Test Engineer – Linux/Bash - 8+ yrs of Experience - TS/SCI w/Poly Clearance

Halogen Engineering Group is looking for a Test Engineer can design, build, and maintain automated test solutions across both 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. The successful candidate will also help evolve our existing in-house automation framework, including planning and executing migration efforts from legacy Robot Framework implementations to newer platforms. This candidate will analyze system requirements and concept of operations documents, acquisition plans, and system descriptions to develop evaluation and test plans and procedures, prepare for and conduct the data collection and analysis, and report status and results. Supports the development of Government test and evaluation documentation e.g., Test & Evaluation (T&E) Strategy, Test & Evaluation Master Plan, Event Test Plans, Test Readiness Assessments, and T&E Reports. Works with other test organizations to support T&E program integration. Provides specialized T&E capabilities tailored to system functions, level, maturity, and performance area as assigned in the SOW.
