Contract - Mulesoft Integration Engineer

We are seeking a mid-level Mulesoft Engineer to join one of our client teams on a contract basis through April 2027 with the potential of extension.
This contract is for 35 hours per week. Rate $85 - $93/hour depending on experience. 

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.


• Preferred
