Chemical Engineer Expert

Pay: $115/hour

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

Contract and pay

• $100 to $130/hr, paid weekly via Stripe. Your rate is set from your experience, not negotiated down after you start.
• Fully remote, fully async. No fixed hours.
• Minimum 10 hours per week, no maximum. Scale up or down week to week.
• No screen recording, no keystroke monitoring, no idle timers.
• Independent contractor. Ongoing project work rather than single task batches.
