Posted on Dec 6, 2024
We are seeking an innovative and highly motivated Mechanical Engineer who will contribute significantly to developing our advanced cell therapy manufacturing platform. The primary focus of this position will be the design, prototyping, production, and verification of highly complex plastic injection-molded consumable assemblies.
As a Principal Mechanical Engineer (consumables), you will be responsible for component selection, design tasks, manufacturing coordination, sterilization coordination, and initial quality assurance efforts of both individual components, and finished assemblies. Additionally, you will be required to provide in-depth analysis and CAD data to help guide important decisions during design reviews.
This is a multidisciplinary role, and this individual will further interface across many parts of the company to develop novel products used in cell therapy and gene therapy. The successful candidate will be experienced in plastic injection molding, material selection, and component selection for complex biomedical consumable device design. This is a hands-on position.
Candidates should enjoy working in a fast-paced, mission-driven environment and be prepared to tackle a broad selection of challenges as the company grows.
