People Operations Manager

Overjet • San Mateo, CA

2d • Hybrid

About The Position

The People team is small, high-leverage, and building the operating infrastructure that a company at our stage needs. This role is at the center of that. This is not a support role. You are the operational backbone of People at Overjet — the person who ensures payroll closes without error, new hires feel set up for success on Day 1, the San Mateo office feels alive, and every HR process runs like it was built by someone who is a systems thinker. You'll own systems end-to-end. You'll use AI tools as a genuine force multiplier. You'll report directly to the Director of People & Performance with real visibility into how the business runs. The right person sees a broken process and fixes it before being asked. They're as comfortable running multi-state payroll as they are ordering snacks and setting up the AV for a company all-hands. They help us build a people focused organization.

Requirements

• 4–5 years of People Operations or HR Generalist experience, with at least one stint at a startup or high-growth company
• Proven Rippling ownership — you've built workflows, configured modules, run payroll, and kept data clean; you're not just a user
• Multi-state payroll experience; international EoR (Deel or equivalent) familiarity strongly preferred
• Active AI tool user — you've used Claude, to meaningfully get work done, not just to experiment
• Benefits administration experience: you've run or supported open enrollment and can manage a broker relationship
• Track record of managing competing priorities without things falling through the cracks
• Demonstrated discretion with sensitive information, comp data, PIPs, offboardings, employee relations
• Clear, direct communicator - written and verbal

Nice To Haves

• Extreme ownership. You don't wait to be asked. If something is broken, you fix it. If something is missing, you build it.
• Systems thinker. You see the upstream and downstream of every process before you build it.
• Detail obsessed. Errors and oversight don't happen on your watch.
• Proactively communicative. You're surfacing the issue before your manager sees it.
• AI-forward. You reach for AI tools the way other people reach for spreadsheets — first instinct, not last resort.
• Creative. You make the office feel like a place people want to be and people programs feel human, not bureaucratic.
• Calm under pressure.
