Bring your experience and passion for engineering to Lockheed Martin, and build the systems which support our nation's defense systems. This requisition is used to capture interested candidates in opportunities at Lockheed Martin. You can’t and will not be hired on this requisition. Actual job responsibilities, levels, and locations will vary based on actual hiring job postings. What does this role look like? We are seeking a highly motivated Multi-Body Dynamics Engineer to join our team. This role supports the analysis, modeling, and simulation of complex mechanical systems for advanced aerospace and defense applications. The selected candidate will apply rigid and flexible body dynamics principles to evaluate system performance, predict loads and environments, and inform design decisions across the product lifecycle. This position requires close collaboration with design, structural analysis, systems engineering, and test teams to ensure mechanical systems meet performance, reliability, and mission requirements. The ideal candidate brings strong analytical capability, hands-on modeling experience, and the ability to translate dynamic behavior into actionable engineering insight.

Requirements
