The Job:

Stanley Black & 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-based engineering. This role is responsible for building and validating multi-body dynamic models of mechanical systems, including drive trains, linkages, impact mechanisms, rotating assemblies, and motion transmission systems, to improve product performance, durability, and design robustness.

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

• Develop, maintain, and refine kinematic and dynamic models of mechanical systems using MBD tools such as MSC Adams, Motion Solve, Ansys Motion, Recur Dyn, or Simscape Multibody.
• Perform subsystem and system-level analysis of drive trains, 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 parameter sweeps to 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.

The Person:

You love to learn and grow and be acknowledged for your valuable contributions. You're not intimidated by innovation. Wouldn't it be great if you could do your job and do a world of good? In fact, you embrace it. You also have:

• Master's or Ph.D. degree in Mechanical Engineering, Aerospace Engineering, Applied Mechanics, Engineering Mechanics, or a related technical field.
• Typically 5+ years of relevant experience in mechanism analysis, multi-body dynamics, or simulation of mechanical systems; advanced degree may offset a portion of experience.
• 10+ years of relevant CAE experience in product development
• Demonstrated experience with one or more commercial MBD tools such as MSC Adams, Motion Solve, Ansys Motion, Recur Dyn, or Simscape Multibody.
• Strong fundamentals in rigid body dynamics, kinematics, Lagrangian mechanics, constraint systems, contact mechanics, and force element modeling.
• Experience developing models for mechanical systems with multiple moving bodies, joints, contacts, and nonlinear interactions.
• Experience creating simulation outputs that…
