About Hire Feed
HireFeed: A QuikHire product.
Earn in dollars. On your hours. From wherever.
HireFeed is the AI-curated feed of contract, gig, and AI training jobs that pay in USD, built for the people who actually want to work, not the ones writing job descriptions.
Why it exists: the highest-paying contract work in the world - RLHF, AI evaluation, domain-expert training, senior contract engineering, sits scattered across hundreds of ATS feeds and platform job boards. Most of it never makes it to Indeed or LinkedIn, and the roles that do are usually stale by the time you find them. The best opportunities are also the most ephemeral.
HireFeed pulls from 500+ verified sources, including Outlier, Mercor, Surge AI, Micro1, Turing, Toloka, Appen, and Remotasks, and refreshes every 60 seconds. The moment a role closes at the source, it falls off the feed.
What you'll find here:
- AI training, RLHF, and evaluation: $20–$80/hr
- Domain experts: medical, legal, finance, math (PhD)
- Senior contract engineering, paid weekly
- Multilingual annotation, creative writing training, AI research
What you won't find: pay-undisclosed listings, expired roles, "still accepting applications" lies, recruiter middlemen, or data resale. Pay is a hard requirement. Apply links 302-redirect to the source ATS. We never see your résumé.
Free for candidates, forever. Funded by the partner side.
