Aerospace Modeling & Simulation Engineer II

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. 

Note: US citizenship and an active TS/SCI clearance are mandatory for this position and required for consideration. 

Required: 

• US Citizenship Required with an active or current TS/SCI clearance. 

• Bachelor’s degree from an accredited college/university, in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Mathematics, Physics, or Computer Science.  

• 3 years of professional experience in space systems modeling and simulation, including knowledge of the theory and applications of astrodynamics, remote sensing, spacecraft design, aerospace systems operations, or complex systems integration. 

• Willing to work on-site. 

Desired/Preferred Qualifications: 

• An advanced degree in Engineering or a related field. 

• 7 years of professional experience in space systems modeling and simulation, including knowledge of the theory and applications of astrodynamics, remote sensing, spacecraft design, aerospace systems operations, or complex systems integration. 

• Experience with the design, development and software implementation of complex mathematical algorithms. 

• Ability to develop standalone engineering tools/scripts via Python and/or Excel. 

• Ability to identify, analyze, resolve technical risks and issues, develop technical reports, and collaborate with government and other stakeholders to implement recommended solutions. 

• Ability to communicate and establish collaborative relationships with both clients and teammates to achieve program goals. 

• Strong interpersonal, written, and verbal communication skills. 

• Highly motivated and dynamic work ethic with a strong desire to contribute to the mission.
