2026 Graduate - Mechanical-Fluids Analysis Engineer, Shipboard Systems Team

Job Overview Are you excited by the challenge of performing modeling and simulation and analysis on complex weapon systems in support of the U.S. Navy? Do you have a strong desire to work with data from operational U.S. submarines to understand performance and develop and validate physics‑based models? We are seeking a Mechanical Engineer ready to embrace challenges associated with simulating and analyzing complex submarine missile launcher systems. The ideal candidate has a strong interest and foundation in fluid dynamics and a willingness to apply and expand their skill set across a range of technical challenges. 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. Qualifications Have a Bachelor's or Master's degree in Mechanical Engineering or a closely related field. Have demonstrated interest in fluid dynamics through coursework, professional experience, or laboratory work. Are willing to learn new tools and embrace the changes needed to transform existing workflows in a developing digital engineering environment. Are willing and able to travel occasionally (5%) to U.S. Navy facilities, bases, and contractor sites. Can obtain an interim Secret level security clearance by start date and ultimately obtain a Secret level clearance. Eligibility requires U.S. citizenship. Preferred Qualifications Significant experience performing modeling and simulation using CFD tools such as OpenFOAM, StarCCM+, MATLAB/Simulink, Python, etc. Experience with data analysis of large, complex mechanical systems. Experience working with submarines or missile launcher systems. Active Secret or Top Secret security clearance.
