• Support systems engineering activities across the full INCOSE systems lifecycle, from concept development and requirements definition through integration, verification, validation, deployment, and sustainment.

• Apply established systems engineering methodologies, processes, and best practices to support the development and implementation of mission-critical capabilities.

• Develop, analyze, document, and manage system requirements, ensuring alignment with Sponsor mission objectives and operational needs.

• Support system architecture development, technical assessments, and engineering trade studies to evaluate alternative solutions and recommend technical approaches.

• Provide programmatic and technical support to high-visibility Sponsor programs, including planning, execution, coordination, and performance monitoring.

• Support the development and maintenance of systems engineering documentation, including requirements specifications, interface documentation, technical baselines, and lifecycle artifacts.

• Coordinate system integration, verification, and validation activities to ensure solutions meet technical, operational, and performance requirements.

• Conduct technical risk assessments, gap analyses, and feasibility studies to identify potential issues and recommend mitigation strategies.

• Collaborate with Sponsor stakeholders, program managers, engineers, developers, and mission personnel to translate operational needs into actionable technical requirements.

• Support technical reviews, milestone assessments, design reviews, and program status briefings throughout the systems development lifecycle.

• Monitor program progress, engineering deliverables, and technical dependencies to support successful execution of program objectives.

• Apply configuration management, change control, and requirements traceability practices to maintain consistency across system baselines and engineering documentation.

• Evaluate emerging technologies and engineering solutions to identify opportunities for improved system performance, interoperability, and mission effectiveness.

• Communicate complex technical concepts, engineering recommendations, and program risks to both technical and nontechnical stakeholders.

• Support continuous improvement of systems engineering processes, standards, and program execution practices within the Sponsor environment.

Required:

• An active TS/SCI clearance with Full Scope Polygraph (FSP) is required to be considered for this role.

• Bachelor's degree in a technical discipline such as Systems Engineering, Computer Science, Computer Engineering, Electrical Engineering, Information Technology, or a related field.
