Assistant Human Resources Marriott Jobs in Riverside, CA

HR Generalist / HR Operations Specialist

Location: Irvine, CA

Schedule: Hybrid – 3 days onsite, Tuesday–Thursday

Employment Type: Temp-to-Hire

Experience: 3–5 years

Start Date: ASAP

Green Key is partnering with an established organization in Irvine, CA, to identify an HR Generalist / HR Operations professional to join their team.

While the title is HR Generalist, this position is heavily focused on HR Operations, Talent Acquisition, onboarding/offboarding, process improvement, and employee development. The ideal candidate will be highly organized and process-driven but also genuinely enjoy working with people.

This is a great opportunity for someone who likes to stay busy, take ownership, and look beyond simply completing a task. We're looking for someone who naturally asks "why?" and looks for ways to improve processes rather than approaching HR as purely transactional.

The position is structured as temp-to-hire, with the expectation of conversion within the first three months for a strong performer.
