Job description

The Junior Systems Engineer supports the engineering team in the development, integration, and testing of aircraft subsystem models within a simulation environment, working under the guidance of senior engineering staff. 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.

If you are a current incumbent on the contract and are unsure which position best aligns with your current role, please apply to the position you believe is the closest match. Our team will review your application and make any necessary adjustments to ensure alignment with the appropriate position.

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.
