Ability to Obtain Public Trust

The Quality Assurance System Tester will support a large-scale agile software development program for the Federal Health contract, including both new software capabilities and ongoing support for legacy system functionality. This role will be embedded with software delivery teams to validate application features, integrations, data flows, legacy touchpoints, and release packages throughout the software development lifecycle. The tester will design and execute manual and automated tests, support developer-led quality practices, analyze defects, verify code changes, and help ensure that new and existing system capabilities meet functional, technical, security, accessibility, and operational requirements before production release.

What You Will Do:

We are seeking a Quality Assurance System Tester with strong software testing, test automation, and application validation experience to support the Federal Health software delivery environment. This role will work directly with developers, Product Owners, Scrum Masters, integration engineers, data teams, DevSecOps engineers, vendors, and Federal stakeholders to verify that new software capabilities and supported legacy functionality are reliable, secure, accessible, data-consistent, and ready for incremental release.

The Quality Assurance System Tester will participate across the SDLC by reviewing user stories and technical designs, developing test scenarios, validating software behavior, supporting application and data testing, documenting and retesting defects, and contributing to automated regression testing within CI/CD pipelines. This individual will help strengthen engineering quality, improve release confidence, and reduce production risk across new application components, existing legacy functionality, and system integrations.

Participate throughout the software development lifecycle by reviewing user stories, acceptance criteria, technical designs, data mappings, interface specifications, and release plans to define complete and traceable test coverage.

Design, execute, and maintain manual and automated test cases for application features, integrations, workflows, reports, database changes, regression scenarios, smoke testing, and user acceptance testing.

Develop and maintain automated test scripts, test suites, reusable test data, and regression assets that can be executed consistently across development, test, staging, and release environments.

Perform end-to-end software testing across new application components, supported legacy system functionality, data exchanges, background jobs, user workflows, reporting outputs, and role-based access paths.

Support integration and database testing by validating data persistence, data transformation logic, error handling, access behavior, and downstream processing outcomes.

Document defects clearly with reproducible steps, expected and actual results, test evidence, severity, priority, environment details, and supporting screenshots or logs when appropriate.

Collaborate closely with developers during sprint execution to reproduce defects, analyze logs or test results, validate fixes, clarify expected software behavior, and support code promotion and release readiness decisions.

Integrate automated tests into CI/CD pipelines where appropriate and support automated test execution, results review, failure analysis, test environment coordination, and maintenance of reusable test data.

Support accessibility, security, performance, data quality, and operational readiness testing in coordination with specialized teams and approved program standards.

Contribute to continuous improvement of software quality practices, test automation frameworks, defect management, traceability, release validation, and engineering quality metrics.

What You Will Need:

Must be able to OBTAIN and MAINTAIN a Federal or DoD "PUBLIC TRUST"; candidates must obtain approved adjudication of their PUBLIC TRUST prior to onboarding with Guidehouse. Candidates with an ACTIVE PUBLIC TRUST or SUITABILITY are preferred.

Bachelor's degree required.

Minimum of FOUR (4) years of experience in software quality assurance, software testing, application testing, test automation, systems testing, or related software development lifecycle roles.

Hands-on experience designing, executing, and documenting test cases for application features, integrations, database changes, workflows, regression testing, smoke testing, and user acceptance testing.

Hands-on experience developing, maintaining, and executing automated test scripts using test automation tools, frameworks, scripting languages, or code-based testing approaches.

Experience testing web-based applications, data integrations, interfaces, reports, background processes, and end-to-end business workflows across multiple software environments.

Experience with defect tracking, test management,
