Overview Handshake is seeking postdoctoral researchers and Math PhDs to support AI research through flexible, hourly contract work. This is not a traditional academic or full-time role. You'll use your advanced mathematical training to evaluate AI-generated content and provide feedback that helps AI better understand mathematical reasoning, proof construction, and technical problem-solving. This is an ongoing, project-based opportunity that can be done alongside research, teaching, postdoctoral work, or industry employment.
