Chemical Engineer - AI Trainer (Remote)
Apply NowFully remote. Open to candidates anywhere in the United States. Independent contract, $100-$130/hour, fully async with no fixed hours.
Chemical engineers to build the process design and safety scenarios frontier AI labs use to test model judgment. Remote, async, paid weekly.
AfterQuery builds the expert evaluation data that frontier AI labs use to measure and improve their models. We're hiring chemical engineers as contractors to author and grade the process design and safety scenarios those evaluations run on.
What you'll actually do
- Author realistic process scenarios, from mass balances through safety review
- Write reference answers with the process and safety reasoning behind each decision
- Grade model output for technical accuracy and process safety
- Flag designs that read plausible but would be unsafe or infeasible at scale
Who this is for
- Engineers with a degree in chemical engineering or a closely related field
- Practitioners with at least 2 years of process, plant, or product engineering experience
- Engineers with depth in process design, process safety, or scale up
- Clear writers who can document the reasoning behind a process decision
