  • Partner with product managers, designers, and researchers to translate user experience requirements into elegant, maintainable solutions.
  • Establish coding standards, testing strategies, and development patterns that raise the quality bar for frontend engineering.
  • Mentor engineers and act as a multiplier for frontend development expertise across the broader team.
  • Investigate new frontend technologies, frameworks, and performance techniques, and guide their adoption when appropriate.
  • Represent frontend/OS needs in technical and architectural discussions.

Requirements

  • 5+ years of software development experience, with significant experience building React Native apps or high-performance JavaScript/TypeScript applications.
  • BS/MS degree in Computer Science or equivalent.
  • Expertise in native Android development (Kotlin/Java/Gradle) and shipping applications to the Google Play Store.
  • Strong expertise in frontend performance profiling, optimization, and debugging.
  • Passion for delivering world-class user interfaces with exceptional performance.
  • Deep understanding of cross-platform architecture and how to bridge between JS and native modules.
  • Proven track record of delivering production-quality mobile or desktop applications with React Native.
  • Experience designing scalable frontend architectures and reusable UI frameworks.
  • Strong collaboration skills and ability to work closely with native engineers, designers, and product managers.
  • Demonstrated technical leadership: leading projects, mentoring engineers, or setting engineering strategy.

Bonus

  • A track record of building social, community, gaming, or other consumer products.
  • Familiarity with VoIP, call dialing and ringing flows in Android/React Native
  • Experience with accessibility, internationalization, and UI testing frameworks.
  • Familiarity with CI/CD pipelines and modern build systems for frontend development.
  • Previous experience at an early-stage startup or on a zero-to-one product team.
