The posting

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 hardware partners

Requirements

  • 8+ years of professional UI software development experience
  • Direct experience building user interfaces that run on a device, not only cloud-backed mobile apps
  • Experience working inside or closely with a design team
  • Experience with rapid prototyping, able to build a realistic interactive prototype in days
  • Deep runtime knowledge of at least one major UI framework (e.g. UIKit, SwiftUI, Core Animation, Jetpack Compose, Flutter, or a web-based rendering engine)
  • Proficient in at least one of: C, C++, Rust, Swift, or Dart, and the ability to trace code across language and process boundaries
  • Ability to work with incomplete information in uncharted territory, driving quality and results

Bonus Qualifications

  • Direct experience with or exposure to embedded system or operating system work (e.g. system daemons, IPC, HAL, drivers, firmware)
  • Experience shipping system-level UI apps on embedded devices
  • Experience shipping a system-level UI framework or graphics stack on iOS, Android, Linux and/or VxWorks
  • Contributions to open source UI libraries widely adopted by the community
  • Experience with design tools (e.g. Figma, Origami, Rive, or Principle) and turning their output into production animations
  • Experience building UI design tools (e.g. component libraries, visual or node-graph editors, or interactive prototyping environments)
  • Experience building interfaces driven by voice, vision, sensor, or ML models, including generated interfaces

Compensation

The US base salary range for this full-time position is between $150,000 - $350,000 annually.

The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
