Senior Test Automation Engineer

About This Role

Seeking a Senior Test Automation Engineer to design, build, and maintain automated test solutions across back-end services (REST APIs) and web user interfaces. This role requires strong hands-on engineering skills in Linux command-line tooling, Python-based automation, containerized test execution (Docker/Podman), and CI/CD integration using Jenkins and GitLab pipelines. You will help evolve the existing in-house automation framework, including planning and executing migration efforts from legacy Robot Framework implementations to newer platforms, and analyze system requirements to develop test plans and procedures.

Responsibilities

• Develop, maintain, and enhance automated test suites for back-end REST APIs and web-based user interfaces
• Build and maintain a scalable, reliable test automation harness (framework) including execution, reporting, data setup/teardown, and CI/CD integration
• Implement and expand Python-based test automation using Pytest, including fixtures, test data strategies, and robust assertions/validation
• Create and maintain Docker/Podman container images used to run automation consistently across developer environments and CI pipelines
• Integrate automated test execution into Jenkins and GitLab CI/CD pipelines, ensuring repeatable runs, clear reporting, and actionable results
• Use Linux command-line tools and Bash shell scripting to locate, parse, transform, and report on large volumes of logs, test output, and system data
• Support UI automation using Robot Framework and the Python Selenium library, including test stability improvements and best practices
• Plan, estimate, and break down work for migrating the in-house test harness from legacy Robot Framework to a modern alternative (e.g., Robot Framework AIO or Microsoft Playwright)
• Maintain SQL queries and integrate database validation steps into automated tests were appropriate
• Troubleshoot CI failures and test irregularity/volatility, improve test reliability, and contribute to continuous improvement
• Apply knowledge of T&E concepts

Requirements

• TS/SCI with a Current CI polygraph
• Strong experience with Linux and Bash shell scripting, with demonstrated ability to work effectively from the command-line and process/report on large data sets (logs, test artifacts, results)
• Advanced experience building test automation in Python, including Pytest-based frameworks
• Strong experience with Docker (or Podman) including building, versioning, and maintaining images used in automation and CI/CD workflows
• Working knowledge of Jenkins and GitLab pipelines, including running containerized workloads and managing automated test stages
• Experience with REST API testing, including validation of responses, authentication flows, and negative/error-path testing
