Truss is a software development consultancy that builds government technology people actually want to use. _Our systems regularly show up in the New York Times, and when we ask our team what they love most about working here, the answer is consistently the same: the people. We’re collaborative, we hold ourselves to high standards, and we care deeply about the craft of making government services work better. We have been a remote-first organization since our inception and are passionate about work-life balance, building impactful teams, and committed to creating environments that encourage collaboration, different points of view, and creative solutioning. _

We are seeking a mid-level Salesforce Certified 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.
• Salesforce certification is preferred

Eligibility:

You must be eligible to work in the U.S. and may be required to pass a federal background check at the discretion of the client/project you are placed on. Truss employees must live and work within the contiguous U.S. Unfortunately, we are unable to sponsor work visas at this time.

Full-Time Employees enjoy full benefits, generous PTO, a co-working budget, an employee effectiveness budget, and company-wide transparency around salaries and career leveling (view the Truss Leveling Guide).
