Quality Assurance Engineer III (Library of Congress)

Ad Hoc LLC is a technology company that empowers organizations to deliver scalable, impactful digital services. The Quality Assurance Engineer III will be responsible for designing, developing, and maintaining test cases, executing various testing types, and collaborating with developers to ensure quality assurance processes are followed throughout the development cycle.

Responsibilities:

• Design, develop, and maintain manual and automated test cases using Selenium, Cypress, and Playwright, contributing to 90%+ automated test coverage targets for all new and modified code
• Execute functional, regression, and accessibility testing every sprint, validating stories against acceptance criteria and blocking merges that fail automated test gates
• Run SonarQube quality gate checks and Axe/pa11y accessibility scans on every merge request, escalating findings that require remediation before story acceptance
• Validate API contracts and backend service behavior using Postman and Rest Assured
• Collaborate with developers during sprint planning to define clear acceptance criteria and test criteria upfront, ensuring the Definition of Done includes automated test coverage and successful test runs
• Participate in CI/CD pipeline instrumentation via GitLab, helping shift quality left so defects are caught at commit time rather than in higher environments
• Develop reusable test scripts and automation frameworks in Java and JavaScript that reduce repetitive manual testing effort across workstreams
• Proactively write exploratory and edge case test scenarios for new functionality, including third-party integrations such as Pay.gov, login.gov, and deposit format validation
• Participate in SAFe ceremonies and contribute to overall program testing strategy across program domains
• Support recruiting efforts by evaluating homework assignments and potentially assisting with interviews

• Working knowledge of accessibility testing tools including Axe and pa11y
• Experience with API testing using Postman and Rest Assured
• Hands-on experience integrating automated tests into CI/CD pipelines using GitLab
• Solid understanding of agile testing methodologies and how QA fits within a SAFe or sprint-based delivery model
• Prior experience with federal agency digital services or government contracting environments
• Experience with performance and load testing tools such as NeoLoad, JMeter, or Taurus
