Process and materials work for AI
AI Training Jobs for Chemical Engineers
Measured from 13 distinct advertised rates, across 5 platforms. 6 of the 31 open roles here state no hourly rate; 12 advertise only a maximum ("up to $X/hr"), which is excluded.
AI labs pay chemical engineers and materials scientists by the hour to grade a model's process, materials and safety reasoning, and to write the engineering problems it is tested on. 31 roles for chemical engineers and materials scientists are open right now on 8 platforms, including SuperAnnotate (SME), AfterQuery and Mercor. Every role is checked against its platform's job board daily.

Before you apply
This is training and evaluation work for AI models, not engineering you sign off. If you work for an employer, check its policy on outside work first, and never bring proprietary processes, formulations or plant data into a task. A legitimate platform never charges you to apply.
Pay by specialty
Each specialty's typical pay is measured over its own open roles the way every band on this site is (the 25th percentile of what roles pay (the middle of each advertised range) to the 90th-percentile advertised ceiling), and shown only where at least three distinct rates are posted.
| Specialty | Open roles | Typical pay | Highest rate |
|---|---|---|---|
| Nuclear engineers | 3 | Too few rates | $65/hr |
| Materials scientists | 18 | $80–$125/hr | $175/hr |
| Chemical and process engineers | 10 | $55–$105/hr | $115/hr |
What the roles ask for
Read from the requirements of 22 of the 31 open roles for chemical engineers and materials scientists: the lines each role's pop-up lists from its posting. A role counts once, at the lowest degree it accepts.
The roles that name experience ask for a median of 3 years.
What platforms pay to find you
AfterQuery and Turing post a flat referral bonus on 5 of the 31 open roles for chemical engineers and materials scientists: what the platform pays whoever refers the person it accepts, a measure of how hard these people are to find. The platform pays it, and it never comes out of your pay.
| Role | Platform | Referral bonus |
|---|---|---|
| Chemical Engineer Expert | AfterQuery | $550 |
| Materials Science and Engineering Expert | AfterQuery | $530 |
| Computational Materials Science Expert | AfterQuery | $380 |
| Computational Materials Science Researcher (Task Author) | AfterQuery | $100 |

Frequently asked questions
How much do AI training jobs for chemical engineers and materials scientists pay?
Across the 13 distinct hourly rates posted for roles for chemical engineers and materials scientists right now, typical pay runs from $65 to $115 an hour, with a median of $80. The highest posted rate is $175 an hour, at AfterQuery. 6 of the 31 open roles for chemical engineers and materials scientists state no hourly rate, so check each listing.
Do I need a graduate degree or a license?
Most roles ask for a degree in chemical engineering or materials science and practical experience; the research roles ask for a master's or PhD. Each listing states what it requires and where it is open. Of the 22 open roles for chemical engineers and materials scientists whose requirements we read, 2 ask for a PhD, 5 a master's, 13 a bachelor's or a degree and 2 name no degree.
What does a chemical engineer or materials scientist do in AI training?
You write problems from your field with verified solutions, grade a model's calculations, process designs and materials reasoning, and correct what would fail in a plant or a lab. It is remote, hourly contract work.
How do platforms check chemical engineers and materials scientists?
Most platforms start with an assessment in your field before any paid work, and each listing says what it asks for. Of the platforms hiring chemical engineers and materials scientists now, SuperAnnotate (SME), Mercor, Turing, Alignerr and Sovrano AI run an AI interview (a recorded interview scored by AI) for many roles. SuperAnnotate (SME), AfterQuery, Turing, Alignerr and Handshake AI check a government photo ID, usually with a selfie, before you are paid. AfterQuery and Turing say they check credentials such as degrees. The section on how each platform checks you quotes each guide with its source.
Are these jobs legitimate?
They are posted by established AI data platforms (SuperAnnotate (SME), AfterQuery, Mercor and Turing among them), and each platform's page here covers whether it is legit, how it vets people and how it pays. A legitimate platform never charges you to apply or to get work.
