Overview of the Role: Help incubate, launch, and scale new AI-native products at Pelago: Join Pelago’s AI Squad as an early Frontend Engineer and help define the next generation of behavioral health products. In this role, you’ll ship end-to-end features across React Native and React/TypeScript, transforming prototypes into production-ready experiences. Your work will move fast—from hypothesis to research preview to live product—and will be grounded in clinical safety, accessibility, and measurable outcomes. You’ll bring engineering craft and a sharp UX eye within a team that values thoughtful design, clean architecture, and meaningful user impact, leveraging modern AI-enhanced development tools to move faster and build better. While most of our surfaces are React Native, some use-cases will require platform-specific code. You should be comfortable writing Swift and Kotlin and exposing that functionality to RN.
