Speech Language Pathologist Jobs

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 are looking for an exceptional Electronics Strategic Supply Chain Manager to own the sourcing strategy, commercial execution, and supply readiness for critical electronics used in next-generation AI hardware. This role is designed for a hands-on, high-ownership GSM with experience in high-volume electronics environments, including PCBA, EMS / contract manufacturing, semiconductor and passive components, RF / connectivity modules, flex circuits, and other board-level or module-level technologies. This is a build-and-scale role, not a maintenance role. You will define the electronics supply base, lead strategic sourcing decisions, negotiate commercial agreements, drive cost and capacity outcomes, and ensure suppliers can support aggressive NPI and mass production ramps. You will partner closely with EE, ME, PD, firmware, quality, operations, finance, legal, and manufacturing partners to move technologies from concept and prototype through New Product Introduction and sustained production.
