Principal Growth Engineer

About Blueprint

At Blueprint, we’re on a mission to empower therapists with world-class tools so they can focus on what matters most—delivering exceptional mental health care.

Our AI assistant is purpose-built for therapists, automating the administrative tasks that slow them down and enabling them to operate at the top of their license. With Blueprint, therapists aren’t just managing their work; they’re supported by tools that understand the context of each client interaction. Compared to legacy software tools, Blueprint feels more like having the world’s best executive assistant at your side.

Today, over 40,000 therapists use Blueprint to enhance care for hundreds of thousands of clients. We’ve found strong product-market fit and are scaling rapidly to meet demand.

Our organization is very flat, and our team is intentionally small and talent-dense. We like people who are truthseekers, creative, and passionate about improving mental health care.

We’re a remote-first company (U.S. and Canada only, for now) and come together in person a few times a year to connect, have fun, and help shape the future of mental health care.
