This position provides an opportunity to build foundational systems engineering experience, including requirements analysis, model integration and testing, and system architecture support, while contributing to a technical team of engineers, analysts, and developers.

This position is contingent upon contract award, and employment will begin upon successful award and authorization to proceed.

ESSENTIAL DUTIES / RESPONSIBILITIES:

• Perform systems engineering analysis, design, integration, testing, documentation, and implementation support activities under the direction of senior engineering staff.
• Support the integration of aircraft subsystem models and associated capabilities into the simulation environment, including analysis of system interfaces, data exchanges, dependencies, and expected system behavior.
• Support senior engineers and stakeholders in the development and documentation of system architectures, designs, functional decompositions, and interface definitions.
• Develop and maintain system architecture models using standards-based modeling languages such as SysML and UML within Model-Based Systems Engineering (MBSE) tools.
• Support system requirements analysis, decomposition, allocation, traceability, and verification coverage to ensure technical requirements are appropriately implemented and tested.
• Participate throughout the system development lifecycle, with emphasis on requirements analysis, model integration, verification and validation, system testing, and acceptance activities.
• Support the development of integration and test plans, procedures, test cases, and associated technical documentation.
• Assist with the execution of integration and test events and analyze test results, system logs, interface behavior, and other technical data to identify and document discrepancies.
• Support troubleshooting and root-cause analysis of system, subsystem, model, and interface integration issues in collaboration with software developers, model developers, test engineers, and senior systems engineers.
• Support evaluation of system interoperability, performance, stability, security, scalability, and other system-level quality attributes.
• Assist with the development and maintenance of Interface Control Documents (ICDs), architecture products, requirements specifications, test documentation, engineering analyses, and other technical artifacts.
• Support configuration management and engineering change activities by assessing proposed changes for potential impacts to requirements, interfaces, models, test activities, and overall system behavior.
• Communicate technical information clearly and professionally and engage effectively with engineering staff, program management, teammates, and DoD customers.

MINIMUM QUALIFICATIONS:

• Bachelor’s degree in Systems Engineering, Computer Engineering, Electrical Engineering, Computer Science, Software Engineering, or a related technical discipline from an accredited institution.
