Role Description Our client, a fast-growing telehealth startup, is seeking a Founding Mobile Software Engineer. This is a foundational hire responsible for building the company's first native mobile application using React Native. - Help stand up the mobile app from scratch. - Make key architectural decisions. - Establish the technical patterns that future engineers will build upon. The ideal candidate has shipped and maintained React Native apps in production and understands the boundaries between React Native and native iOS/Android development. You should be comfortable working primarily in TypeScript and React, while also able to drop into Swift or Kotlin when needed (e.g., HealthKit integrations, push notifications, video SDKs). The team views mobile and web as one unified product surface — not separate teams — so you should also be comfortable contributing to a Next.js frontend when needed. Qualifications - 3+ years of experience building mobile applications, with meaningful production experience in React Native. - Strong technical fundamentals in React Native and experience with Expo (build tooling, OTA updates, native module configuration). - Comfort working with native iOS and/or Android (Swift, Kotlin). - Experience operating in ambiguous, fast-paced startup environments (prior startup experience preferred). - Familiarity with modern full-stack environments (e.g., Ruby on Rails, Postgres, TypeScript) and architecting shared code between mobile and web codebases is a plus. - Clear communicator who can articulate technical decisions thoughtfully and succinctly. - Entrepreneurial mindset — has built products and can think beyond code (e.g., GTM strategy, early customer acquisition). - Strong mission alignment and excitement about building meaningful healthcare technology (prior healthcare experience not required). Benefits - This is an opportunity to define the mobile foundation of a telehealth platform and have outsized impact from day one.
