At Hark, we are building the most advanced personal intelligence in the world.
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
More about this 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.
We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines. While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world.
To get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems.
You'll own the frontend experience of Hark: the interfaces people see, touch, and talk to every day.
That means building UI that keeps up with a real-time, streaming AI agent. Interactions that feel instant. State that stays coherent across voice, text, and vision. The kind of polish that makes people trust what they're using.
This is a high-ownership role on a small team. You'll work directly with designers and the engineers building the agent platform, and what you ship will...
