Full Job Description

Description

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.

Preferred Qualifications.

Further, Leidos will only communicate with you through emails that are generated by the Leidos.com automated system – never from free commercial services (e.g., Gmail, Yahoo, Hotmail) or via WhatsApp, Telegram, etc. If you received an email purporting to be from Leidos that asks for payment-related information or any other personal information (e.g., about you or your previous employer), and you are concerned about its legitimacy, please make us aware immediately by emailing us at [email protected].

If you believe you are the victim of a scam, contact your local law enforcement and report the incident to the U.S. Federal Trade Commission.
