About The Position

We’re hiring a Senior Software Engineer II 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.
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.
