Principal Engineer, Hardware Simulation | Sunnyvale, CA

to enhance healthcare providers' abilities and improve patients' diagnoses, treatments, and recovery times. Johnson & Johnson Robotics was established in 2020 with the integration of Auris Health, Verb Surgical, C-SATS, and Ethicon. It comprises three key med-tech platforms: Flexible Robotics (MONARCH®), Surgical Robotics (OTTAVA™), and Digital Solutions.

Join our collaborative, rapidly growing teams in the San Francisco Bay Area (Redwood City and Santa Clara), Cincinnati, and Seattle. You'll collaborate on breakthrough medical technologies that unite multiple subject areas to build a connected digital ecosystem that advances medical professionals' skills and improves patient outcomes.

The Principal Mechanical Engineer will work with other members of the Robotics and Digital Solutions team to analyze complex mechanisms, simulate structural but lightweight assemblies, motor driven actuators, and motion transmissions.

This role is responsible for leading simulation analyses through conceptual and detailed FE analysis, related documentation, and design specifications. Your work will be focused on deriving and simulating innovative designs based on user needs and product requirements! Key team interfaces include electrical engineering, robot controls, system integration, testing, external vendors, and internal manufacturing groups. You will contribute to the development

of a complex robotic medical platform. For a self-motivated individual, this is a unique opportunity to jump into the middle of a fast-paced environment passionate about quantitative results and delivery of a platform that exceeds expectations.

Core Job Responsibilities: Demonstrated ability to lead multi-disciplinary simulation analyses and tackle tough problems in innovative ways to deliver unique design solutions for components, products, systems, and equipment Proven experience with complex mechanisms and automation. Expertise in Finite Element Analysis using ANSYS. Proficiency in applying advanced mathematical concepts to analyze and optimize detailed mechanisms.

Build FEA models from scratch, working alongside design engineers across multiple subject areas. Provide hands-on troubleshooting, process, and engineering assistance in support of a rapid development cycle. Strong understanding of vibration analysis, including modal analysis, modal testing, and dynamically induced vibration analysis. Excellent documentation practices with the ability to convey data in a meaningful way. Ability and willingness to work through all phases of product development from conceptualization to production. Design solutions within a quick development cycle, and support those designs with prototype, analysis, and testing results.

Establish and take ownership for subsystem test strategy for root cause analysis and simulation verification. Be a positive, collaborative team member with a good honest work ethic. Collaborate with cross-departmental engineering teams and program management for system development and project planning. Qualifications Masters in Mechanical Engineering (MSME) or equivalent is required. A minimum of 10 years of proven experience building complex simulation models with ANSYS (or equivalent modeling software) is required.

Proficiency with various simulation types: static, dynamic, linear and non-linear analysis on assemblies ranging from 3 to 100 parts is required. Demonstrated excellence in the simulation of motors, gears, lead-screws, splines, cams, linear guides, belts, bearing & pulleys is preferred. Proficiency in crafting static, quasi-static and explicit dynamic models that accurately predict real world testing is required. Mechanical analysis experience including statics, dynamics, kinematics, strength of materials, thermal management, and stress analysis is required. Proven experience understanding manufacturing processes such as machining, sheet metal, casting, injection molding, and 3D printing is preferred.

Capable of making drawings following standard methodologies from AMSE Y14.5-2009 Dimensioning and Tolerancing is preferred. Excellent written & verbal communication and presentation skills are essential. Consistent track record working well in a team environment, learning from others, as well as mentoring and coaching more junior team members is vital. Previous engineering experience in the design and development of medical device robotics or complex electro-mechanical mechanisms and motors is preferred.

Experience working in an ISO and FDA regulated environment is beneficial. The anticipated pay range for this position is 166,000k - 267,145k.
