Product Design Engineer

<p><strong>About Hark</strong></p> <p>Hark is an artificial intelligence company building advanced, personalized intelligence. One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory.</p> <p>We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines. While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world.</p> <p>To get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems.</p> <p><strong>About the Role</strong></p> <p>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.</p> <p><strong>Responsibilities</strong></p> <ul> <li>Lead mechanical design of core hardware (enclosures, structural components, flex assemblies, interconnects) from concept to production</li> <li>Convert industrial design intent into reliable, manufacturable, and precise engineering solutions, maintaining product vision and structural/functional performance</li> <li>Define and own specifications, tolerances, material selections, and 3D CAD across processes like injection molding, die casting, stamping, and CNC machining</li> <li>Drive Design for Manufacturability (DFM) and Design for Assembly (DFA) with manufacturing partners from early concept through production builds</li> <li>Use tolerance analysis, FEA, and DOE's to validate designs and resolve failure modes pre-assembly</li> <li>Collaborate with Industrial Design, Electrical Engineering, Acoustic Engineering, Reliability &amp; Operations to unify design considerations (functionality, thermal management, human factors, reliability, cost, and aesthetics)</li> <li>Build functional prototypes in-house and travel to manufacturing facilities to support builds and resolve issues</li> </ul> <p><strong>Requirements</strong></p> <ul> <li>Bachelor's in mechanical or product design engineering (or similar)</li> <li>7+ years shipping consumer hardware from concept to mass production</li> <li>Deep fluency in mechanical CAD (NX preferred), strong GD&amp;T, tolerance analysis, dimensional management, and statistical software (JMP)&nbsp;</li> <li>Comfortable with hands-on prototyping and external partners</li> <li>Hands-on experience designing for high-volume manufacturing (injection molding, die casting, stamping, CNC machining)</li> <li>&nbsp;Proven ability to balance mechanical, electrical, and industrial design trade-offs at the system level</li> <li>Direct experience collaborating with external suppliers and contract manufacturers, including onsite factory support</li> <li>Comfortable in early-stage product development with ambiguous constraints and open solution space</li> </ul> <p><strong>Bonus Qualifications</strong></p> <ul> <li>Masters in mechanical engineering, product design engineering, mechatronics engineering or similar</li> <li>Experience in new product architecture &amp; shipping first generation devices in a lead role</li> <li>Experience with in-field failure analysis</li> <li>Experience integrating complex sensors including microphones &amp; cameras</li> <li>Experience integrating displays, audio modules etc.</li> </ul> <p><strong>Compensation</strong></p> <p><span data-sheets-root="1">The US base salary range for this full-time position is between $120,000 - $300,000 annually.</span></p> <p>The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience.
