About the role

Key responsibilities & impact

The Quality Assurance System Tester will support a large-scale agile software development program for the GrantSolutions 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.
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.
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.
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.
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.

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, requirements traceability, test evidence capture, test data preparation, release validation, and defect retesting.
Understanding of the software development lifecycle, agile delivery, DevSecOps practices, version control, branching and merging concepts, CI/CD pipelines, automated testing, and release management.
Ability to interpret user stories, acceptance criteria, business rules, interface specifications, data mappings, architecture guidance, and technical design documentation.
Ability to troubleshoot test failures, isolate defects, analyze logs, query data when needed, validate fixes, and communicate software quality risks clearly to technical and non-technical stakeholders.
Strong documentation skills, including the ability to maintain test plans, test cases, test scripts, traceability matrices, defect records, test evidence, and release readiness summaries.
Strong problem-solving, collaboration, and communication skills, with the ability to work effectively as part of a software delivery team that includes Product Owners, developers, integration engineers, data teams, DevSecOps engineers, vendors, security teams, and business stakeholders.
Self-motivated, detail-oriented, and able to operate effectively in fast-paced, dynamic environments with competing testing priorities and release timelines.
