We are seeking an experienced Mechanical Design Engineer to lead the design and development of mechanical components and systems for next‑generation consumer electronics and AR/VR products .

The engineer will work in a highly cross‑functional environment , collaborating with electrical engineering, industrial design, firmware, and operations teams to design innovative products that meet performance, reliability, and manufacturability goals.

This role requires strong expertise in CAD design, product prototyping, high-volume manufacturing, and mechanical system integration for compact electronic devices.

• Lead the mechanical designfor a particular component, feature, or system while having end-to-end product developmentunderstanding.
• Contribute to mechanical solutions as part of a highly cross-functional team, working closely with electrical engineering,industrial design, operations, and firmware teams.
• Create detailed 3D models and 2D drawings for enclosures, internal structures, and components using
  
  CAD software (e.g., Creo, UG NX).
• Model, and iteratively refine prototypes and characterization test systems to validate design concepts and performance goals.
• Build and test prototypes to analyze performance, reliability, and durability under various conditions.
• Optimize space constraints, ensuring tight integration of mechanical parts with electrical components
• Work across the fullproduct developmentcycle, from concept to ship.
• Research and evaluate materials (plastics, metals, composites) and manufacturing processes such asinjection molding,CNC machining, or die-casting, to come up with innovative solutions and approaches for next gen products.
• Collaborate and manage work with Asia-based Supply Chain partners to ensure manufacturability, quality, and cost targets are met.
• Troubleshoot assembly, manufacturing, and system level issues throughout the product lifecycle.

• BS in Mechanical Engineeringor related field.
• 8+ years of industry experience in mechanical design.
• Proficiency in 3
  
  DCADsoftware (Creo,Solid Works, UGNX).
• Deep understanding of GD&T (Geometric Dimensioningand Tolerancing), DFM (Design for Manufacturability), and DFA (Design for Assembly).
• Experience in Design for Manufacturability (DFM),Design for Assembly(DFA), statistical tolerance analysis techniques, functionaldimensioning, geometric tolerancing, and 3D/2
  
  DCADproficiency (e.g.,Solid Works, Creo, NX).
• Working knowledge in material properties, such as plastics, metal, adhesive, glass, etc., and selection for consumer products.
• Testing and analysis experience (FEA, Simulation,Design of Experiments, etc.).
• Experience with FEA (Finite Element Analysis) for structural, thermal, or drop testing.
• Hands-on experience and thorough understanding of high-volume manufacturing techniques (stamping, machining,injection molding, casting, etc.).
• Prior experience in consumer electronics or high-volume precision manufacturing.

• 10+ years ofproduct designand development experience of handheld and/or wearable electronics for high volume manufacturing, including full systems ownership.
• MS or PhD in Mechanical Engineering.
• Experience designing handheld and wearable electronics for high volume manufacturing.
• Experience with NXCADsoftware.
• Experience with products cosmetic surface treatments andinterfacingwithindustrial design teams.
• Experience designing for human factors and ergon
