Lead Security Engineer

Overview

Millions of people across the country are navigating mental health conditions, substance use disorders, and eating disorders, but too often, they’re met with barriers to care. From limited local options and long wait times to treatment that lacks personalization, behavioral healthcare can leave people feeling unseen and unsupported.

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.

As a rapidly growing organization, we re reaching more communities every day and building a team that’s redefining what behavioral health treatment can look like. If you re ready to use your skills to drive lasting change and help more people access the care they deserve, we’d love to meet you.

Charlie Health is seeking an experienced Lead Security Engineer to join our Information Security team. In this role, you will partner closely with engineering and product teams to embed secure development practices across the entire software development lifecycle (SDLC). You will be the subject matter expert on application security, guiding the business in building secure, scalable and HIPAA-compliant software solutions.

We’re a team of passionate, forward-thinking professionals eager to take on the challenge of the mental health crisis and play a formative role in providing life-saving solutions.
