Senior Software Engineer, Marketplace Experience

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 Senior Software Engineer to play a key role in improving the reliability, scalability, and personalization of Grow’s marketplace experience. This engineer will help shape the technical vision of the Marketplace Experience team while taking end-to-end ownership of how clients are matched with providers across our platform. In this role, you’ll work across backend services, data pipelines, and experimentation infrastructure to ensure our marketplace is observable, resilient, and continuously improving. You’ll join a high-impact team responsible for some of Grow’s most business-critical systems. This role sits at the intersection of product, data, and engineering and is ideal for someone who enjoys operating in ambiguous problem spaces, driving clarity in complex systems, and contributing to long-term technical direction while still shipping meaningful improvements. Why the Role Matters: Grow’s marketplace is the backbone of how clients access care. As the business scales, the marketplace must evolve from a collection of incrementally improved systems into a well-designed, reliable, and extensible platform that supports personalization, experimentation, and rapid iteration. This role is critical to that evolution. By owning marketplace systems end to end and helping shape technical direction, this engineer ensures that improvements to matching, personalization, and discovery are built on a foundation that is scalable, observable, and resilient. Their work directly impacts client outcomes, provider success, and Grow’s ability to grow efficiently so we can continue on our goal of expanding access to high-quality mental healthcare for millions of Americans.
