As a Customer Success Engineer, your primary responsibility is to ensure the technical success of Cashfree merchants. You will act as a technical consultant, helping high-value clients integrate with the platform's suite of products. This involves deep-dive troubleshooting, optimizing integration performance, and providing technical guidance during the onboarding phase.

You will collaborate extensively with the engineering and product teams, acting as a feedback loop. When you identify recurring integration hurdles or product gaps, you will be expected to escalate these to the product team to drive long-term improvements. Your success is measured by the stability of your assigned accounts and your ability to minimize the time-to-first-transaction for new partners.
