• Serve as a technical lead for systems and software integration in support of Development Test (DT) and Formal Test execution on the SkyLine-X KN-2 program.
• Integrate complex systems and software with minimal oversight, and debug system-level issues while providing detailed supporting data on identified issues.
• Develop and maintain test approach and procedures derived from system-level requirements (A-Level, SSS), including system-level and component-level test procedures, test cases, and data sets.
• Conduct root cause analysis and defect resolution in coordination with software and systems engineering teams.
• Execute integration testing of distributed, safety-critical systems using containerized or virtualized environments (e.g., Docker, Podman), and manage VMs and dev containers.
• Develop and maintain test artifacts and documentation, including the Verification Requirements Test Matrix (VRTM), traceability matrices, and test reports.
• Interface with SkyLine-X software, systems engineering, and integration/logistics teams in support of installation and integration efforts.
• Clearly communicate and generate briefings to report status to both internal and customer stakeholders, and support test readiness reviews and system qualification events.
• Actively participate in daily stand-ups, Sprint Planning, Release Planning, and other Agile team activities.
• Work overtime, off hours, or weekends if necessary to meet deadlines, and be able to support travel.

Qualifications:

• Bachelor's degree in Computer Science, Engineering, Information Systems, or a related technical discipline with 8+ years of relevant experience, or 6+ years with a related Master's degree.
• Experience integrating and testing large-scale, distributed software systems.
• Strong Linux/UNIX administration and troubleshooting experience.
• Experience with Python, Bash, or Shell scripting for automation and data analysis.
• Experience troubleshooting network configurations, connectivity, and distributed system interfaces.
• Experience developing automation solutions that improve engineering efficiency.
• Demonstrated experience in testing, test framework development, and system-level verification of complex or safety-critical systems.
• Systems Engineering experience, including proven experience working on complex projects gathering user requirements and converting them into system requirements.
• Proficiency with scripting languages.
• Experience with Linux or Unix-based environments, containerization (Docker, Podman), and CI/CD pipelines.
• Technical leadership experience in a role requiring significant coordination across multiple functional areas.
• Excellent verbal and written communication skills, including experience working directly with customers to discuss requirements and objectives.
• Strong analytical and problem-solving skills, with the ability to work effectively in a team environment.

Desired Skills:

• Experience integrating mission-critical or highly available systems.
• Air Traffic Management domain experience.
• Familiarity with requirement decomposition to develop A-Level test approach and procedures.
• Familiarity with the Atlassian Tool Suite and JIRA.
• Familiarity with Model-Based Systems Engineering (MBSE) and system integration V&V processes.
• Knowledge of microservices architectures, message brokers, RESTful API testing, and Chaos Testing principles.
• Knowledge of test tools (e.g., Selenium, Sikuli, Squish) and simulation or test-harness frameworks.
• Familiarity with NextGen Air Traffic Control modernization programs.
• Experience preparing and executing Verification Cross Reference Matrices (VCRM) and Test Readiness Review (TRR) documentation.
