Employment: Full-time The Role

You will own our production stack end to end.

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.

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 secure 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

Robust MySQL/SQL knowledge — indexes, transactions, migrations and EXPLAIN
Production experience with Flutter
Experience with state management such as BLoC
Experience shipping and maintaining a real consumer app
Payment gateway experience, especially webhooks and idempotency
Solid production debugging and problem-solving skills
Ability to work independently and take ownership

Who we're looking for

Someone who takes ownership when things break.

You should be comfortable checking the data before making changes, taking backups before migrations and saying "I don't know, but here's how I'll find out" rather than guessing.If you've built and maintained production systems where payments, subscriptions and customer entitlements actually matter, we'd like to hear from you.
