• Build voice and real-time experiences, including streaming audio, live transcripts, low-latency UI, and smooth handling of network and device changes.
• Build reusable UI components and frontend modules, and keep them consistent with our design system.
• Integrate apps and SDKs with backend APIs, WebSockets, and third-party services.
• Own app and SDK releases, including App Store and Play Store publishing, versioning, build pipelines, and CI/CD.
• Monitor crashes, performance, and app health, and fix issues quickly.
• Optimize performance, startup time, memory use, battery use, and accessibility across devices and OS versions.
• Work with backend and AI engineers to turn model and agent capabilities into smooth user experiences.
• Write clean, tested, maintainable code, and lead code reviews that set the engineering standard.
• Mentor junior developers and interns, and share knowledge across the team.
• Estimate work, flag risks early, and communicate trade-offs clearly to product and founding teams.

Experience

• 3-6 years of experience in software development, with a strong focus on frontend or mobile development.
• Strong, hands-on experience building and shipping production apps in Flutter or React Native (either one), with at least one app live on the App Store or Play Store.
• Experience owning features from design handoff to production release.

Technical Skills

• Strong fundamentals in Dart (for Flutter) or JavaScript and TypeScript (for React Native), and a good grasp of mobile architecture patterns.
• Solid understanding of state management, navigation, component architecture, and app lifecycle.
• Experience with REST APIs, WebSockets, and client-server integration, including authentication, error handling, and offline behavior.
• Experience with native integrations, such as platform channels or native modules in Android (Kotlin or Java) and iOS (Swift or Objective-C).
• Experience with publishing and releasing apps, including signing, store reviews, and release management.
• Experience with CI/CD pipelines for mobile builds, for example GitHub Actions, Fastlane, Codemagic, or Bitrise.
• Experience with crash and performance monitoring tools, for example Firebase Crashlytics, Sentry, or similar.
• Strong skills in debugging, profiling, and performance optimization, and comfortable with Git and code review workflows.
• Ability to write clean, tested code, including unit, widget, or integration tests.
• A degree in Computer Science, IT, or a related field, or equivalent practical experience.

Professional Skills

• Strong ownership and the ability to work independently in a fast-paced startup environment.
• Clear communication, and the ability to work with product, design, backend, and AI teams.
• Willingness to mentor others and give and receive feedback openly.

Good to Have

• Experience building or maintaining an SDK, including versioning, backward compatibility, and developer documentation.
• Experience with real-time audio and voice, including WebRTC, audio streaming, speech-to-text, or text-to-speech.
• Knowledge of both Flutter and React Native, or experience with React and web frontends.
• Experience with native Android or iOS development.
• Experience building conversational, AI-driven, or generative UI interfaces.
• Experience in fintech, BFSI, or SaaS products.
• Basic backend awareness (Python, Node.js, or similar) to build features end to end.
• Understanding of UI/UX fundamentals and design systems.

Success in This Role

• Ship reliable mobile and SDK features to production on a regular schedule.
• Keep crash rates and performance within the targets we set together.
• Take full ownership of a product module, from build to release to support.
• Raise the quality of code and reviews across the frontend and mobile team.
• Help junior developers and interns grow.

What We're Looking For

You're a great fit if you:

• Take strong ownership and see a feature through from idea to production.
• Care about app quality, speed, and a smooth user experience.
• Are curious about AI and how it changes the way people use apps.
• Enjoy building SDKs and tools that other developers rely on.
• Can work effectively in a fast-paced startup environment.

Why Join RevRag AI

• Real ownership: your apps and SDKs go into production and are used by real BFSI customers.
• Hands-on work on in-app AI agents and Voice AI, at the frontier of how apps are built.
• Exposure to real-world BFSI workflows across lending, banking, insurance, and fintech.
• Work closely with product, design, backend, and AI engineers to ship.
• Opportunity to shape engineering standards for mobile and frontend as the team grows.
• Work directly with the founders, with a front-row seat to how an AI startup builds a product category from scratch.
