Process & Chemical Plant Engineer

Use your hands-on experience in chemical engineering to write research-level problems for AI models. Remote, flexible contract work. AfterQuery works with leading AI labs to build the expert data that tests and trains AI models. We're looking for process and chemical plant engineers who work with real plant and pilot data: the plant and pilot data you reconcile against design, from column, reactor, membrane and utility performance to guarantee tests. Requirements Technical: Working knowledge of Python for working with your own plant data. Work authorization: Must be able to work as an independent contractor without visa sponsorship. Students on F-1 visas (including OPT/CPT) are not eligible. Preferred Background: 3 or more years in operating plants or pilot plants, with a Bachelor's, Master's or PhD in chemical engineering. Hands-on work with real data, rather than pure process-simulation design (Aspen or HYSYS). Contract and pay Flexible, independent-contractor work: $300 per approved task, about 6 hours each (roughly $50 per hour), with no cap on how many tasks you take on. All accepted experts undergo standard background and identity verification.
