.NET Integrations Intern - Payments and Webhooks

Integrations are where the interesting bugs live

Employers buy job credits through Razorpay, and each of those payments comes back to us as a webhook that has to be verified, deduplicated and reconciled against an invoice. Over three months you take ownership of that pipeline: signature verification, retry handling, and the reconciliation job that catches the handful of payments slipping through every week.

Beyond payments

You will also build a connector to a third party resume parsing API, wrap it behind an interface so it can be swapped without touching callers, and write the contract tests that tell us the moment their response changes shape. It is all C# on .NET 8, hosted on Azure, with Polly handling retries and circuit breaking.

Honest terms

This position is unpaid. What is offered in exchange is unusually specific work for an internship, complete ownership of a subsystem rather than a corner of one, and a mentor who reviews your code line by line instead of approving it to be pleasant. Remote from anywhere in India, flexible hours, and a written reference at the end that describes exactly what you built.
