Journeyman Modeling and Simulation Engineer

Journeyman Modeling And Simulation Engineer

Crossflow Technologies seeks an engineer to support the development, integration, and application of modeling and simulation (M&S) capabilities for a variety of missile 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.

Key Responsibilities

• Integrate, maintain, and enhance M&S tools by connecting standalone engineering models and simulation applications into unified analytical workflows.
• Develop C++ based software, scripts, and automation for simulation setup, execution, data processing, and analysis.
• 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.
• 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.

Required Qualifications

• Bachelor's degree in Aerospace Engineering, Electrical Engineering, or a related engineering or technical discipline.
• Strong proficiency in Python, particularly for scientific computing, engineering analysis, scripting, or workflow automation.
• Strong proficiency in C++ base software scripts for modeling and simulation.
• Experience developing or integrating modeling and simulation tools or engineering analysis software.
• Experience automating simulation workflows, including model configuration, execution, and processing of simulation outputs.
• Understanding of aerodynamics, thermodynamics, heat transfer, and aerothermal effects relevant to high-speed flight.
• Experience analyzing engineering or simulation data and communicating results to technical stakeholders.
• Experience using Git/Git Lab or comparable configuration-management and collaborative software-development tools.
• Ability to troubleshoot technical issues spanning software, simulation models, inputs, outputs, and computational environments.
• Active Secret security clearance

Preferred Qualifications

• Experience generating, analyzing, or optimizing hypersonic vehicle trajectories.
• 3-10 years of relevant software development, modeling and simulation, analysis, or related engineering experience.
• Experience with mesh generation and preparation of models for numerical analysis.
• Experience coupling or integrating multidisciplinary engineering models, such as trajectory, aerodynamics, aerothermal, thermal, and structural models.
• Familiarity with scientific Python libraries and numerical methods used for engineering analysis.
• Experience developing pre-processing and post-processing tools for large or complex simulation datasets.
• Experience creating reproducible and automated engineering analysis pipelines.
• Familiarity with high-performance or distributed computing environments used for computational engineering analysis.
