| Aspect | Python Mechanical Engineer | Mechanical Design Engineer |
|---|---|---|
| Required Skills | Python programming, mechanical engineering fundamentals | Mechanical design, CAD software, engineering principles |
| Work Environment | Software development teams, engineering labs | Design offices, manufacturing facilities |
| Certifications | Optional Python or software certifications, engineering licenses | Professional Engineer (PE), CAD certifications |
| Industry Usage | Automation, robotics, simulation | Product design, machinery, structural components |
The main difference between a Python Mechanical Engineer and a Mechanical Design Engineer lies in their focus areas. Python Mechanical Engineers combine programming skills with mechanical engineering knowledge to develop automation and simulation tools, while Mechanical Design Engineers focus on creating physical product designs using CAD software. Both roles are essential in engineering projects but serve different functions within the industry.

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.
