Ready1 enables teams to triage incidents, coordinate response activities, join secure video bridges, and communicate in real time across Android and iOS platforms.
In this role, you will own secure, production-ready Android features for Ready1 from design through Google Play release. You'll collaborate with iOS, backend, product, design, QA, and security partners to improve reliability, quality, and delivery speed for identity and incident-response teams operating across regions.
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 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
Semperis protects hybrid Active Directory and Entra ID environments for enterprises worldwide, helping security and identity teams detect, respond to, and recover from identity-driven attacks.
