Engineering
React Native Mobile Developer, AI Chat UI
Build the AI chat and voice assistant inside our Expo app, with the kind of motion and polish that makes it feel alive, not just functional.
About the role
We're adding an AI assistant to our tenant and manager apps: a chat surface people type or speak into, that drafts messages, answers questions and triggers real actions. The functionality is the easy part. The hard part is making it feel fast, fluid and trustworthy the moment someone opens it.
You will own that surface end to end: the conversation UI, the input states, the loading and thinking states, and the transitions between screens. We want someone who has already shipped work at this level of polish, not someone discovering Reanimated for the first time on our app.
What you'll do
- Design and build the AI chat interface in our Expo (React Native) app: message bubbles, streaming responses, voice input, and smooth transitions between states.
- Own animation and micro-interaction quality: gesture-driven transitions, loading and thinking indicators, and the small details that separate a good app from a great one.
- Work closely with design and backend to turn a rough flow into a shipped, production-quality screen.
- Profile and fix performance issues on real devices, not just the simulator.
- Push back on designs that look great in Figma but won't perform well on a mid-range Android phone, and propose better ones.
What you bring
- 3+ years building production React Native apps, with real experience in Expo specifically.
- A portfolio that includes at least one shipped AI chat, voice assistant, or similarly conversational interface, not just CRUD screens.
- Strong hands-on experience with React Native Reanimated, gesture handling, and building custom, animated components from scratch.
- A genuine eye for visual and motion detail: spacing, timing, easing, and how a screen feels under your thumb, not just whether it compiles.
- Clear communication: you can explain a design or technical tradeoff in writing, not only in code.
Nice to have
- Experience with streaming text or token-by-token rendering in a chat UI.
- Worked with speech-to-text or text-to-speech SDKs on mobile.
- Familiarity with NativeWind, Moti, or similar animation and styling layers on top of React Native.
- Shipped an app to both the App Store and Play Store, including the native build and release process.

These aren't our designs. They're the quality bar for motion and polish we're hiring for.
