• Identify subtle errors, edge cases, and failure modes in model reasoning on nuanced people decisions.
• Provide clear, structured written rationale to explain why a given answer is correct, incomplete, or wrong.
• Collaborate with the team to refine evaluation rubrics and raise the quality bar for HR domain content.

Ideal Qualifications

• 3+ years of professional experience in Human Resources or People operations (in-house, consulting, or agency).
• Depth in one or more HR sub-domains: talent acquisition/recruiting, compensation & benefits, HR business partnering, employee relations, learning & development, HR compliance, or HR analytics.
• Strong command of core HR frameworks, employment-law fundamentals, and people-decision tradeoffs.
• Excellent written communication — able to explain nuanced reasoning clearly and concisely.
• Sharp attention to detail and comfort evaluating the quality of others' work.
• An HR credential (SHRM-CP, SHRM-SCP, PHR, or SPHR) is preferred but not required.
