About the role
Every session on Expertbells depends on a chain of backend work: a mentor's calendar, a held slot, a payment, reminders, a video link and finally a payout. When any link breaks, a founder misses a call they were counting on.
You will own a large share of that chain. The services are Node and TypeScript on Postgres, with queues for anything that has to happen later.
What you'll do
- Design and build APIs for scheduling, bookings, refunds and mentor payouts
- Integrate with calendar providers, payment gateways and messaging services
- Write background jobs for reminders, reconciliation and reporting
- Add monitoring and alerts so problems surface before users report them
- Take part in a light on-call rotation shared across engineering
You may be a fit if
- You have built and run backend services in production for 2+ years
- You are comfortable with SQL, schema design and database migrations
- You think about idempotency and retries when money is involved
- You write tests for the parts that would hurt most if they broke
Big plus
- Experience with time zones and recurring availability rules
- Familiarity with Indian payment rails such as UPI and GST invoicing
