AI Red-Teamer — Adversarial AI Testing (Advanced); English & Brazilian Portuguese

Mercor places you with one client for a defined engagement, like 'Python Tutor for 3 months', rather than having you grab small tasks from a shared queue. Most roles function as steady contract work, not one-off gigs.

Yes, every applicant records a video interview with an AI interviewer that asks questions about your resume. Clients review that recording to judge communication skills before matching, so there's no way to apply without going on camera.

No set hours, no check-ins, no meetings. You log in when you want, pick up an available task, complete it, and submit; nobody is waiting on you in real time. That's different from remote employment, where you're expected online during business hours. The tradeoff: you're competing with others for available tasks, so an empty queue means there's simply nothing to do until more work is released.

Tasks here are scoped to Software Engineering, not generic labeling. As an AI Red-Teamer — Adversarial AI Testing (Advanced); English & Brazilian Portuguese, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Software Engineering) rather than following a one-size-fits-all rubric. If you don't have hands-on Software Engineering background, this is likely not the right listing to start with.

Brazilian Portuguese, English, and Portuguese are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.

This listing is posted at $28–$74/hr, an hourly rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

Yes. This role specifically requires Brazilian Portuguese, English, or Portuguese proficiency, on top of the English most AI training work assumes by default. If Brazilian Portuguese is not a language you're fluent in, this is not the right role. Filter for your native language to find better-matched listings.

You'll be taken to Mercor's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

This specific role is open only to people based in Brazil and the United States. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply, since they can differ by country.

Not immediately. Mercor is a talent marketplace, not a task queue, so applying puts you in a pool of candidates. You start working only once a specific client, like a major AI lab, selects your profile, and that matching process can take weeks.
