Coordinates assigned onboarding projects and initiatives (e.g., orientation redesign, onboarding playbook development, system or workflow rollouts, new-site or acquisition onboarding waves) — building the task plan, tracking milestones and dependencies, coordinating contributors across departments, and reporting status to the Onboarding Operations Manager. The role independently manages caseloads of new hires, providers, students, or fellows from offer acceptance through Day 1 and beyond, exercising judgment to resolve issues, coordinate across departments, and ensure compliance, while escalating matters of significant risk to the Onboarding Operations Manager.
