## About the role

Hark is an artificial intelligence company building advanced, personalized intelligence. One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory.

## What they're looking for

- Deep frontend expertise. You know modern React (or equivalent), state management patterns, and how to build interfaces that feel great at 60fps
- Experience with real-time UI. Streaming data, websockets, optimistic updates: you've built interfaces where latency and state consistency really matter
- A sharp eye for polish. You notice when animations are off, when loading states feel wrong, when something just doesn't feel right, and you fix it
- Experience shipping consumer products that real people depend on. You understand the gap between a prototype and something someone trusts every day
- Genuine curiosity about AI and agents. You've used LLM-powered products, noticed where the UX breaks down, and thought about what would make it better
- Comfort with ambiguity and fast iteration. You can take a rough idea, prototype it quickly, get feedback, and converge on something that works
