Modeling and Simulation Engineer

Crossflow Technologies seeks an engineer to support the development, integration, and application of modeling and simulation (M&S) capabilities for hypersonic systems. This role will focus on integrating disparate engineering models and simulation tools into efficient analytical workflows and developing software to automate simulation setup, execution, and post-processing. The engineer will work across software development using C++ and aerospace engineering disciplines to evaluate vehicle performance throughout flight environments and improve the tools and processes used to perform multidisciplinary analysis.

• Integrate, maintain, and enhance M&S tools by connecting standalone engineering models and simulation applications into unified analytical workflows.
• Develop Python-based software, scripts, and automation for simulation setup, execution, data processing, and analysis.
• Generate, evaluate, and optimize hypersonic vehicle trajectories across relevant mission and flight conditions.
• Perform aerothermal analyses to characterize vehicle and system performance throughout hypersonic flight.
• Develop and maintain pre-processing and post-processing workflows for structural, thermal, and aerothermal models.
• Extract, process, visualize, and interpret simulation results to support engineering assessments and design decisions.
• Identify opportunities to improve the efficiency, repeatability, and robustness of multidisciplinary analysis pipelines.
• Design, implement, and maintain CI/CD pipelines to support frequent, reliable software delivery
• Troubleshoot integration, execution, and data-interface issues across engineering models and simulation tools.
• Develop and maintain software using Git Lab, version control, code review, testing, documentation, and other software development best practices.
• Collaborate with multidisciplinary engineering teams to integrate trajectory, structural, and other analysis capabilities.

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related engineering or technical discipline.
• Strong proficiency in Python, particularly for scientific computing, engineering analysis, scripting, or workflow automation.
