Mechanical Engineers (Automotive and Aerospace): Project on Change Workflows

Yes. Terac is a funded, US-based marketplace with real AI-lab and market-research clients, not a task-mill. It verifies your identity and professional background before matching you to any paid work, which is stricter screening than most open task queues use.

You complete a short AI-driven interview, identity verification, and a domain-specific screening test once. After that, Terac matches verified candidates to paid studies that fit their profile instead of running an open queue, and pay is released once your submission on this listing is checked against the requirements above.

Project-based, not steady. Terac opens listings like this in bursts when an AI lab requests a specific batch, categorizing data, writing or validating coding tasks, creating expert-level problems, and closes them once the batch is filled or complete. Treat it as recurring gig income you requalify for each time, not a standing job.

Pay tracks verified expertise, not a platform-wide rate. Generalist labeling sits at a few dollars an hour; work gated behind a passed domain screening, like software engineering or STEM problem creation, pays task bounties well over $100. Check this listing's own rate above rather than assuming other Terac listings pay the same.

No. Instead of client deliverables, you're given complex scenarios to evaluate: grading the AI's logic, correcting its hallucinations, and supplying expert-level reasoning it doesn't have on its own. The job is closer to teaching than consulting.

Because general knowledge isn't what's being tested. The model already knows the basics; what it needs is expertise on edge cases, the rare, difficult, highly technical judgment calls only a senior professional in the field would make correctly.

Slow and deep, not fast and repetitive. A single task can take 45-60 minutes of researching citations or verifying complex calculations. Quality is what's being measured here, not throughput.

Tasks here are scoped to STEM, not generic labeling. As a Mechanical Engineers (Automotive and Aerospace): Project on Change Workflows, 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.

You'll be taken to Terac'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 restricted to USA. If you are outside these locations, applying is unlikely to result in an offer even if you pass the assessment. Check the full job description for any VPN or tax-residency caveats.
