About the Role
An HR Generalist in Chicago is a cross-functional people operations professional who manages employee relations, benefits administration, onboarding, payroll coordination, and policy compliance. On Rex.zone, many employers operate AI/ML training pipelines—such as RLHF, data labeling, prompt evaluation, content safety labeling, and model evaluation. HR Generalists help grow, support, and retain these workforces: recruiting and onboarding raters, establishing annotation guidelines compliance policies with Operations, coordinating scheduling and shift planning for multi-time-zone teams, and partnering with leadership to uphold Illinois and federal employment laws while improving employee engagement and performance.
