About Hark

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.

About the Role

At Hark, you'll build the desktop experience that brings our intelligence to where people do their work every day. We're looking for exceptional engineers with deep C++ experience and a background in Chromium or Electron-like application frameworks, who want to shape how a proactive AI lives on the computer.

You'll architect and build the native foundations of Hark's desktop app on macOS and Windows, from OS-level integration and system APIs to the features that let Hark see, listen, remember, and act alongside users across their apps and the web. You'll own features end-to-end, work closely with researchers, model engineers, design, and hardware teams, and help define what it feels like to have an intelligent agent built into your desktop. This role is a fit for engineers who thrive in fast-paced environments, take initiative on high-impact problems, and care deeply about building software that is fast, stable, and feels native on every platform.

Responsibilities

• Own features from concept and design through implementation and launch, serving as a desktop and native platform expert on the team.
• Build the core of Hark's desktop app, while contributing to features across the full stack.
• Build the native capabilities that make Hark multimodal on the desktop, including voice input, audio, screen understanding, and experiences where agents take actions on a user's behalf across apps and the web.
• Integrate deeply with macOS and Windows so Hark feels at home on each platform, including system APIs, permissions, notifications, background processes, and connections to Hark hardware and other devices.
• Design and implement clear, reusable API in languages like Rust, C++, Typescript, Go, along with the tooling and infrastructure used to build, test, and deploy them.
• Partner with researchers and model engineers to bring new model capabilities to the desktop quickly, building foundations that shorten the path from research to product.
