Towson, MD, United States    

Come build something that matters.    

It takes great people to achieve greatness. People with a sense of purpose and integrity. People with a relentless pursuit of excellence. People who care about making things better For Those Who Make The World™. Sound like you? Join our top-notch team of approximately 43,500 diverse and high-performing professionals globally who are making their mark on some of the world’s most beloved brands, including DEWALT®, BLACK+DECKER®, CRAFTSMAN®, STANLEY®, CUB CADET®, and HUSTLER®. 

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 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.    You’ll get to:     • 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. 

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, 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. 

Preferred Qualifications: Mechanism Design Background   • Experience designing or supporting the design of mechanisms, drivetrains, gear systems, linkages, cams, clutches, or actuation hardware. 

• Strong understanding of mechanical packaging, tolerance effects, manufacturability, assembly constraints, and real-world hardware behavior. 

• Ability to translate CAD-based product architecture into efficient and representative simulation models. 

• Experience working directly with product development teams to influence mechanism concept selection, layout decisions, and design tradeoffs. 

• Familiarity with industrial equipment, power tools, drilling tools, or other ruggedized hardware operating in demanding environments. 

Pure Simulation Background   • Deep experience in high-fidelity MBD model development, solver setup, numerical troubleshooting, and model correlation.  • Experience with FEA-MBD coupling, modal reduction techniques, and flexible body generation using ANSYS, LS-DYNA, ABAQUS, NASTRAN, or RADIOSS.  • Familiarity with co-simulation frameworks such as FMI/FMU and Ada
