The Job:

StanleyBlack & Decker is seeking a Principal Mechanism & Multi-Body Dynamics Engineer to support the development of next-generation industrial equipment and drilling tool platforms through advanced simulation, analysis, and model-basedengineering. This roleis responsible forbuilding andvalidatingmulti-body dynamic models of mechanical systems, including drivetrains, linkages, impact mechanisms, rotating assemblies, and motion transmission systems, to improve product performance, durability, and design robustness.

As aLead / Principal - Mechanism & Multi-Body Dynamics Engineer,you'llbe part of our Tools & Outdoor team working as a hybrid employee.You'llget to:

• Develop,maintain, and refine kinematic and dynamic models of mechanical systems using MBD tools such as MSC Adams,MotionSolve,Ansys Motion,RecurDyn, orSimscapeMultibody.

• Perform subsystem and system-level analysis of drivetrains, linkages, gear trains, actuation systems, impact mechanisms, rotating assemblies, and related mechanism-driven hardware.

• Build and integrate flexible body models through FEA-MBD co-simulation workflows using tools such as ANSYS, LS-DYNA, NASTRAN, or RADIOSS.

• Generate load cases, interface forces, joint reactions, torque histories, and transient event data for structural, durability, and fatigue analysis teams.

• Support mechanism-specific modeling for products involving power transmission, motion conversion, latch/lock systems, clutching elements, and high-speed or high-load dynamic events.

• Correlate simulation outputs against bench, subsystem, and full-system physical test data, and update models to improve predictive accuracy.

• Conduct DOE, sensitivity studies, and parametersweepsto optimize mechanism performance and improve robustness across operating conditions.

• Collaborate with mechanical design teams to define assumptions for joints, contacts, friction, damping, stiffness, inertia properties, and boundary conditions.

• Support co-simulation workflows including FMI/FMU-based frameworks and Adams-Simulink co-simulation where plant dynamics influence system behavior.

• Develop scripts and automation tools using Python, MATLAB, or Adams/View macro scripting to improve model setup, post-processing, and reporting.

• Document model assumptions, validation methods, simulation results, and recommendations in a review-ready format for cross-functional stakeholders.
