We operate in 35 countries where we produce iron ore, copper, aluminium, critical minerals, and other materials needed for the global energy transition and for people, communities, and nations to thrive.\nWe have been mining for 150 years and operate with knowledge built up across generations and continents. Our purpose is finding better ways to provide the materials the world needs - striving for innovation and continuous improvement to produce materials with low emissions and to the right environmental, social and governance standards. But we can’t do it on our own, so we’re focused on creating partnerships to solve problems, create win-win situations and meet opportunities.\nWhere you will be working\nRecognized as a pioneer and leader in the industrial minerals industry due to product quality, supply reliability and technical support; we are proud to make modern life work. Lithium is part of our portfolio of materials essential to a low-carbon future and is a key element needed for low-carbon technologies. The Battery Materials unit is comprised of the Borates operations in US, the Jadar Project in Serbia and the Rincon project in Argentina, leading in mining borates and lithium for a more sustainable future. The Rincon lithium project is a large undeveloped lithium brine project located in the heart of the lithium triangle in the Salta Province of Argentina, an emerging hub for greenfield projects. It is a long-life, scalable resource with one of the lowest carbon footprints of lithium assets in the world. This acquisition is a significant further endorsement of our commitment to the battery materials sector and lithium's role in a low-carbon future.\nRespect and Inclusion\nAt Rio Tinto, we particularly welcome and encourage applications from Indigenous Peoples, women, the LGBTQ+ community, mature workers, people with disabilities, and people from different cultural backgrounds. We are committed to an inclusive environment where people feel comfortable being themselves. We want our people to feel that all voices are heard, all cultures respected and that a variety of perspectives are not only welcome - they are essential to our success. We treat each other fairly and with dignity regardless of race, gender, nationality, ethnic origin, religion, age, sexual orientation, or anything else that makes us different.","description_format":"text","description_chars":7454,"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":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Argentina","iso":"AR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Mining","Iron Ore","Non-ferrous Metals"],"lifecycle":[{"event":"open","at":"2026-10-30T21:37:57Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.9,"p_room":1,"age_days":5,"expected_fill_days":17,"reasons":["conf:3","velocity","win:early","comp:brand"],"computed_at":"2026-11-05T05:54:30Z"},"pay":null,"html_url":"https://alion.io/job/rio-tinto-asesora-de-contabilidad-de-proyectos","json_url":"https://alion.io/job/rio-tinto-asesora-de-contabilidad-de-proyectos.json","meta":{"generated_at":"2026-11-05T15:25:26Z","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":20204,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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":183},"rest":"https://alion.io/mcp/rest/get_company?id=183"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frio-tinto-asesora-de-contabilidad-de-proyectos"},{"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%2Frio-tinto-asesora-de-contabilidad-de-proyectos"},{"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%2Frio-tinto-asesora-de-contabilidad-de-proyectos"},{"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/rio-tinto-asesora-de-contabilidad-de-proyectos\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frio-tinto-asesora-de-contabilidad-de-proyectos"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3548342}},{"tool":"search_jobs","arguments":{"company":"riotinto.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3548342},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
