• Design, develop, qualify, and validate equipment and fixtures used for engineering verification, reliability testing, and failure analysis activities.
• Identify technical risks and drive mitigation strategies throughout product development and sustaining activities.
• Analyze complaint, post-market surveillance, manufacturing, and reliability data to identify trends and drive continuous improvement initiatives.
• Create and review engineering drawings and specifications to ensure appropriate dimensioning, tolerancing, manufacturability, and assembly requirements.
• Perform and review tolerance analyses and engineering stack-ups to assess product robustness and manufacturability.
• Provide expertise in GD&T and mechanical system design principles.
• Support design reviews and provide technical guidance to engineers across multiple disciplines.
• Mentor and develop engineers through technical coaching, design reviews, and problem-solving activities.
• Evaluate manufacturing processes including precision machining, injection molding, silicone molding, extrusion, laser welding, ultrasonic welding, bonding, and mechanical assembly methods.
• Support supplier selection, qualification, and technical evaluations, including assessments of manufacturing capability, capacity, process controls, and quality systems.
• Collaborate with regulatory, quality, and clinical teams to support submissions, audits, inspections, and responses to regulatory inquiries.
• Ensure compliance with FDA regulations, international standards, company procedures, Quality Management System requirements, and applicable regulatory requirements.
• Support company initiatives as directed by management and contribute to continuous improvement of engineering processes, product quality, and operational excellence.

Minimum Qualifications:

• Bachelor's degree in Mechanical Engineering, Biomedical Engineering, Manufacturing Engineering, or related engineering discipline.
• 15+ years of progressively increasing engineering responsibility supporting Class II and/or Class III medical devices, including product development, sustaining engineering, verification and validation, manufacturing support, and risk management activities.
• Demonstrated technical leadership of complex cross-functional programs and ability to influence technical decisions without direct authority.
• Strong understanding of FDA Design Controls, 21 CFR Part 820, product lifecycle management, and medical device development processes.
• Experience leading complex technical investigations and root cause analyses.
• Expertise in mechanical design, tolerance analysis, GD&T, materials, manufacturing processes, and assembly methods.
• Experience with risk management principles and methodologies, including FMEA analysis.
• Strong written, verbal, presentation, and technical communication skills.
• Ability to effectively communicate with engineers, management, auditors, regulators, suppliers, and customers.
• Ability to travel approximately 10%, including domestic and occasional international travel.

Preferred Qualifications:
