Modeling & Simulation Engineer II/III

About the role

Textron Systems Weapon Systems is seeking a full-time Modeling & Simulation Engineer with experience in structural and dynamic simulation, preferably using LS-DYNA, to support advanced weapon system development programs in Wilmington, MA.

This position requires that the candidate be a U.S. citizen with, or capable of receiving, a Secret level security clearance.

Responsibilities

• Developing and executing high-fidelity structural, dynamic, and impact simulations using finite element analysis (FEA) tools, with LS-DYNA preferred.
• Building, validating, and maintaining physics-based models to predict weapon system performance across a range of operational and environmental conditions.
• Conducting trade studies and parametric analyses to support design decisions and system optimization.
• Correlating simulation results with physical test data to validate and improve model fidelity.
• Generating simulation-based predictions in support of system qualification, certification, and proposal activities.
• Preparing detailed technical reports, model documentation, and analysis presentations for internal teams and customers.
• Collaborating with mechanical, systems, and test engineers throughout all phases of product development.
• For Level III: Leading M&S efforts on complex programs and providing technical guidance to junior engineers.

Qualifications

• Demonstrated experience in computational mechanics and structural simulation applied to defense or aerospace hardware.
• BS or MS in Mechanical Engineering, Aerospace Engineering, or a related technical discipline with at least 2 years (Level II) or 5 years (Level III) of relevant experience.
• Proficiency with at least one FEA software package; LS-DYNA experience strongly preferred. ANSYS or ABAQUS also considered.
• Strong understanding of structural mechanics, material behavior, and failure modes under dynamic and impact loading.
• Experience with explicit dynamic or terminal ballistics simulations is a plus.
• Familiarity with DoD acquisition processes and MIL-SPEC/MIL-STD standards is a plus.
• Possesses or has the ability to obtain a Secret level security clearance.
