Job Description:

Role: Mulesoft Tester / Engineer

they need help with automated testing ... handling integration issues .. developing e2e tests ... unit test creation ... and this will move into more engineering / dev work

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.
• 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.

• Qualifications
• 5+ years of experience testing / developing MuleSoft 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).
• 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
• Salesforce Platform knowledge and experience working alongside Salesforce development teams.
• Experience with event-driven integrations and enterprise integration patterns.
• Experience defining integration testing strategies for large-scale platforms.
• Experience in government/federal contracting environments.
