The Opportunity Hinge Health is the leader in Digital Physical Therapy and we are expanding to new areas outside of physical therapy. In May we launched the new Migraine product line https://www.hingehealth.com/resources/press-releases/hinge-health-launches-comprehensive-migraine-care-program/, and now we are building a new team from scratch for a Gastrointestinal (GI) product line. GI is a $135B market in the US alone and after the acquisition of Cylinder Health https://ir.hingehealth.com/news/news-details/2026/Hinge-Health-to-acquire-Cylinder-Health-expanding-into-gastrointestinal-care/default.aspx, we are in a great position to rapidly build new products in the GI space. This is your opportunity to build a brand new product from scratch, defining the product that millions of Americans will see in their healthcare plan next year. As a Senior Software Engineer for GI, you’ll build an understanding for the 60M+ Americans afflicted by this health condition, ensuring that Hinge Health builds a comprehensive end-to-end experience to treat them, run rapid experiments to validate your assumptions, and launch a brand new digital care product for GI. What differentiates HingeHealth from other platforms is our fast pace of innovation blending licensed care providers with AI solutions and medical grade hardware to deliver a complete experience that improves the health of our users. You’ll partner closely with staff engineers, team leaders including cross-functional partners in Product, Design, and Marketing across our hubs in San Francisco, Montreal, and Bangalore to build a new GI product. As a hands-on engineer, you’ll contribute to and review code daily, raise the quality bar, and independently ship impactful improvements to one of our most visible product surfaces.
