About The Position

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 drivetrains, 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.

Requirements

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, MotionSolve, Ansys Motion, RecurDyn, 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 support structural analysis, fatigue assessment, wear or durability engineering.
Experience correlating simulation predictions with physical test data and improving models based on measured results.
Working knowledge of flexible body modeling and interaction between MBD and finite element representations.
Proficiency in technical scripting or automation using Python, MATLAB, or equivalent tools.
Working knowledge of structured coding languages C#, C++ or equivalent.
Strong problem-solving skills and the ability to work effectively across design, test, and analysis functions.

Responsibilities

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