Overview

AfterQuery supplies expert data to top AI labs, and this contract role puts your plant-floor knowledge to work building problems that test and train machine learning models. The engineers they want are the ones who have reconciled real plant and pilot data against design specs, whether that means column, reactor, membrane or utility performance figures, or guarantee test results. You write in Python against your own datasets, then turn that material into research-grade problems with clear documentation. Work happens on your schedule, task by task, with no required weekly hours.

What You'll Do6

Compose research-level problems drawn from your own chemical and process plant experience
Work from real plant or pilot datasets, including performance and guarantee test records
Document each task so another technical reader can follow your reasoning and data handling
Set your own hours and pace across as many approved tasks as you choose to take
Check your submissions for accuracy before handing them off
Use Python to process and examine the plant data behind each problem you write

Requirements4

Direct experience analyzing your own real plant or pilot data in Python or a comparable language
Ability to explain technical work in your field through clear writing
Comfort working without supervision and setting your own schedule
Background with real operating data rather than process simulation alone

Preferred Qualifications4

3+ years in operating or pilot plants plus a degree in chemical engineering
Experience running performance or guarantee tests, data reconciliation, and troubleshooting reports on live plant data
Public code, a thesis, or published papers that demonstrate your technical work
Previous work in data annotation, labeling, or AI/ML evaluation

Who Should Apply

Process and chemical engineers who have spent years in operating or pilot plants and can point to real datasets they handled themselves. A chemical engineering degree and Python fluency matter more than simulation-only design work here.

Salary Insight

Each approved task pays $300 and typically takes about 6 hours, which works out to roughly $50 per hour. You can accept as many tasks as you like, so earnings scale with the time you commit. Accepted experts complete standard background and identity verification.
