Senior Software Engineer - Full Stack

About Us: Grow Therapy is on a mission to serve as the trusted partner for therapists growing their practice, and patients accessing high-quality care. Powered by technology, we are a three-sided marketplace that empowers providers, augments insurance payors, and serves patients. Following the mass increase in depression and anxiety, the need for accessibility is more important than ever. To make our vision for mental healthcare a reality, we’re building a team of entrepreneurs and mission-driven go-getters. Since launching in February 2021, we’ve empowered more than ten thousand therapists and hundreds of thousands of clients across the country and insurance landscape. We’ve raised more than $178mm of funding from Sequoia Capital, Transformation Capital, TCV, SignalFire, and others. The Opportunity We're hiring a Full Stack Senior Software Engineer to help build and evolve the systems that power Grow Therapy's platform. In this role, you'll work across the stack to design, implement, and ship features that directly impact how clients and providers connect, communicate, and access care. You'll join a collaborative, product-focused engineering organization where technical work is closely tied to learning, iteration, and real-world outcomes. This role is ideal for an engineer who takes pride in writing clean, maintainable code, thinks deeply about system behavior, and is energized by the opportunity to grow alongside a fast-moving team. Why This Role Matters Access to mental healthcare in America is still deeply fragmented and Grow Therapy is building the platform to fix that. We connect clients, providers, and health plans in a single integrated system, and the software our engineers ship directly shapes whether people can find and afford the care they need. We're growing fast - nearly 22,000 clinicians, over 1.4 million clients, and on track to surpass 10 million sessions in 2026 and we see ourselves as a generational company with a long way still to go. Engineers who join now have a real opportunity to build systems that matter at meaningful scale.
