The ideal candidate will possess a deep understanding of fluid mechanics and numerical methods, writing custom code and running complex simulations and will be responsible for developing new analytical tools with the team, conducting high-fidelity simulations, and reporting results for design and engineering decisions. Primary Responsibilities. ### Code Development Write, test, and deploy new simulation codes and scripts to solve unique engineering problems that off-the-shelf software cannot address. ### CFD Analysis Setup, run, and analyze complex 2D and 3D Computational Fluid Dynamics (CFD) models for various fluid flow and thermal systems. ### Modeling & Simulation Develop robust mathematical and physics-based models to simulate mechanical system behaviors under diverse operational conditions. ### Validation & Verification Correlate simulation results with physical test data to validate and refine computational models. ### Cross-Functional Collaboration Work closely with design and test engineers to provide actionable insights derived from simulation outputs. ### Technical Reporting Document methodologies, code architecture, and simulation results in comprehensive technical reports and briefings. Basic Qualifications. ### Education - Bachelor's degree in Mechanical Engineering, Chemical Engineering, Aerospace Engineering, or a closely related field. (Advanced degree – MS or Ph.D. – is highly preferred). Experience -5+ years of demonstrated professional experience in modeling, simulation, and complex fluid dynamics analysis. ### CFD Expertise - Deep theoretical and practical knowledge of fluid mechanics, heat transfer, and thermodynamics. Proficiency in running complex models using industry-standard tools (e.g., ANSYS Fluent, OpenFOAM, STAR-CCM+) as well as custom environments. Programing skills - Strong proficiency in writing new code for numerical methods and simulation (e.g., C++, Python, Fortran, or MATLAB). ### Analytical Skills - Ability to translate complex physical phenomena into accurate mathematical models and interpret high-volume simulation data. ### Communication - Excellent written and verbal communication skills for technical documentation and cross-team collaboration. U.S. citizenship required. Preferred Qualifications. Advanced degree If you're looking for comfort, keep scrolling.
