Sydney, New South Wales, Australia Sirius People Full time $90,000 - $120,000 per year
The Role:Technical Requirements:
  • 4+ years of professional experience in mobile application development, either using React Native or native technologies (Swift/Objective-C for iOS, Kotlin/Java for Android).
  • Strong proficiency in TypeScript and deep familiarity with the React Native ecosystem, including state management, navigation, native modules, and modern React patterns.
  • Proven ability to build, test (with tools like Jest, Detox, or Appium), and deploy high-quality apps to both the Apple App Store and Google Play Store.
  • Comfortable with mobile development tools and workflows such as Expo, Xcode, Android Studio, Fastlane, and CI/CD pipelines.
  • Solid understanding of performance tuning, accessibility, and platform-specific UI/UX best practices.
What You'll Do:
  • You'll take the lead in building well-structured, efficient mobile apps using React Native and TypeScript-occasionally leaning on native tools like Swift or Kotlin when needed-to solve real user problems with clean, scalable code.
  • You'll work closely with designers, product managers, and other engineers to turn complex requirements into intuitive mobile experiences, aligning technical decisions with business goals.
  • From concept to app store release, you'll manage the full lifecycle of mobile features, ensuring they're high-quality, performant, and tailored to the specific needs of iOS and Android platforms.
  • As a mobile specialist, you'll influence architectural decisions, shape our mobile development standards, and contribute to evolving components or internal frameworks that support rapid, reliable delivery.
  • You'll play a key role in upholding code quality-reviewing pull requests, improving testing strategies across unit, integration, and UI levels, and advocating for automation wherever possible.
  • You'll continuously look for ways to improve-whether it's refactoring parts of the codebase, streamlining developer workflows, or optimizing app performance.
  • Mentorship is part of the role: you'll support teammates looking to grow their mobile skills and help build a strong engineering culture around mobile best practices.
