Senior Mechanical Engineer, Hardware Simulation
Johnson & Johnson Innovative Medicine
Summary
Develop, build, and execute finite element analysis (FEA) models using ANSYS to evaluate structural performance, stiffness, stress, deformation, and durability of robotic medical device assemblies and electromechanical systems.
Job description
Derive and simulate innovative designs based on user needs and product requirements.
Perform static, quasi-static, dynamic, linear, nonlinear, modal, and vibration analyses on complex robotic mechanisms, lightweight structures, actuator systems, and motion transmission assemblies.
Analyze and optimize mechanical components and subsystems including motors, gears, lead screws, splines, cams, bearings, pulleys, belts, linear guides, and other precision motion transmission elements.
Conduct thermal and heat transfer analyses to assess thermal management performance of electromechanical hardware and support design decisions during concept, development, verification, and production phases.
Correlate structural, vibration, and thermal simulation results with physical test data, investigate differences between analytical predictions and test outcomes, and improve model accuracy for design validation.
Collaborate with mechanical design, electrical engineering, controls, systems integration, test engineering, manufacturing, quality, and external vendor teams to support development of robotic medical device platforms.
Provide engineering support for design troubleshooting, root-cause investigation, simulation-driven design improvements, risk reduction, and resolution of technical issues during rapid product development cycles.
Prepare simulation reports, engineering documentation, design specifications, and engineering change order materials while supporting safe, robust, reliable designs in an ISO/FDA-regulated medical device development environment.
May telecommute per company's policies (hybrid).
