Prototypes Engineer

About the role

The owns the end to end realization of physical proof points from digital design to verified hardware. This role owns the creation of functional and visual prototypes of parts, mechanical assemblies, and finished devices to validate design intent. The hire will prepare detailed 3D models for prototyping, verifying geometry and adapting designs for the chosen manufacturing technology. You will be responsible for selecting the optimal technology, material, model orientation, and print parameters based on the specific prototype purpose. The role requires performing independent assembly and post-processing of parts after fabrication to ensure they meet functional standards. You will conduct hands on operations such as drilling, cutting threads, sanding, gluing, and installing threaded inserts and fasteners to complete prototype builds. The position involves fabricating simple parts using milling, turning, laser cutting, and other available technologies in the lab. You will identify constructive issues during prototype assembly and provide clear, actionable feedback to designers for iteration. The role participates in device mechanism verification by checking assembly, clearance, geometry, strength, ergonomics, and component accessibility to ensure prototypes function as intended.
