About The Position

Leidos is hiring a Senior Test Engineer in its Intelligence Sector's Cyber & Analytics Business Area (CABA). The position focuses on designing, building, and maintaining automated test solutions for REST APIs and web-based user interfaces. It requires hands-on experience with Linux command-line tools, Python automation, Docker or Podman, and CI/CD integration using Jenkins and GitLab. The engineer will also help plan and carry out the migration of the in-house automation framework from legacy Robot Framework implementations to a newer platform. The role includes developing automated test suites and maintaining a scalable test harness covering execution, reporting, data setup and teardown, and CI/CD integration. The engineer will contribute to reliable test execution across developer environments and CI pipelines, improve test reporting and stability, and collaborate with engineering and QA stakeholders on framework improvements and release needs. The position requires an active TS/SCI clearance with polygraph.
