We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.\nRole Overview\nWe are hiring a Mechatronics Engineer (Hardware) to design and build the actuation, automation, and robotic hardware that makes our autonomous mining vehicles move.\nIn this role you will own the electromechanical and robotics hardware that enables full mining autonomy - drive-by-wire actuation, motion and powertrain systems, robotic mechanisms, and the automation hardware that ties them together. You will carry designs from concept and trade study through CAD, analysis, prototype build, and bench and field validation, working hand in hand with our controls, autonomy software, and systems-engineering teams. This is a hands-on, first-principles role for an engineer who wants to develop the world’s first fully autonomous mines.\nWhat You’ll Do\nDesign and integrate actuation hardware for autonomous mining vehicles - drive-by-wire steering, braking, and throttle, electric and electrohydraulic actuators, and the motion and powertrain systems that drive the vehicle\n\nDevelop robotic mechanisms and automation hardware (manipulators, end-effectors, automated tooling, and material-handling systems) for unmanned mine operations\n\nProduce detailed CAD models, drawings, tolerance stack-ups, and bills of materials ready for fabrication, procurement, and assembly\n\nSelect, size, and qualify actuators, drives, motors, gearboxes, bearings, and e-powertrain components, balancing build-vs-buy decisions against cost, lead time, and reliability\n\nLead subsystem bench and rig testing, build and instrument prototypes, and drive reliability growth against MTBF and availability targets\n\nCollaborate with controls and autonomy-software engineers to integrate actuation, compute, and sensing into a complete vehicle\n\nWhat You’ll Bring\nBachelor's degree in Mechatronics, Mechanical, Robotics, Electrical, or related engineering discipline\n\n5-10+ years designing complex electromechanical or robotic systems, ideally including mobile or heavy equipment\n\nStrong proficiency with 3D CAD\n\nHands-on experience with actuation and motion systems - drive-by-wire, electric or electrohydraulic actuators, motors, drives, gearboxes, and their integration\n\nWorking knowledge of design-for-manufacture/assembly and of component selection, qualification, and supplier engagement\n\nExperience in autonomous vehicles, robotics, automotive, or off-highway equipment strongly preferred\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":3220,"description_truncated":false,"requirements":{"experience_years_min":5,"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":"2026-06-26T16:30:57Z"}],"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":7}],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.444,"p_room":0.28,"age_days":121,"expected_fill_days":40,"reasons":["conf:2","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-26T05:57:25Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":false},"html_url":"https://alion.io/job/marianaminerals-mechatronics-engineer-hardware","json_url":"https://alion.io/job/marianaminerals-mechatronics-engineer-hardware.json","meta":{"generated_at":"2026-10-26T16:24:14Z","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":21846,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"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-mechatronics-engineer-hardware"},{"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-mechatronics-engineer-hardware"},{"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-mechatronics-engineer-hardware"},{"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-mechatronics-engineer-hardware\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmarianaminerals-mechatronics-engineer-hardware"}]}
