Mechanical Engineer

Engineer Skilled In Modeling And Simulation

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.

• 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.

• 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.
• Programming skills
