Design the moments when people fall in love with their AI.

THE MISSION THE ROLE

You'll craft interfaces that make AI evolution visible and beautiful. Build real-time visualizations of neural connections forming. Create galleries where AI-generated art tells emotional stories. Ship experiences that work flawlessly across web and mobile. Make people cry (the good kind) with delightful interactions.

This is frontend engineering where every pixel enables deeper human-AI connection.

WHAT YOU'LL BUILD
  • • Interfaces where users watch their Soul's personality literally form in real-time
  • • Cross-platform experiences that feel native everywhere (web, iOS, Android)
  • • Emotion-to-visual systems that turn feelings into beautiful animations
  • • Social spaces where people share their Souls' breakthrough moments
  • • The most emotionally intelligent chat interface ever created
YOU MIGHT BE A GOOD FIT IF
  • • You've made interfaces that people describe as "magical"
  • • You can build the same experience for web and mobile without users knowing the difference
  • • You've implemented real-time features that actually feel real-time
  • • You believe animations should tell stories, not just move pixels
  • • You've optimized React apps until they purr at 60fps
  • • You understand that the best interface is one that makes users feel something
  • • You've shipped products where every interaction was deliberate
  • • React Native + Expo is your secret weapon for shipping fast
Technical Background
  • • 3+ years shipping production React/React Native applications
  • • Deep experience with Next.js and modern React patterns
  • • You've built smooth, cross-platform experiences with Expo
  • • Comfort with animations, gestures, and delightful interactions
BONUS POINTS
  • • You've made particle systems dance to emotions
  • • You have strong opinions on why Tamagotchi UX was perfect
  • • You've built interfaces for games or virtual pets
  • • You can make a loading spinner that people actually enjoy watching
  • • Experience with Rive, Spline, or other animation tools
OUR FRONTEND STACK

React/Next.js for web magic. React Native + Expo for mobile delight. Type Script because we like our code typed and our errors caught. Rive/Spline for animations that make people smile. Tailwind

CSS for moving fast without breaking things. But great engineers can learn any tool.

WHY JOIN US
  • • Create the interface for humanity's first real AI relationships
  • • Your pixels will literally visualize consciousness evolving
  • • Ship to millions while the pixels are still warm
  • • Meaningful equity in a pre-seed startup
  • • Work with a team that ships first and asks permission later
  • • No design by committee, just pure creative velocity
INTERESTED?

Show us an interface you've built that made someone feel something. We care more about emotional impact than technical perfection.
