Help train and evaluate AI agents on expert-level fluid simulation tasks. You will work with CAD geometry, set up and run simulations, build verified reference solutions, and write Python checks for agent results. This is a freelance opportunity, fully remote and performed on your own schedule. During active project phases, tasks are estimated to require around 10–20 hours per week; this is not a guaranteed workload. Contributors can earn up to $9 per hour equivalent, depending on their level and pace of contribution. Compensation varies by project scope, complexity, and required expertise. Performance-based bonus programs reward high-quality work and consistent delivery.
