Contract - Mulesoft Integration Engineer

United States
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 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
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).

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 07/31/2029

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
