Your Key Responsibilities
  • Design, implement, test, and ship native Android features in Kotlin for Ready1.
  • Build and evolve Jetpack Compose interfaces while thoughtfully migrating legacy RecyclerView and XML components.
  • Implement and maintain secure authentication and session flows using technologies such as MSAL, Azure AD B2C, biometrics, and passkeys.
  • Integrate REST APIs (Retrofit / OkHttp) with resilient loading, error, retry, and empty states, including support for multi-region routing.
  • Contribute to real-time chat and video experiences using SignalR, WebSockets, and Azure Communication Services.
  • Apply and improve app architecture using Hilt dependency injection, ViewModels, repositories, use cases, and clear feature packages.
  • Write unit and UI tests and maintain small, reviewable pull requests that meet quality and coverage standards.
  • Support release activities, including Gradle flavors, signing, Play Console uploads, and post-release crash and log triage.
  • Apply secure mobile practices for tokens, secrets, permissions, local data, logging, and privacy.
  • Collaborate across engineering, product, design, QA, and security to clarify requirements, communicate tradeoffs, and deliver supportable releases.

What You Bring to the Table
  • Typically 3+ years of experience shipping production Android applications.
  • Strong Kotlin and Android SDK fundamentals.
  • Hands-on experience building production interfaces with Jetpack Compose.
  • Experience with coroutines, Flow, and lifecycle-aware Android architecture.
  • Working knowledge of Jetpack components, including ViewModel and Navigation, and Gradle-based projects in Android Studio.
  • Experience integrating REST and JSON APIs (ideally Retrofit / OkHttp) and troubleshooting authentication, token refresh, and unreliable network conditions.
  • An automated testing mindset, with experience in unit testing and Android UI testing.
  • Familiarity with Git, pull requests, code review, and continuous integration.
  • Practical understanding of mobile security, including secure handling of tokens, secrets, permissions, and local data.
  • Clear written and verbal communication and the ability to take a feature from ambiguity to a supportable release.

Bonus Points
  • Experience with MSAL, Azure AD B2C, OAuth/OIDC, passkeys, WebAuthn, or enterprise identity-provider integrations.
  • Experience using Hilt or Dagger dependency injection in a non-trivial application.
  • Experience with real-time clients such as SignalR or WebSockets, or with VoIP and video technologies such as Azure Communication Services or WebRTC.
  • Experience with multi-flavor or multi-environment builds, Play App Signing, internal testing, and staged rollouts.
  • Experience with Crashlytics or similar diagnostics, structured logging, and production incident triage.
  • Experience with cybersecurity products, security operations or incident-response tools, or regulated enterprise software.
  • Experience with accessibility, internationalization, feature flags, or design systems.
