Materials Science and Engineering Expert

Materials scientists and engineers to build the selection and failure analysis scenarios frontier AI labs use to test model judgment. AfterQuery builds the expert evaluation data that frontier AI labs use to measure and improve their models. We're hiring materials scientists and engineers as contractors to author and grade the selection and failure analysis scenarios those evaluations run on. What you'll actually do Author realistic materials scenarios, from selection through failure analysisWrite reference answers with the structure property reasoning behind each decisionGrade model output for technical accuracy and practical feasibilityFlag recommendations that read plausible but would fail in service Who this is for Scientists and engineers with a degree in materials science and engineering or a closely related fieldPractitioners with at least 2 years of professional materials engineering or R&D experienceSpecialists with depth in at least one materials class such as metals, polymers, ceramics, or semiconductorsClear writers who can document the reasoning behind a materials decision Contract and pay $100 to $130/hr, paid weekly via Stripe.

About AfterQuery AfterQuery is an expert data lab. We build the evaluation and training data that frontier AI labs use to measure what their models can and can't do in real professional work. Our contributors are practicing professionals, not annotators, and the work is credited, reviewed, and paid at professional rates.
