THE OPPORTUNITY Join the team that bridges the physical and digital worlds to help millions of people move without pain. As a Senior Software Engineer, you will build the critical software that powers our cutting-edge hardware—specifically our Enso pain relief device. You won’t just be writing code; you will be the glue between our hardware, firmware, and mobile experiences. We are looking for a versatile engineer who thrives in a full-stack environment (React Native, Node.js, TypeScript) and isn't afraid to dive into Bluetooth protocols, complex state management, or backend services to deliver a seamless pain relief experience for our members. WHAT YOU'LL ACHIEVE - In your first 3 months: You will immerse yourself in our device ecosystem, shipping your first features for the Enso experience. You’ll build relationships with Product, Design, and Hardware partners and gain a solid understanding of our mobile-to-device architecture. - In your first 6 months: You will lead the end-to-end delivery of a key initiative (e.g., supporting new hardware device capabilities or new treatment programs). You will actively improve our developer tooling and contribute to architectural decisions tha
