Senior Mechanical Engineer, Hardware Simulation

Senior Mechanical Engineer, Hardware Simulation

Location: Santa Clara, United States of America

Duties

• 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.

• 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 policies (hybrid).

Requirements

• Master’s degree in Mechanical Engineering or related field and 2 years of experience in the job offered or in a related mechanical engineering role.
• Experience with building complex simulation models with ANSYS and Abaqus to propose solutions for electromechanical systems.
• Vibration analysis, including modal analysis, modal testing, and dynamically induced vibration analysis.
• Experience with static, dynamic, linear, and nonlinear analyses on assemblies ranging from 3 to 60 parts.
• Simulation of motors, gears, lead-screws, splines, cams, linear guides, belts, bearings, and pulleys.
• Crafting static, quasi-static and explicit dynamic models.
• Mechanical analysis including statics, dynamics, kinematics, thermal management, and stress analysis.
• Manufacturing processes and materials including machining, sheet metal, casting, injection molding, and 3D printing.
• Knowledge of drawing standards such as AMSE Y14.5-2009 Dimensioning and Tolerancing.
• Experience working with vendors to select, source, quote, and procure components (off-the-shelf and custom designed).
• Proficiency in Finite Element Analysis (FEA) and thermal simulations.
