Senior Backend Engineer

Jaipur / Remote· Full-time

We're looking for a senior backend engineer to own the shipping engine — the routing, rating, and reconciliation code that decides how every parcel moves.

What you'll work on

  • The smart-routing engine that picks a courier per shipment (Delhivery / Ekart / India Post) based on serviceability, price, and expected SLA
  • Rate cards, wallet, and the ledger — Decimal-safe, append-only money math
  • Idempotent booking APIs that stay correct even when couriers' APIs don't

What we look for

  • 5+ years shipping production Node.js / TypeScript
  • Comfort with Postgres and Prisma (or willingness to learn fast)
  • Zero fear of a debugger

Apply with a note about the last thing you shipped that surprised you.
