Responsibilities:

• Design and implement a comprehensive automated testing strategy for MuleSoft integrations.

• Build and maintain automated integration, API, regression, and end-to-end test suites.

• Build tests that specifically validate bidirectional data flow between Salesforce and external systems — including data transformation logic, retry behavior, and failure/edge-case handling.

• Improve CI/CD pipelines to incorporate automated integration testing.

• Establish testing standards, best practices, and quality metrics (e.g., test coverage %, integration defect rate, MTTR) for enterprise integrations.

• Strong experience integrating Salesforce with external applications, including familiarity with Salesforce API types (REST, SOAP, Bulk, Platform Events) and how Salesforce-side triggers/flows can affect integration timing and behavior.

• Experience managing test data and environments for integration testing, including Salesforce sandbox environments and simulating external dependencies that are unavailable or unsafe to call in test

• Experience building automated API and integration tests (e.g., MUnit, Postman/Newman, REST Assured, Karate, or similar frameworks).
