Help incubate, launch, and scale new AI-native products at Pelago
Join Pelago’s AI Squad as an early Fullstack Engineer and help define the next generation of behavioral health products. In this role, you’ll ship end-to-end features across React Native, React/TypeScript, and Python services 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 (we use Expo). You should be comfortable writing Swift and Kotlin and exposing that functionality to RN.
This is a hybrid role with a high-collaboration rhythm (4 days/week in our NYC office).
In this role you will…- Build, ship, and maintain cross-platform applications in React Native and React/TypeScript (web) from prototype to production.
- Turn AI research into product: instrument experiments, validate hypotheses, and iterate quickly on research previews on the path to live product.
- Partner cross-functionally (Design, Product, Backend, Clinical) to deliver accessible, reliable interfaces that handle real-time data.
- Integrate & evolve APIs (REST), help shape contracts, and ensure graceful states (loading, error, empty) and resilient data flows.
- Use AI to raise velocity & quality (Claude Code, Codex) alongside strong tests, performance checks, and WCAG-minded reviews. (Pelago also has a dedicated AI budget for preferred tooling!)
- Strengthen foundations: evolve the design system and improve CI, code review, and releases to increase confidence and speed.
- 3+ years in React Native, 7+ years building production software
- Ability to lead React Native work from prototype to GA, setting approach, coordinating APIs, and driving releases and post-launch improvements independently.
- Strong grasp of component architecture, design patterns, and state management (e.g., Tanstack Query, Zustand).
- Comfortable integrating backends (REST/GraphQL), working with real-time/streaming data, and shaping API contracts.
- Write clean, scalable, maintainable code with unit/integration tests and clear documentation.
- Sharp UX sensibility and attention to detail; commitment to accessibility (WCAG).
- Fluency with AI coding assistants (e.g., Claude Code, Codex) and the judgment to verify outputs.
