Build and enhance aerospace simulation tools, data pipelines, and visualization apps to evaluate space, airborne, and sensor systems for government and commercial customers.
Vantor is forging the new frontier of spatial intelligence, helping decision makers and operators navigate what’s happening now and shape what’s coming next. Vantor is a place for problem solvers, changemakers, and go-getters—where people are working together to help our customers see the world differently, and in doing so, be seen differently. Come be part of a mission, not just a job, where you can: Shape your own future, build the next big thing, and change the world.
To be eligible for this position, you must be a U.S. Citizen. This position requires an active U.S. Government security clearance, applicants who do not currently hold the required clearance will not be eligible for consideration. Employment for cleared roles is contingent upon verification of clearance status.

Vantor is seeking an Aerospace Modeling & Simulation Software Engineer to develop software capabilities that support advanced Intelligence, Surveillance, and Reconnaissance studies for government and commercial customers. In this role, you will build and enhance simulation tools, data processing workflows, analysis applications, and visualization capabilities used to evaluate future space, airborne, and sensor systems.
This is a hands-on technical role for a software developer with an aerospace mindset—someone who enjoys designing practical tools, improving simulation capabilities, working with large technical datasets, and translating complex mission needs into reliable, maintainable software. You will contribute across fast-paced studies and longer-term efforts that help shape the systems and architectures of the future.
Note: U.S. citizenship and an active TS/SCI clearance are mandatory for this position and required for consideration.
What You’ll Do
Design, develop, test, and maintain software tools that support aerospace modeling, simulation, mission analysis, and data visualization.
Add new features and capabilities to high-fidelity physics based simulators used to evaluate space, airborne, and ISR sensor systems.
Design and implement modular, maintainable software architectures that enable new simulation features, reusable analysis workflows, and efficient integration with existing modeling and engineering tools.
Develop scripts, applications, APIs, and data pipelines to support scenario generation, simulation execution, post-processing, analysis, and reporting.
Work with aerospace engineers, analysts, and customers to translate mission needs, study objectives, and operational concepts into software requirements and technical solutions.
Build efficient data processing and visualization workflows for large simulation datasets.
Improve simulator performance, maintainability, usability, automation, and overall workflow efficiency.
Perform debugging, verification, validation, and QA/QC of software tools, simulation inputs, outputs, and analytical results.
Apply modern software engineering practices, including version control, testing, documentation, code reviews, and configuration management.
Collaborate with multidisciplinary teams while also owning independent software development and analysis tasks.
Required Qualifications
U.S. citizenship with an active or current TS/SCI clearance.
Bachelor’s degree from an accredited college or university in Computer Science, Software Engineering, Aerospace Engineering, Electrical Engineering, Mechanical Engineering, Mathematics, Physics, or a related technical field.
5 years experience.
Experience developing software, scripts, tools, or applications in support of engineering, modeling and simulation, data analysis, or mission analysis.
Experience with Python, C++, Java, C#, MATLAB, JavaScript, or similar programming languages.
Familiarity with aerospace systems, space systems, airborne systems, ISR missions, sensors, mission analysis, or simulation environments.
Willingness to work on-site.
Desired/Preferred Qualifications
Advanced degree in Engineering, Computer Science, Mathematics, Physics, or a related technical field.
8 years experience.
Experience developing or modifying modeling and simulation software, engineering analysis tools, mission analysis applications, or simulator frameworks.
Experience designing modular software architectures, reusable components, APIs, or plugin-based capabilities.
Working knowledge of satellites, aircraft, ISR sensors, astrodynamics, remote sensing, aerospace systems operations, or complex systems integration.
Experience with data processing, visualization, algorithm development, numerical methods, statistical analysis, or automated report generation.
Experience with Python data and scientific computing libraries such as NumPy, pandas, SciPy, Matplotlib, Plotly, or similar tools.
