Job description

Description

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 PhD in Mechanical Engineering ready to embrace challenges associated with simulating and analyzing complex submarine missile launcher systems. The ideal candidate will have a strong foundation and expertise in fluid dynamics and will have the ability to apply their depth of knowledge across a range of technical challenges.

As a Mechanical Engineer on our team, you will…

• 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

You meet our minimum qualifications for the job if you…

• Have a PhD in Mechanical Engineering or a closely related field.


• Have demonstrated interest in fluid dynamics through coursework, professional experience, or in a laboratory setting.


• 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.


• Are able to obtain an Interim Secret level security clearance by your start date and can ultimately obtain a Secret level clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.

You’ll go above and beyond our minimum requirements if you…

• Have significant experience performing modeling and simulation using CFD tools such as OpenFOAM or StarCCM+, or with bulk volume analysis in MATLAB/Simulink, Python, etc.


• Have experience with data analysis of large, complex mechanical systems.


• Have experience working with submarines or missile launcher systems.


• Have an active Secret or Top Secret security clearance.
