People Lead

About the role

We are hiring River AI’s first People Lead to own the human resources function and the related systems that keep the company running: HR, payroll, benefits, insurance, and operations. You'll set them up, run them day to day, and keep improving them as we grow.

The role has unusual reach. You will shape nearly everyone's experience here, from a new hire's first day to the environment every employee works in, and you will be trusted with the judgment calls that come with that.

We are a team that is genuinely interested in working smarter. You will have real room to deploy AI to take the repetitive or tedious parts of operations off your plate, so your time goes to meaningful work.

Who we are

At River AI, our mission is to create personal AI owned and shaped by each individual. To achieve this, we are building the full stack required for people and organizations to create AI models of their own—from training infrastructure and open-weight model post-training to personal hardware and next-generation interfaces.

We are scientists, engineers, and builders from the industry’s leading technology companies and AI labs. Our team has experience scaling consumer products to hundreds of millions of users and building the infrastructure behind frontier AI systems.

What you'll do 

• Own HR operations end-to-end: HRIS administration (Rippling), onboarding and offboarding, benefits administration, and employee records.
• Run payroll operations end-to-end, including benefits–payroll integration; review benefits charges and invoices for accuracy.
• Own company insurance and benefits programs — health, wellness, and business — sourcing providers and comparing quotes as needs change.
• Coordinate closely with Legal and IT on compliance activities.
• Engage and manage the implementation of EORs, contractors, and consultants.
• Build employee training — including policies and norms for an AI-native workplace (acceptable use, data handling).
• Handle sensitive employee matters and information with professionalism and sound judgment.
• Own workspace and commercial real estate: lease administration and negotiations, workspace and equipment setup, utilities, physical security, and vendors for networking, deliveries, and the cafeteria program.
• Support office events and team meetings.
• Identify recurring problems, put better processes (and AI tooling) in place, and drive issues to resolution.
