{"event":"open","at":"2026-10-07T19:23:59Z"}],"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":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":6,"expected_fill_days":40,"reasons":["conf:2","stale_co","velocity","win:early"],"computed_at":"2026-10-14T06:34:16Z"},"pay":{"stated_usd_annual":171000,"is_top_pay":false},"html_url":"https://alion.io/job/mariana-minerals-staff-mining-engineer","json_url":"https://alion.io/job/mariana-minerals-staff-mining-engineer.json","meta":{"generated_at":"2026-10-14T15:35:55Z","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":19734,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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-staff-mining-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-staff-mining-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-staff-mining-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-staff-mining-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmariana-minerals-staff-mining-engineer"}]}
