About The Position

We are seeking a Frontend Engineer to help us craft intuitive, high-performance user interfaces that our providers love.

You care about clean, modular code, and can collaborate closely with design and product to bring elegant experiences to life.

This role requires a dynamic individual who can drive frontend architecture decisions and work cross-functionally across engineering, design, and product teams.
