Location: Mumbai
Experience: 3+ years
Employment: Full-time

The Role
You will own our production stack end to end.
Backend: PHP + MySQL powering our API, admin panel and content delivery
App: Flutter with BLoC architecture, optimized for Android devices including low-end phones
Payments: Razorpay (UPI AutoPay) and Google Play through RevenueCat — subscriptions, webhooks, renewals, trials, cancellations and reconciliation
Infrastructure: AWS EC2, S3, CloudFront, deployments, logs and backups
This is a production-ownership role, not a feature-factory role.
When a paying customer says, "The app says my account is not active," you should be able to open the database, check webhook logs and gateway records, find the actual problem, fix the customer issue and then fix the underlying bug.
What you'll actually do
Maintain the subscription lifecycle across Razorpay and Google Play
Build reliable, idempotent webhook handling
Handle renewals, trials, cancellations, refunds and entitlement syncing
Develop and maintain Flutter features
Design MySQL schemas and safe database migrations




Debug production issues across app → API → database → payment gateway
Manage deployments, logs, cron jobs and backups
Work on video delivery using HLS, S3, CloudFront and signed URLs
Improve app performance, stability and reliability
You should have
3+ years PHP experience, comfortable with raw PHP/PDO
