Senior Automated Test Engineer

Leidos is seeking a Senior Test Automation Engineer to help deliver mission-essential software capabilities that enable intelligence professionals to access critical information, analyze data, and support time-sensitive national security operations.

As a key member of a high-performing Agile team on the Chinook program, you'll use Playwright to build robust automated tests that validate mission-critical user workflows and Bruno and/or Postman to verify the accuracy, reliability, and security of APIs that connect essential systems and data.

Primary Responsibilities:

• Design, develop, execute, and maintain robust automated test scripts using Playwright to validate web application functionality, user workflows, and regression requirements.
• Develop and maintain automated API tests using Bruno and/or Postman to validate RESTful services, request/response payloads, authentication, error handling, and data integrity.
• Build and enhance scalable test automation frameworks that support functional, integration, end-to-end, smoke, and regression testing.
• Integrate automated test suites into CI/CD pipelines to enable continuous testing, rapid feedback, and early defect detection.
• Collaborate with Agile development teams to define acceptance criteria, identify test scenarios, and implement automated testing strategies within each sprint.
• Participate actively in Agile ceremonies, including sprint planning, daily standups, backlog refinement, sprint reviews, and retrospectives.
• Develop and execute comprehensive test plans, test cases, and test scripts based on user stories, functional requirements, and system specifications.
• Perform API validation, including HTTP methods, status codes, JSON payloads, authorization, authentication, and negative testing scenarios.
• Analyze automated test results, troubleshoot failures, identify root causes, and document defects using Agile tracking tools such as Jira.
• Partner with software developers to improve application testability, identify opportunities for earlier testing, and reduce manual regression testing.
• Establish and promote test automation standards, reusable components, and engineering best practices across the development team.
• Support test data management, environment configuration, and test execution across development, integration, and staging environments.
• Provide technical guidance and mentorship to junior test engineers and contribute to continuous improvement of the team's quality engineering practices.
• Ensure testing activities align with customer security requirements, organizational quality standards, and program delivery objectives.

Benefits:

• Pay Range $107,900.00 - $195,050.00

Requirements:

• Active Top Secret/SCI with the ability to successfully pass a Polygraph examination.

• 8+ years of hands-on experience in software test automation, quality engineering, or software development with a strong emphasis on automated testing.
• Demonstrated hands-on experience developing, executing, and maintaining automated UI tests using Playwright.
• Practical experience using Bruno and/or Postman to develop, execute, and validate API tests.
• Strong programming experience with TypeScript and/or JavaScript for test automation development.
• Experience designing and maintaining automated test frameworks for modern web-based applications.
• Strong understanding of RESTful APIs, HTTP methods, JSON, authentication mechanisms, and API validation techniques.
• Experience integrating automated tests into CI/CD pipelines using tools such as Jenkins, GitLab CI/CD, GitHub Actions, or equivalent platforms.
• Experience working on Agile software development teams using Scrum or similar methodologies.
• Experience with source control systems such as Git.
• Demonstrated ability to analyze requirements, develop test scenarios, troubleshoot application issues, and document defects.
• Strong understanding of software testing methodologies, including functional, integration, regression, end-to-end, and negative testing.
• Excellent communication, collaboration, analytical, and problem-solving skills.
• Ability to work independently, manage competing priorities, and deliver high-quality automation solutions in a fast-paced Agile environment.
