Job description
Valencia, California | Hybrid
Join Advanced Bionics, a Sonova Group company, as a Principal Mechanical Engineer and help develop innovative cochlear implant systems and body-worn medical devices that improve the lives of people with hearing loss.
In this role, you will provide technical leadership throughout the mechanical product-development lifecycle—from requirements and concept development through prototyping, verification, validation, manufacturing and market introduction. You will also mentor less-experienced engineers and collaborate with multidisciplinary teams, suppliers, consultants and members of the medical community.
Responsibilities
•
Lead the mechanical design and development of external and implantable systems and their associated components.
•
Develop products from initial concept through prototyping, manufacturing and commercial introduction.
•
Establish product requirements, technical specifications and mechanical design solutions.
•
Create and maintain 3D CAD models, engineering drawings, tolerance-stack analyses, design specifications and technical reports.
•
Apply design-for-manufacturing principles and structured product-development methodologies.
•
Lead make-versus-buy and fabrication decisions in collaboration with internal teams and external suppliers.
•
Ensure designs comply with functional requirements, internal procedures, quality-system requirements, industry standards and regulatory expectations.
•
Plan and support design-of-experiments, component testing, product testing and verification and validation activities.
•
Lead mechanical failure investigations and support root-cause analysis and corrective actions.
•
Support sustaining-engineering activities throughout the product lifecycle.
•
Establish and maintain Design History File documentation and participate in formal design reviews.
•
Ensure compliance with FDA and ISO design controls and documentation requirements.
•
Collaborate with suppliers on technical requirements, component development, tooling and manufacturing readiness.
•
Work with consultants, vendors and members of the medical and cochlear implant communities.
•
Provide technical guidance regarding technology partnerships, supplier relationships and intellectual property.
•
Plan, coordinate and execute engineering activities in support of project objectives.
•
Build and maintain knowledge of evolving clinical needs, product use cases and market requirements.
•
Mentor and coach engineers while providing cross-functional technical leadership within a core-team environment.
•
Perform other duties and responsibilities as assigned.
Qualifications
•
Bachelor’s degree in Mechanical Engineering, Biomedical Engineering or a related engineering discipline.
•
Eight or more years of mechanical or microelectronic product-development experience.
•
Experience developing complex electromechanical products from concept through production.
•
Experience designing miniature mechanical components, plastic and metal enclosures, microelectronic packages, connectors, cables, antennas, electrical contacts or switches.
•
Knowledge of plastic-part design, injection molding, materials selection and manufacturing processes.
•
Knowledge of conductors, polymers, silicone, adhesives, coatings and biocompatibility requirements.
•
Experience creating 3D CAD models, engineering drawings and tolerance analyses.
•
Working knowledge of verification and validation, design controls and Design History File requirements.
•
Strong analytical, problem-solving and mechanical failure-analysis skills.
•
Demonstrated ability to lead technical work and mentor junior engineers.
•
Strong communication, organization, collaboration and presentation skills.
•
Ability to manage multiple priorities and meet project deadlines in a cross-functional environment.
•
Proficiency with Microsoft Office 365, PLM/PDM systems and ProEngineer/Creo or comparable CAD software, such as SolidWorks.
•
Ability to travel approximately 15%.
Preferred Qualifications
•
Master’s degree in Mechanical Engineering, Biomedical Engineering or a related field.
•
Medical-device product-development experience.
•
Experience with cochlear implants, hearing aids, wearable technology or consumer audio products.
•
Experience with finite element analysis, statistical analysis and Failure Mode and Effects Analysis.
•
Experience designing tooling and fixtures.
•
Experience using MS Project, Moldflow, ANSYS or Minitab.
Compensation
The target base salary range for this position is $131,560–$164,450 annually.
A career at Advanced Bionics offers an opportunity to work with innovative technology and collaborate with talented colleagues who share a commitment to helping people experience the joy of hearing.
