About the role

Product Design Engineer role at Hark focused on shaping the physical form of AI-powered devices, spanning concept sketches, CAD modeling, prototyping, and DFM with cross-disciplinary collaboration to design enclosures and mechanisms for complex sensor arrays, thermal systems, and compact compute modules.

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

Qualifications

  • 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
