People Operations Manager
Lead the Future of Dentistry.
Overjet is the world-leader in dental AI. Already, thousands of dental providers and insurers rely on our platform to deliver the best possible care. Now, we’re looking for talented people to fulfill our mission: improve oral health for all.
Overjet is where builders become leaders. Everyone here loves to make new things: new products, new partnerships, new content, and a new category of AI technology. And as Overjet grows ridiculously fast, so will you.
Simply put, there’s no better place to accelerate your career. Come join us!
The Role
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.
