Paid expert work, rates exactly as published.
Your profile
One profile, and the board only shows what you can take.
Of 843 open roles, some are limited to one country and some need a language you may not have. Three questions is enough to tell them apart - and to stop you reading roles you could never accept.
Join Tier1About two minutes - your CV does most of it
Your CV is read once to build your profile and is never stored. The profile it builds is yours: it sits in your account, readable by you and nobody else, and is never sent to a provider - you apply on their site, as always.
Pick the fields you have worked in
Medicine, law, finance, software - whatever you already do for a living. No AI experience required, and none is asked for.
Say where you are and what you speak
This is what actually decides eligibility: some roles are open to one country, some need a specific language.
See only the roles that are open to you
Every row then tells you whether you qualify, and why - no score, no guessing, no applications into a wall.
How this is paid for. Applying is free and always will be. When a project hires you through a link here, the platform running that hire pays us a referral fee from their own budget - your rate is not touched, and no role is placed higher because of it.
Questions
Everything people ask before their first application.
AI labs need people who already know a subject to write, review and grade the material their models learn from. A radiologist checks how a model reads a scan. A tax lawyer writes the problem it keeps getting wrong. A linguist records the way a sentence is really said. You are paid for your judgement, not for your typing.
No. Nearly every role here asks about your profession and nothing about AI - that is the point of hiring you. Where a role does need a specific tool, language or degree, it says so, and the role page lists it.
Most roles pay by the hour with the rate published up front: the median on the board right now is $70 an hour and the highest is $400. Some pay per task or per project instead. You are paid by the platform you sign with, on their schedule - never through us.
Work modes and location requirements vary by role. 13% of roles explicitly list worldwide availability. The country filter removes known restrictions; where the location is not specified, check the offer before applying.
Select Apply, create an account or log in, and add your CV. Your selected offer opens in your dashboard. Partner offers continue on the partner site; direct offers accept your application in Tier1. We may earn a referral fee from a partner. You are never charged to apply, and no role is ranked higher because of a referral fee.
Every source is re-read every few hours, and a role appears here only while it is still open at that source. 843 roles are live right now. When one closes it leaves the board, which is why the count moves during the day.
