Physics Specialist - Freelance AI Trainer Project

3 to 6 weeks, considerably longer than most AI training platforms. You'll go through a detailed application, multi-stage logic and writing assessments, a video interview (async or live), and then a formal offer letter with onboarding instructions. Meridial is the specialized AI training division of Invisible Technologies, so it runs closer to a professional hiring pipeline than a gig-app signup.

Complex, high-context reasoning rather than quick micro-tasks: multi-step problem-solving, detailed content evaluation, and strict style-guide adherence. Individual tasks commonly run 15-30 minutes, versus the 5-minute tasks typical on other platforms, so expect fewer, deeper assignments rather than a high-volume queue.

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.

Most skip a live interview entirely and gate access through an automated assessment or qualification task instead. Where we've confirmed the specific requirement for this listing, it's called out above in What We Know About This Role.

Tasks here are scoped to STEM, not generic labeling. As a Physics Specialist - Freelance AI Trainer Project, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to STEM) rather than following a one-size-fits-all rubric. If you don't have hands-on STEM background, this is likely not the right listing to start with.

AI Training is named directly in the listing. If you don't have hands-on experience with this, expect the screening process to test for it directly rather than accepting adjacent experience as a substitute.

This listing is posted at $8–$65/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.

This specific role is open only to people based in United States of America. 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.
