On November 2, 2026 our feed held 91 live listings that name Brazil, from 8 platforms. Most of them are not what the number suggests: 58 are SME Careers talent-pool listings that publish a ceiling and no floor, so the rest of the picture is 33 listings from seven platforms. Every number below comes from the listings, and every rate is in US dollars. You do not need Portuguese for most of them.

How the 91 break down

SME Careers has 58, Meridial 8, Anyone AI 8, Mindrift 7, Welo Data 5, Mercor 3, and Alignerr and Rex one each. These are the listings that name Brazil. More than 2,000 other listings in our feed state no country restriction, and are open to someone in Brazil too. Our Brazil page lists the ones that name the country.

The kinds of work

Software engineering and STEM, in English

Anyone AI's eight listings are all titled for Brazil. Four are developer roles (Full-Stack, Backend, Python, and a Software Engineering AI Trainer) that state $45 to $80 an hour. The text says consultants are paid on a per-project basis and that the hourly rates are estimates based on anticipated completion time. They ask for 2 to 7 years of professional engineering experience and advanced written English, not Portuguese. Three more are STEM roles (Mathematics, Biology and Physics) at up to $40 an hour, for about 20 hours a week (20 to 40 for physics) over two months with a possible extension. The eighth is a Quality Evaluator role for fluent English speakers at $7 to $12 an hour, for up to three months.

SME Careers has 16 programming-language engineer roles (Python, Rust, SQL, TypeScript, C and others), 5 other engineering roles, and professional roles such as Dentist, Radiologist, Attorney and Accountant. The highest ceilings are Medical Doctor (Specialist) at up to $150 an hour, and Radiologist and Attorney and Lawyer at up to $120.

Portuguese language work

Meridial has 8 Brazil listings: a Portuguese Language Specialist, a Language Alignment and Resource Partner, Paulistano and Carioca dialect specialists, and four subject specialists fluent in Portuguese (Mathematics, Science, STEM and Coding). They state $6 or $8 up to $65 an hour, with the exact rate set after evaluating your experience, expertise and geographic location. SME Careers adds a Portuguese Language Expert and a Portuguese Quality Assurance Lead. Welo Data lists a Junior Quality Coordinator for its Portuguese (Brazil) search quality project, with no pay stated, and a Session Director for a Portuguese (BR) voice recording project at $50 an hour. For the language side in full, see our Portuguese speakers guide.

One-off studies, ratings and the rest

Mercor has a paid research study at $100 flat for a roughly 20-minute survey, for people in Brazil with financial ties to the United States, and a paid expert interview for software engineers at $100 to $120 for 45 to 60 minutes. Its third listing is a Customer Success Engineer at $35,000 to $50,000 a year, open only to people residing in Latin America. Welo Data's Ads Quality Raters (German and Italian, $7 and $6.50 an hour) require you to review ads in English and that language, and to live in Brazil. Mindrift has 7 listings for Latin America (3 physician roles and 4 CAD and CFD engineering roles) with no description and no pay in the feed. Alignerr has one Economics Teacher listing with neither, and Rex has a Generalist AI Trainer role open in 34 countries with pay described as market-range, based on experience, location and workload.

The catches

Common questions

Do I need to speak Portuguese?

Not for most of them. Anyone AI's developer, STEM and evaluator roles ask for English, and SME Careers lists mostly English-language professional and engineering roles. Portuguese is the requirement for Meridial's language roles, Welo Data's Portuguese listings and two SME Careers roles.

Do I need to live in Brazil?

For the listings that name Brazil, yes. Welo Data says that even though the position is work from home you must reside in the country noted, and Mercor's Customer Success role is for residents of Latin America.

Which platform should I try first?

For a stated hourly figure and a defined project, Anyone AI. For breadth and language work, Meridial. Compare the platforms on the pay report.
