This is a hands-on opportunity to help integrate, verify and validate an advanced software-based ground system supporting critical national-security missions. You will work alongside systems, software, hardware, DevOps and test engineers to integrate new capabilities, automate system testing, troubleshoot technical issues and help deliver reliable solutions across the development lifecycle. If you enjoy working directly with complex systems-executing tests, analyzing failures, writing automation scripts and helping engineering teams solve difficult integration problems-this role offers an opportunity to make a meaningful technical contribution. What You'll Do Support the development and delivery of advanced ground-system capabilities as part of a cross-disciplinary engineering team. Perform system integration, verification and validation activities within the Systems domain. Work as a member of an Agile Release Train in a collaborative, cross-functional program environment. Develop system-level test plans, procedures and automated test scripts. Execute functional, integration, regression and verification testing. Evaluate software functions, system behavior and internal and external interfaces. Help develop and maintain test environments that support system verification. Identify technical issues during software and hardware integration. Troubleshoot and debug system-level failures in Red Hat Linux environments. Analyze logs, test results and system behavior to isolate the source of defects. Partner with software, systems, hardware and DevOps engineers to develop and implement solutions. Verify corrective actions and help ensure reliable system performance across releases. Collaborate with program customers and engineering stakeholders throughout the integration and test lifecycle. Contribute to Agile planning, execution, demonstrations and continuous improvement., In this position, you will do more than execute predefined tests. You will help determine how complex capabilities should be integrated and verified, build automation that improves testing efficiency, investigate challenging system behavior and work with engineering teams to carry solutions through resolution. You will join a technically sophisticated program where system reliability, disciplined engineering and mission success matter. Why Legion Technical Solutions? Legion Technical Solutions connects accomplished technical professionals with consequential aerospace and defense programs. We value technical competence, professional integrity, clear communication and engineers who take ownership of difficult problems. If you are a cleared integration and test engineer with experience in Linux-based mission systems, automated testing and complex troubleshooting, we invite you to apply.
