Senior Platform Engineer

Job Description

Charlie Health exists to change that. Our mission is to connect the world to life‑saving behavioral health treatment. We deliver personalized, virtual care rooted in connection—between clients and clinicians, care teams, loved ones, and the communities that support them. By focusing on people with complex needs, we're expanding access to meaningful care and driving better outcomes from the comfort of home.
