• Direct ownership of talent programs, employee relations matters, or compensation design.

• Mercor is seeking senior HR professionals to build evaluation tasks for AI systems operating in talent management, employee relations, and organizational design contexts.

• The workflows are calibrated to the organizational scale, compliance stakes, and scope of major workforce programs at large companies.

• Contributors design HR scenarios, draft reference outputs, and write rubrics that capture how senior HR leaders think.
