Responsibilities

Lead end-to-end design and development of articulating surgical instruments with multiple degrees of freedom for endoluminal applications, from concept through clinical validation and manufacturing transfer

Drive innovation in mechanism design for miniaturized articulating joints, cable-driven actuation systems, and force transmission architectures that maintain performance through tortuous anatomical pathways

Establish design requirements by collaborating closely with surgeons, clinical specialists, and product management to translate surgical needs into rigorous engineering specifications

Architect instrument systems that integrate seamlessly with robotic control platforms, including mechanical interfaces, sensor integration for force and position feedback, and compliance mechanisms for safe tissue interaction

Develop and execute comprehensive testing protocols including bench testing, cadaveric studies, and design verification activities to demonstrate safety, efficacy, and reliability under physiological conditions

Mentor and provide technical leadership to a multidisciplinary team of mechanical, electrical, and software engineers working on instrument development

Drive resolution of complex technical challenges involving material selection, sterilization compatibility, biocompatibility, fatigue life, and manufacturing feasibility for precision miniaturized components

Contribute to intellectual property development through patent disclosures and support regulatory submissions including design history files, risk analyses, and technical documentation for FDA 510(k) or PMA pathways
