Responsibilities
- Multi-tenant data architecture schema design, data isolation, and performance at scale.
- Payment and transaction infrastructure webhook processing, idempotency, reconciliation, and payout flows across multiple gateways.
- APIs consumed by web and mobile clients have a clean contract design, versioning, and error handling.
- Async job pipelines, Redis for caching, notifications, and crons for scheduled workflows.

- End-to-end ownership instinct, you've shipped features from spec to production, not just implemented tickets.
- Comfort with async patterns, queues, retries, idempotency, and race conditions.
- Payment domain exposure: UPI, gateway webhooks, reconciliation, settlement flows.
- In a multi-tenant SaaS context, you've thought about data isolation, tenant-level configs, and shared infra.
- You've debugged a production incident under pressure and can tell the story clearly.
