About The Position

This role involves performing modeling, simulation, and analysis on complex weapon systems for the U.S. Navy, specifically focusing on submarine missile launcher systems. The engineer will work with data from operational U.S. submarines to understand performance and develop physics-based models. The position requires a strong interest in fluid dynamics and offers the opportunity to apply and expand skills across various technical challenges. The team supports sponsors in developing advanced analysis methods, modernizing Navy hardware, and integrating new weapon systems. The engineer will gain deep technical expertise in submarine launcher and shipboard systems, assess the impact of modifications on the underwater missile launch fluid environment, and work with a multidisciplinary team.

Requirements

Bachelor's or Master's degree in Mechanical Engineering or a closely related field.
Demonstrated interest in fluid dynamics through coursework, professional experience, or in a laboratory setting.
Willingness to learn new tools and embrace changes in a developing Digital Engineering environment.
Willing and able to travel occasionally (5%) to U.S. Navy facilities, bases, and contractor sites.
Ability to obtain an Interim Secret level security clearance by the start date and ultimately obtain a Secret level clearance.
U.S. citizenship is required for security clearance eligibility.

Nice To Haves

Significant experience performing modeling and simulation using CFD tools such as OpenFOAM or StarCCM+.
Significant experience with bulk volume analysis in MATLAB/Simulink, Python, etc.
Experience with data analysis of large, complex mechanical systems.
Experience working with submarines or missile launcher systems.
An active Secret or Top Secret security clearance.

Responsibilities

Develop deep technical expertise in submarine launcher and other shipboard systems by analyzing operational patrol data.
Perform Computational Fluid Dynamics (CFD) modeling, including mesh creation, execution, and post-processing on our in-house High-Performance Computing (HPC) cluster.
Perform physics-based bulk volume modeling and data analysis using MATLAB/Simulink and other tools.
Implement coding best practices and develop streamlined, maintainable workflows across the team's modeling and analysis tools.
Validate simulations against test data to assess the accuracy and fidelity of the simulations.
Support test and evaluation efforts ranging from small-scale lab tests to full-scale system tests at government facilities or onboard Navy platforms.
Provide critical technical recommendations to sponsors regarding design solutions proposed by industry partners.
Prepare technical reports and briefing materials for presentation to internal staff, government, and industry partners.
