About The Position

Johnson & Johnson MedTech is seeking a Senior Manufacturing Mechanical Engineer to lead new product and process development and industrialization for advanced robotic medical device systems in Milpitas and Santa Clara, California. The role focuses on surgical robotic structures and instrument drive-end mechanisms, owning the manufacturing engineering lifecycle for electromechanical assemblies that support surgical accuracy, patient safety, and clinical outcomes. The engineer will bridge design intent and manufacturing execution by developing precision assembly, metrology, and validation processes and helping ensure products can be launched and scaled while meeting quality requirements. The position involves designing and validating assembly processes, tooling, gauges, and fixtures; developing manufacturing documentation and readiness frameworks; troubleshooting electromechanical systems; and supporting continuous improvement and production transitions. It requires close collaboration with R&D, Development Engineering, Operations Process Engineering, Quality, and Production. The role also provides technical leadership, coaches junior engineers and technicians, and drives alignment across teams in a fast-paced, changing NPI environment. The anticipated base pay range for this Bay Area position is $111,000 to $178,250. Eligible employees may participate in the company’s consolidated retirement plan and 401(k) savings plan, and may be eligible for vacation, sick time, holidays, personal and family time, parental, bereavement, caregiver, volunteer, and military-spouse leave, subject to applicable plan terms and policies.

Requirements

Bachelor’s and/or Master’s degree in Mechanical Engineering, Mechatronics, Biomedical Engineering, or a related field.
