Every listing links straight to the employer, so you apply on their own board rather than through an intermediary."},{"title":"What these roles pay","text":"Most employers in this selection do not publish a figure, so the range below is Alion's own estimate, derived from 38 comparable listings priced by role, level and country. Across them the middle half of the market sits between $84K and $107K a year, with a median of $92K. By level, the median runs senior at $85K, staff at $113K, and lead at $105K. The step from senior to lead is worth about 1.2x on median pay. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable."},{"title":"Where the work is","text":"The largest concentrations of these roles are Argentina (67), Colombia (4), Mexico (4), Spain (4), and Peru (3). 22% of the listings are fully remote and a further 31% are hybrid, so a large part of this market is open to you regardless of where you live."},{"title":"Who is hiring","text":"The employers with the most open Machine Learning Engineer jobs in Buenos Aires right now are Accenture (4), EY (3), JPMorganChase (3), NTT DATA (3), Darwin AI (3), and Profound (3). Each company page on Alion carries its size, funding stage, tech stack and every other position it has open, so you can judge the employer before you spend an evening on the application."},{"title":"What employers ask for","text":"Reading across the current listings, the tools that come up most often are Python (49), AI Agents (29), AWS (25), RAG (21), GCP (20), LLM (19), Machine Learning (19), and JavaScript (18). The counts are how many of these openings name each one, which is a better guide to what is actually being hired for than a generic skills list."},{"title":"Relocation, visas and equity","text":"Of the current Machine Learning Engineer jobs in Buenos Aires, 4 state visa sponsorship and 1 includes equity. These are filters on the list above, so you can narrow it to the ones that make a move possible for you."}],"faq":[{"question":"How many Machine Learning Engineer jobs in Buenos Aires are open right now?","answer":"There are 67 open Machine Learning Engineer jobs in Buenos Aires on Alion from 44 companies. The list was last refreshed on October 23, 2026."},{"question":"Are all of these Machine Learning Engineer jobs in Buenos Aires still being filled?","answer":"Probably not all of them. 6 of the 67 show the marks Alion reads as a likely inactive posting: open far longer than employers usually take to fill such a role, reposted several times, or sitting on a board that rarely closes anything. They stay listed with a warning, and the list can hide them with one switch."},{"question":"What do Machine Learning Engineer jobs in Buenos Aires pay?","answer":"The median is $92K a year, and the middle half of the market falls between $84K and $107K. Few of these employers publish a figure, so this is Alion's estimate based on 38 comparable listings."},{"question":"Are any of these roles remote?","answer":"15 of the 67 listings (22%) are fully remote, and you can filter the list down to them in one click."},{"question":"Which companies are hiring?","answer":"The most active employers right now are Accenture, EY, JPMorganChase, NTT DATA, Darwin AI, and Profound. Each has its own page on Alion with the rest of its open roles."},{"question":"Can I get visa sponsorship or relocation?","answer":"Yes - of the current listings, 4 state visa sponsorship. Both are filters on the jobs page."},{"question":"How do I apply?","answer":"Open any listing and apply on the employer's own board through the link on the page. No account is required to browse or to apply."}]},"jobs":[{"id":3182268,"url":"https://alion.io/job/software-para-restaurantes-bares-y-cafes-gtm-ai-data-specialist","json_url":"https://alion.io/job/software-para-restaurantes-bares-y-cafes-gtm-ai-data-specialist.json","title":"GTM AI & Data Specialist","company":{"id":2159551,"name":"Software para restaurantes, bares y cafés.","url":"https://alion.io/company/fu-do"},"work_mode":"on_site","salary":null,"status":"live","updated_at":"2026-10-23T21:57:05+00:00"},{"id":3007896,"url":"https://alion.io/job/launch-potato-staff-applied-scientist-adtech-17","json_url":"https://alion.io/job/launch-potato-staff-applied-scientist-adtech-17.json","title":"Staff Applied Scientist, AdTech","company":{"id":69,"name":"Launch Potato","url":"https://alion.io/company/launch-potato"},"work_mode":"remote","salary":null,"status":"live","updated_at":"2026-10-21T13:16:08+00:00"},{"id":2934124,"url":"https://alion.io/job/allshore-talent-forward-deployed-engineer-creative-ai-100-remote","json_url":"https://alion.io/job/allshore-talent-forward-deployed-engineer-creative-ai-100-remote.json","title":"Forward Deployed Engineer – Creative AI (100% Remote)","company":{"id":669749,"name":"AllShore Talent","url":"https://alion.io/company/allshoretalent"},"work_mode":"remote","salary":null,"status":"live","updated_at":"2026-10-20T12:50:00+00:00"},{"id":2896440,"url":"https://alion.io/job/ey-ai-developer-senior-ey-gds","json_url":"https://alion.io/job/ey-ai-developer-senior-ey-gds.json","title":"AI Developer -
