Interface Designer Jobs

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 The Embedded Software team is looking for a Frontier UX Engineer to build the software that turns design intent into interfaces people can pick up and use. You will work closely with Design, taking ideas, use cases, and specifications from early prototype through a world class shipped product, pushing the UI experience to its limit. Much of the work has no precedent, requiring comfort with unclear requirements and problems that cross design and several software layers. We care a lot about how the product feels to use, and we want someone who shares that mindset. Responsibilities Turn design specifications, use cases, and rough ideas into shipping interfaces, from early prototype through production on real hardware Own execution: take a prototype the whole way to something that ships, with the quality bar held at each step Find where the design language outruns the platform, and push the UI software at every layer needed to close the distance Advise designers on what the system is actually capable of, early enough for it to change the design Shape the UI runtime and system architecture with requirements drawn from real designs rather than hypotheticals Own the end-to-end development of user experiences alongside design, firmware, and hardw
