| Aspect | Associate Computational Fluid Dynamics | Mechanical Engineer |
|---|---|---|
| Required Credentials | Bachelor's in Mechanical, Aerospace, or related field; some roles may require certifications in CFD software | Bachelor's or higher in Mechanical Engineering; licensure may be preferred |
| Work Environment | Research labs, engineering firms, or manufacturing companies focusing on fluid dynamics simulations | Design offices, manufacturing plants, or R&D departments across various industries |
| Employer & Industry Usage | Specialized in fluid flow analysis within aerospace, automotive, or energy sectors | Broader engineering roles across multiple industries including automotive, aerospace, and energy |
While both roles require a strong foundation in engineering principles, Associate Computational Fluid Dynamics specialists focus on fluid flow simulations and software, whereas Mechanical Engineers have a broader scope including design, analysis, and manufacturing. The roles often overlap in industries like aerospace and automotive, but CFD specialists are more specialized in computational modeling.

The Defense Sector at Leidos currently has an opening for an experienced Engineer skilled in modeling and simulation with a strong emphasis on computational fluid dynamics and combustion. 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.
