About the role

Prototyping Engineer specializing in mold design, casting and molding to accelerate hardware product development. Focus on prototype ideation, early-to-mid stage development, and creating fast prototypes using silicone, urethanes, foams, CNC, 3D printing, and other fabrication methods within Meta's Proto Make Team.

Responsibilities

  • Complex casting & molding: Independently run the lab's most demanding casting and molding projects in silicones, urethanes, resins and foams, mixed, degassed, cast and cured to spec. Finish cast prototypes to rigorous cosmetic standards. Partner with the Casting and Molding leads on the hardest new problems, adding specialist capacity and redundancy to a critical function
  • Mold design & construction: Design and build 3D printed and traditional molds, including multi-part and complex geometries. Design and adapt molds, fixtures and model components in Autodesk Fusion instead of only building to spec
  • Complete models: Take designs from concept to finished physical model, pulling in CNC, 3D printed and 2D cut parts and using both internal and external manufacturing. Bring core model making skills: high-quality finishing, part prep, scratch building, color mixing and strong material knowledge
  • Soft goods prototyping: Quickly explore cast soft components for products worn on the body. Work with Industrial Design, Engineering and Research to solve complex design and UX problems and shape early design decisions
  • Fast, parallel iteration: Manage multiple concurrent projects by prioritizing work based on impact, deadlines, and stakeholder needs, keeping parts flowing for fast design cycles
  • Process improvement & documentation: Try new materials and methods, then turn what works into standard tooling, SOPs and workflows so the function can scale. Build and maintain a knowledge base and clear teaching docs for molding, casting, finishing and material handling
  • Mentorship: Share best practices and give hands-on guidance to team members and CW staff, helping new people ramp up on core skills and lab safety
  • Lab organization: Keep the lab clean and organized and keep improving it. Own inventory, housekeeping, materials ordering and digital workflow and inventory records

Qualifications

  • Bachelor in Fine Arts, Engineering, Design, Materials or related field and/or equivalent practical experience
  • 6+ years of experience in prototype fabrication, model making, or casting and molding for hardware product development
  • Proven experience designing and constructing molds, including the ability to independently own a model build end-to-end, incorporating components from CNC machining, 3D printing, and 2D cutting
  • Demonstrated skill using at least one major CAD tool (Autodesk Fusion, NX, SolidWorks, Rhino)
  • Finishing skills sufficient to bring your own cast and molded parts to spec — sanding, part preparation, and cosmetic cleanup with a high attention to detail
  • Experience maintaining lab organization, materials inventory, and consumable ordering for a shared fabrication space
  • Able to work independently and collaboratively in a fast-paced prototyping environment, managing concurrent projects against hard deadlines
