About the Role
We are a consumer technology product company building products such as Bhaktilok (Devotional) and CashAlert. We are looking for a Full Stack Flutter & Kotlin Developer who can take complete ownership of building mobile products from scratch — from frontend and backend to APIs, payment gateway integration, third-party SDKs, deployment, and production support.
This is a hands-on engineering role for someone who can independently turn a product idea into a production-ready consumer application.
Key Responsibilities
- Build complete consumer applications from scratch using Flutter/Dart and Kotlin.
- Develop high-quality, scalable Android and iOS applications using Flutter, with Kotlin for native Android development and integrations.
- Develop and maintain backend services, REST APIs, databases, and server-side architecture.
- Integrate and manage payment gateways (PG), subscriptions, payment APIs, and transaction flows.
- Integrate, configure, troubleshoot, and maintain third-party SDKs and APIs.
- Develop native Android modules and integrations using Kotlin when required.
- Implement authentication, OTP, push notifications, analytics, crash reporting, deep links, and other essential mobile services.
- Design efficient database structures and API architecture.
- Handle Android/iOS builds, release management, deployment, and production debugging.
- Optimize applications for performance, scalability, reliability, and security.
- Work with cloud services and backend infrastructure.
- Take complete ownership of features from requirement → architecture → development → testing → deployment → maintenance.
- Debug production issues across the frontend, backend, APIs, database, native code, and third-party integrations.
- Work closely with the product team to convert ideas into functional consumer products.
Required Technical Skills
- 2–5 years of professional software development experience.
- Strong expertise in Flutter and Dart.
- Good hands-on experience with Kotlin and Android development.
- Strong understanding of Flutter architecture, state management, navigation, animations, and responsive UI.
- Strong knowledge of Android SDK, Kotlin, Gradle, and native Android integrations.
- Experience with REST APIs, JSON, API authentication, and backend integration.
- Strong backend development experience using technologies such as Node.js, PHP, Python, or similar.
- Strong knowledge of SQL databases such as PostgreSQL/MySQL.
- Experience with payment gateway integration and subscription/payment systems.
- Experience integrating and managing third-party SDKs and APIs.
- Experience with Firebase, including FCM, Analytics, Crashlytics, etc.
- Good understanding of Git/GitHub and modern development workflows.
- Experience with Android/iOS builds, signing, debugging, and publishing.
- Understanding of cloud infrastructure and deployment.
Good to Have
- Experience with Supabase.
- Experience with AWS, Google Cloud, or Cloudflare.
- Experience with payment gateways such as Cashfree, Razorpay, Stripe, or similar.
- Experience building subscription-based consumer applications.
- Experience with Google Play Billing and Apple In-App Purchases.
- Experience with Redis, queues, background jobs, or serverless architecture.
- Knowledge of Swift/iOS native development is a plus.
- Experience launching and maintaining consumer applications at scale.
Who We’re Looking For
We are looking for someone who is not limited to Flutter UI development.
You should be comfortable taking a product idea and figuring out how to build and launch it end-to-end.
You should be able to work across:
Flutter → Kotlin → Backend → API → Database → Payment Gateway → Third-Party SDKs → Cloud → Deployment → Production Support
Strong problem-solving ability, ownership, attention to detail, and the ability to work independently are extremely important.
Candidates with proven experience building and launching complete products from scratch will be strongly preferred.
