 * Publishing application on Apple App Store and Google Play Store. 

* Designing and implementing application updates.

Prerequisites: 

* Experience in development of Android/iOS applications and have deployed them on Google Play/AppStore. 

* In depth understanding of Object-oriented programming languages like Java and C++. * Experience in the Flutter framework. 

* Experience in Dart programming, developing and integration of Rest APIs, GetX state management, Firebase Cloud Messaging API, working with Map APIs, Caching Data using Hive and integration of payment gateways. 

* Comfortable using test cases for debugging code, enhancing performance and reliability.

* Experience in developing Rest APIs using NodeJS and MongoDB. 

* Familiarity using version control tools like Git and IDEs like Android Studio, VS Code etc.

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.

Roles and Responsibilities:

• SDK Development: Contribute to the development of our native Android SDK, ensuring high availability and seamless payment experiences for a diverse merchant base across a highly fragmented device and OS ecosystem.
• 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.

CometChat Overview

CometChat is a full-stack conversational platform built to unify every layer of interaction - bringing together real-time conversations (chat, messaging, voice, and video), AI Agents, moderation, notifications, and analytics in one modular, developer-first solution.

We were also recognized on Forbes' 2026 America's Top 500 Startup Employers List - a reflection of the team and culture we've been deliberate about building.

We believe the interface of the future is conversation - not clicks. Every app will soon have an AI layer that's as native as text messaging today. That's why we're building the infrastructure for the world's AI-powered conversations - from human-to-human, to human-to-agent, to multi-party collaboration with AI in the mix.

From AI onboarding assistants that get users productive in minutes, to copilots that perform complex workflows in-app, to intelligent moderators that protect and guide communities in real time - our AI Agent platform makes it all possible.

With CometChat's ready-to-use UI kits, powerful SDKs, and our Full Stack AI Agent Platform, product teams across startups and enterprises can launch safe, scalable, and smart in-app interactions faster than ever.

Why Join Us Now

We're at the tipping point where AI becomes a native part of every conversation. At CometChat, you'll help shape a future where users can talk to their apps as naturally as to a friend - where agents think, reason, act, and collaborate with humans in real time.

You won't just be joining a product team - you'll be building the standard for AI interaction layers: agent-aware UI, intelligent guardrails, rich actions libraries, and multi-party collaboration between people and AI.

If you want to help define how the next billion users will communicate - and push the boundaries of what's possible in real-time, AI-powered engagement - we'd love to work with you.

What we mean by AI-native

AI-native here means you build with agents by default. We expect 100% of the code to be generated via agentic tools (Cursor, Claude Code, and similar), while you own everything that actually matters: problem framing, architecture, tradeoffs, review quality, tests, performance, and security. This is not "vibe coding." The code is generated. The thinking is yours. You should be great at steering agents, validating output, catching subtle issues early, and debugging code you did not manually write.

Why AI-native

Software development is changing permanently, and we are leaning all the way in. You will work in a team that ships fast with agents, where your leverage comes from judgment and systems thinking rather than typing speed. You will get access to whatever AI tools you need (Cursor, Claude Code, or anything else that makes you effective), and the freedom to use them aggressively. If you want to operate at the edge of how modern engineering gets done and level up your output, this role is built for that.

Join us to build where AI meets human connection.
