Build AI-native intelligence systems behind Replit's hiring, comp, and workforce decisions

Replit is hiring a Data Scientist, People to move beyond dashboards and build predictive models and AI agents that directly recommend compensation adjustments, flag attrition risk, and inform hiring and org-design decisions. The role requires strong SQL/Python, causal inference and experimentation depth, and hands-on use of LLMs on unstructured People data (exit interviews, performance reviews). Expect the interview to test statistical rigor, applied AI-agent design for high-stakes decisions, and comfort handling sensitive compensation/org data.
