The Role:

We are looking for a Software Development Engineer (Android) to join our Core Payments team at Razorpay. In this role, you will be responsible for developing and scaling our Android SDK, the critical integration point used by thousands of merchants to process payments across multiple geographies.

You will work closely with product and backend engineering teams to design high-performance features, ensuring the SDK remains secure, lightweight, and developer-friendly. This role offers the opportunity to solve complex engineering challenges involved in building financial infrastructure that operates at massive scale.

• Engineering Excellence: Write clean, maintainable, and modular code. Architect solutions that are resilient across different host app environments, OEM customisations, and Android OS versions.
• Automation: Design and implement robust automation for tests, builds, and performance profiling. If a task is repetitive, you are expected to automate it.
• Instrumentation: Build deep telemetry within the SDK to provide real-time insights into success rates and latency, enabling data-driven product decisions.
• Security: Implement industry-standard security protocols, including SSL pinning, ProGuard/R8 obfuscation, and runtime integrity/root-detection checks, to protect sensitive transaction data.

Mandatory Qualifications:

• 2+ years of experience in native Android development using Kotlin (working knowledge of Java is expected for legacy interoperability).
• Systems Design: Solid understanding of OOPS principles and architectural patterns (e.g., MVVM, MVI, or Clean Architecture).
• Cross-Platform Knowledge: Practical experience with bridge-based frameworks such as Flutter, React Native, or Cordova.
• Technical Depth: Strong proficiency in Kotlin Coroutines/Flow, Jetpack libraries, Activity/Fragment lifecycles, and both XML Views and Jetpack Compose.
• Debugging: Proficiency in using Android Studio Profiler, LeakCanary, and network inspection tools for memory management, CPU profiling, and network debugging.

Good to Have:

• iOS Stack Experience: Familiarity with Swift is highly preferred to help maintain feature parity and align API design across platforms.
• Deployment & Tooling: Knowledge of Gradle build customisation, publishing to Maven Central, and CI/CD tooling (e.g., Fastlane, GitHub Actions) for automated distribution.
• Open Source: Active contributions to GitHub or a portfolio of apps published on the Google Play Store.
