Join a collaborative engineering team responsible for producing Integrated Threat Products (ITPs) that replicate real-world adversary capabilities and support mission planning, engineering analysis, testing, training, and operational readiness. A Day in the Life - What you'll do

• Develop high-fidelity missile trajectory models and kinematic data supporting advanced missile defense modeling and simulation environments.
• Analyze customer scenario requests to identify technical requirements, potential modeling challenges, and simulation constraints prior to production.
• Generate end-to-end threat attack laydowns using the Threat Modeling & Simulation Suite (TMSS), accurately representing adversary missile launches, trajectories, and weapon employment.
• Apply knowledge of adversary missile capabilities, tactics, techniques, procedures (TTPs), and strategic objectives to create realistic threat scenarios supporting engineering and training objectives.
• Assign appropriate missile systems and warhead configurations to simulated attack scenarios to accurately model real-world threat behavior.
• Validate modeling outputs through detailed quality reviews, troubleshooting, and technical analysis to ensure customer requirements are fully satisfied.
• Collaborate daily with systems engineers, software developers, and modeling & simulation specialists to improve internally developed simulation tools and capabilities.
• Analyze simulation results and technical data to identify discrepancies, improve model fidelity, and support continuous enhancement of threat products.
• Prepare technical documentation and communicate modeling assumptions, engineering findings, and simulation results to internal teams and government customers.
• Support multiple concurrent projects with varying schedules, balancing rapid-turnaround customer requests alongside long-term engineering efforts.
• Participate in technical reviews, engineering discussions, and collaborative planning supporting Missile Defense Agency testing and operational exercises.
• Support occasional travel (up to 10%) for customer engagement, program collaboration, and mission support activities. Required Qualifications Systems Engineer II
