Vantor is seeking an Aerospace Modeling & Simulation Engineer II to support advanced ISR studies for government and commercial customers. In this role, you will model satellites, aircraft, sensor systems, mission scenarios, and operational concepts to evaluate performance, explore trade-offs, and inform decisions on future space and airborne capabilities.
This is a hands-on technical role for an experienced engineer who can independently solve complex mission problems, improve simulation capabilities, and turn detailed analysis into clear recommendations. You will own major analysis tasks, coordinate with technical stakeholders, and contribute to the development of reusable tools and consistent modeling practices.
What You’ll Do
Independently develop, modify, and run high-fidelity simulations of space, airborne, and ISR sensor systems for architecture studies, system trades, performance assessments, and mission-level analyses.
Design operational vignettes and analysis plans that translate customer priorities into measurable scenarios, assumptions, and evaluation criteria.
Own complex analysis tasks from requirements clarification through model configuration, execution, interpretation, and delivery.
Develop new tools, scripts, simulator features, and reusable scenario components to improve scenario generation, data analysis, visualization, and workflow efficiency.
Analyze results to identify trends, risks, trade-offs, sensitivities, and key performance drivers, and provide defensible recommendations.
Apply and improve QA/QC, verification, validation, configuration-management, and documentation practices.
Estimate technical effort, identify risks and dependencies, and coordinate assigned work with project leads and multidisciplinary teams.
Present findings and recommendations to technical teams, program leaders, and customers.
Provide technical guidance and peer review to less-experienced analysts.
