Fireworks AI · Data AI · San Mateo, CA · HR

This role is for a People Operations Lead responsible for the operational backbone of the People team, including HRIS, payroll, benefits, and compliance. The individual will ensure HR data, payroll outputs, and operational processes are accurate, scalable, and synchronized.

What you'd actually do

  1. Own and optimize HRIS infrastructure, people data quality, and system workflows — establishing standards for data integrity, reporting, and audits across all HR systems, including reconciliation between internal systems and PEO/EOR platforms
  2. Lead employee lifecycle operations end-to-end within the PEO/EOR system, ensuring high accuracy, timely execution, and a consistent employee experience
  3. Own payroll operations in partnership with our PEO/EOR — managing inputs, auditing outputs, coordinating off-cycle runs, and serving as the primary point of contact for payroll-related issues and escalations
  4. Own multi-state payroll tax compliance — track active state registrations, monitor new-state expansion triggers, and ensure the PEO/EOR is filing accurately and on time; proactively flag and resolve discrepancies before they become liabilities
  5. Own health and benefits and 401(k) administration within the PEO/EOR and other vendor platform — including open enrollment, life event changes, invoice reconciliation, carrier escalations, and employee inquiries
