Human Resources Generalist

LHH
Ontario, CA

We’re looking for a hands-on HR Manager / Senior HR Generalist to step into a highly visible role supporting a fast-paced, blue-collar environment. This is an in-office role for someone who enjoys being in the details, owns benefits and leaves in-house, and is comfortable operating without a plug-and-play HR playbook.


This role is intentionally flexible and will evolve around the strengths of the first senior HR hire.


What You’ll Own:


Core HR / Generalist Support

  • Serve as a hands-on HR partner supporting ~600 employees
  • Operate comfortably “in the weeds” in a high-volume, operational environment
  • Apply strong working knowledge of California HR fundamentals (wage & hour, LOAs, compliance basics)
  • Understand HR team structure, capacity planning, and employee-to-HR ratios

Benefits Administration (Critical)

  • Own end-to-end benefits administration in-house
  • Hands-on experience with:
  • EDI feeds (setup, testing, troubleshooting)
  • Carrier setup, transitions, and renewals
  • Medical billing and invoice reconciliation (auditing, not just payment)
  • Identify discrepancies and partner with carriers to resolve issues
  • Advanced Excel skills required (VLOOKUPs, pivot tables)
  • Experience with electronic benefits platforms (no paper enrollments)

Leaves of Absence (Managed In-House)

  • Working knowledge of California Leaves of Absence
  • Directly manage high LOA volume, including seasonal spikes
  • Own LOA forms, timing, and compliance tracking
  • Escalate complex cases appropriately while handling day-to-day LOAs independently
  • Experience managing long-term leaves (12+ months)

Recruiting Exposure (Not a Recruiter Role)

  • Exposure to full-cycle recruiting preferred, including:
  • Market and compensation analysis
  • Job descriptions
  • Phone screens and interviews
  • Must have “touched” recruiting as part of an HR role
  • Recruiting is a shared responsibility (no dedicated recruiter)

Environment & Culture Fit

  • Construction experience strongly preferred
  • Manufacturing experience considered transferable

Comfortable in:

  • Fast-paced, high-volume environments
  • Mass hiring cycles and occasional layoffs
  • Thick-skinned, pragmatic, and not easily offended
  • Comfortable working with candid, direct managers
  • Relationship-driven and trusted by leadership
  • Flexible, adaptable, and not clock-watching
