Own the complete backend for a consumer product handling real-time inventory locking and payment processing — sole backend owner, full architectural responsibility.

Key Responsibilities

● Design and build REST APIs in Node.js + Express + TypeScript

● Design MongoDB schemas with correct atomicity for concurrency-sensitive writes (no double-bookings/double-charges)

● Implement time-based locking using Redis (TTL locks / job queues)

● Integrate a payment gateway server-side — payment intents, signature verification, webhook handling

● Integrate Facebook OAuth login and secure session/token management

● Own deployment to AWS and/or DigitalOcean (Docker, basic CI/CD, S3/CDN as needed)

● Write secure, defensive, production-grade API code and independently debug production incidents

Must-Haves

● Node.js, Express, TypeScript — real type-secure API design





● MongoDB (schema design, transactions, indexing)

● Redis (locks, caching, or queue-based patterns)

● Experience integrating at least one payment gateway server-side, incl. webhook verification

● OAuth-based login integration experience

● Comfortable with AI-assisted coding, but able to defend the security and correctness of every line shipped — this will be tested in interview

Nice-to-Haves

● BullMQ or similar Redis-backed queueing

● Idempotent API design experience

● Docker/docker-compose, broader AWS services (S3, CloudFront, SES/SNS)
