Product Design Engineer, AI Glasses

Meta Reality Labs is seeking a Principal Product Design Engineer to drive the mechanical and structural design of next-generation AI-powered smart glasses and wearable devices. In this role, you will define the long-term mechanical architecture for AI glasses and wearables, shaping how millions of people experience AI-enabled wearable computing. You will operate at the intersection of industrial design, systems engineering, and manufacturing, setting the technical direction for complex electromechanical assemblies across the full product lifecycle - from concept through mass production.Define and own the long-term mechanical architecture strategy for AI glasses and wearable devices, including frame structures, optical assemblies, and miniaturized subsystems Lead cross-functional alignment across industrial design, electrical engineering, optics, and manufacturing engineering to establish system-level mechanical requirements and design constraints Drive concept generation, feasibility analysis, and down-selection for novel mechanical mechanisms, hinge systems, and form-factor innovations in smart glasses and wearables Establish design standards, tolerance stack-up methodologies, and structural analysis frameworks adopted across the broader mechanical engineering organization Partner with supply chain and contract manufacturing teams to define design-for-manufacturability and design-for-assembly guidelines at scale Lead technical risk identification and mitigation planning for complex electromechanical integrations, including thermal management, sealing, and durability requirements for body-worn devices Provide technical guidance to other engineers on mechanical design decisions, prototype build strategies, and validation approaches for wearable consumer electronics Collaborate with materials science and advanced manufacturing teams to evaluate and qualify novel materials, coatings, and fabrication processes for next-generation AI glasses and wearables Represent mechanical engineering in executive-level design reviews, communicating trade-offs and technical decisions to cross-functional leadership Define and evolve the multi-year mechanical engineering roadmap for AI glasses and wearable hardware, influencing organizational priorities and resource allocation12+ years of experience in mechanical or product design engineering for consumer electronics, wearable devices, or precision electromechanical systems Experience leading system-level mechanical architecture definition for complex, miniaturized hardware products from concept through mass production Experience with tolerance analysis, structural simulation (FEA), and design validation methodologies for wearable or handheld consumer devices Experience driving cross-functional technical alignment across industrial design, electrical engineering, optics, and manufacturing in a hardware product development environment Experience setting organizational-level engineering standards, design guidelines, or technical roadmaps across multiple product generations Track record of filing patents or authoring technical publications in mechanical design, mechanisms, or wearable hardware systems Experience with thermal and structural co-design for compact, body-worn electronic devices with stringent weight and ergonomic constraints Familiarity with advanced manufacturing processes such as injection molding, die casting, CNC machining, and surface finishing as applied to high-volume consumer wearables Experience with optical-mechanical integration, including lens assemblies, camera modules, or precision alignment systems in smart glasses or wearable imaging hardwareMeta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and WhatsApp further empowered billions around the world. Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today-beyond the constraints of screens, the limits of distance, and even the rules of physics.Meta is proud to be an Equal Employment Opportunity employer.
