The idea is simple
Better AI starts
with human expertise.
AI learns from examples and feedback. It needs people who know their subject to show it what’s accurate, useful and worth improving.
Our mission is to make that work easier to find - connecting what you know with opportunities to put it to use.

A few things to know
Before you begin.
Straight answers to the questions
you might be asking.
Many roles need knowledge of a subject rather than experience building AI. Some ask for a degree, professional experience or particular tools. Each listing explains the requirements.
Opportunities span engineering, science, medicine, law, finance, languages and more. The available fields and projects change, so check the current listings for work that fits your background.
The hiring partner manages the project, contract and payments. Tier1 helps you discover and compare opportunities and begin your application. The partner confirms the final terms and available work.
Rates vary by role, expertise and project. We display the published rate and pay period so you can compare opportunities before applying. Earnings depend on the work available and the terms agreed with the hiring partner.
Some projects have flexible hours; others require a regular weekly commitment. Check each role’s hours, location requirements and contract terms to see whether it suits your schedule.
