Vantor is seeking a Senior Aerospace Modeling & Simulation Engineer 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 senior technical role for an engineer who can lead complex modeling and simulation efforts, serve as a trusted technical intermediary with customers, and guide teams from mission need through defensible recommendations. You will shape analysis approaches, lead technical workstreams, strengthen common practices, and mentor less-experienced analysts.
What You’ll Do
Lead high-fidelity modeling and simulation efforts for complex space, airborne, and ISR architecture studies, system trades, performance assessments, and mission analyses.
Engage customers and program leadership to clarify mission needs, shape technical solutions, and translate objectives into analysis plans, priorities, and executable work packages.
Define technical approaches, assumptions, measures of performance and effectiveness, scenario designs, and acceptance criteria for major workstreams.
Maintain technical quality for assigned efforts through rigorous review of models, inputs, assumptions, methods, outputs, conclusions, and limitations.
Standardize simulation workflows and advance common modeling approaches, reusable scenario components, automation, verification and validation, and technical documentation.
Guide efficient execution of large simulation campaigns, including effective use of cloud, distributed, and high-performance computing resources.
Lead interpretation of complex results, identify cross-project risks and capability gaps, and deliver clear, defensible recommendations to customers and senior decision-makers.
Plan and prioritize technical work, coordinate multidisciplinary contributors, and advise program leadership on scope, schedule, staffing, and technical risk.
Lead technical reviews, mentor junior analysts, and promote knowledge sharing and consistent engineering practices.
Identify opportunities for future investment in ModSim tools, infrastructure, methods, data, and workforce capabilities.

Bachelor’s degree from an accredited college/university, in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Mathematics, Physics, or Computer Science.
8+ 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.
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.
