Contract - Mulesoft Integration Engineer

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.
Identify gaps in existing test coverage and improve overall integration quality.
Troubleshoot integration defects and perform root-cause analysis across Salesforce, MuleSoft, and downstream systems — using findings to close systemic gaps in test coverage, not just fix one-off bugs.
Partner with Salesforce developers, MuleSoft developers, QA engineers, and product teams to ensure reliable deployments.
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.
Document testing patterns and coverage so the broader team can maintain and extend the suite going forward, rather than the knowledge sitting with one person

Required Experience

5+ years of experience developing MuleSoft integrations.
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).
Strong understanding of REST APIs, asynchronous messaging, authentication (OAuth), and error handling.
Experience with CI/CD pipelines and automated deployment processes.
Ability to analyze complex cross-system issues and improve overall platform reliability.
