About the role

Role within the Embedded Software team to translate design intent into shipping UI interfaces on real hardware, working closely with Design to push the UI experience and align system capabilities with design specifications.

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

Qualifications

  • 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
