About Hark
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.
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.
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.
About the Role
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.
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
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
