xAI is hiring a software engineer for its evals team, which builds instruments that measure model capabilities and behavior, cleans datasets, grades outputs, and diagnoses why agents fail. The work covers execution infrastructure, dataset and grading-scheme design, and internal tools that engineers use daily. The posting asks for 3+ years writing code, a record of shipping, and product judgment for turning notions like helpfulness, truthfulness and safety into measurable criteria. Levels run from new grad to senior; it is on-site in Palo Alto.
