Job description

Antidote Health is a tech-driven health insurance company on a mission to make healthcare easy, accessible, and more affordable. We’re rethinking how healthcare works—using technology to remove the friction, complexity, and delays that define the traditional system. Instead of navigating paperwork, long waits, and disconnected experiences, we’re building a simpler, more connected way for people to get care.

Our platform combines health coverage, virtual care, and a modern member experience into one seamless system designed to help people actually use their benefits.

We offer Affordable Care Act (ACA) health plans in Arizona and Ohio, and we’re growing quickly. We’re building a company focused on solving real problems—with real impact on people’s lives.
