Scope of Work Design multi-step tasks drawn from real HR work — payroll operations, workforce planning, policy application, employee lifecycle processes — with realistic reference files and clear instructions. Define objective grading criteria so two qualified reviewers would reach the same verdict on the same output. Build tasks that require judgment rather than lookup: ones where the right answer depends on reading the materials correctly. Create or source the supporting materials each task needs: policy documents, payroll reports, headcount data, employment agreements. Flag tasks that turn out to be ambiguous or ungradable instead of submitting them anyway. Deliver approved tasks on schedule and at the required quality level. Preferred Qualifications 5+ years of hands-on responsibility in payroll, workforce planning, HR policy, or employee lifecycle operations — direct ownership of the work, not supervisory-only or adjacent exposure. Experience creating or applying structured standards: HR policies, payroll checklists, process documentation, compliance frameworks, or training assessments. Comfortable working across spreadsheets, reports, and policy documents at the same time. HR certification (SHRM, CIPD, PHR or equivalent) is a plus, but not required. Strong English, written and spoken — B2 minimum, C1 preferred. AI or LLM evaluation experience is a plus, but not required.
