Product Design Engineer

Hark • San Jose, CA

104d • $120,000 - $300,000

About The Position

We're hiring a Product Design Engineer to help shape the physical form of our AI-powered devices. You'll work across the full product development cycle — concept sketches, CAD modeling, prototyping, and DFM — collaborating with electrical and ML engineers to design enclosures and mechanisms that accommodate complex sensor arrays, thermal systems, and compact compute modules.

Requirements

• Bachelor's in mechanical or product design engineering (or similar)
• 7+ years shipping consumer hardware from concept to mass production
• Deep fluency in mechanical CAD (NX preferred), strong GD&T, tolerance analysis, dimensional management, and statistical software (JMP)
• Comfortable with hands-on prototyping and external partners
• Hands-on experience designing for high-volume manufacturing (injection molding, die casting, stamping, CNC machining)
• Proven ability to balance mechanical, electrical, and industrial design trade-offs at the system level
• Direct experience collaborating with external suppliers and contract manufacturers, including onsite factory support
• Comfortable in early-stage product development with ambiguous constraints and open solution space

Nice To Haves

• Masters in mechanical engineering, product design engineering, mechatronics engineering or similar
• Experience in new product architecture & shipping first generation devices in a lead role
• Experience with in-field failure analysis
• Experience integrating complex sensors including microphones & cameras
• Experience integrating displays, audio modules etc.

Responsibilities

• Lead mechanical design of core hardware (enclosures, structural components, flex assemblies, interconnects) from concept to production
• Convert industrial design intent into reliable, manufacturable, and precise engineering solutions, maintaining product vision and structural/functional performance
• Define and own specifications, tolerances, material selections, and 3D CAD across processes like injection molding, die casting, stamping, and CNC machining
• Drive Design for Manufacturability (DFM) and Design for Assembly (DFA) with manufacturing partners from early concept through production builds
• Use tolerance analysis, FEA, and DOE's to validate designs and resolve failure modes pre-assembly
• Collaborate with Industrial Design, Electrical Engineering, Acoustic Engineering, Reliability & Operations to unify design considerations (functionality, thermal management, human factors, reliability, cost, and aesthetics)
• Build functional prototypes in-house and travel to manufacturing facilities to support builds and resolve issues

Benefits

• The US base salary range for this full-time position is between $120,000 - $300,000 annually.
• The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience.
