Job Description
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 You'll own critical pieces of the firmware stack that powers Hark's consumer products - from board bring-up and peripheral drivers to the runtime environment that hosts on-device intelligence. This isn't firmware in a vacuum. You'll work directly with the hardware team on new silicon and sensor integrations, with the agent team on model execution and memory constraints, and with products on experiences that ship to real users. The problems are real, the constraints are tight, and the work matters immediately. Responsibilities Develop and maintain embedded firmware in C/C++ targeting ARM-based SoCs and microcontrollers Own BSP development, peripheral driver integration (SPI, I2C, UART, I2S), and RTOS task scheduling Optimize power consumption and thermal performance for always-on, battery-powered operation Build and maintain OTA update infrastructure for reliable field updates Collaborate with the on-device AI team to support model inference within memory and latency budgets Develop factory test and calibration firmware for manufacturing Debug complex hardware-software interac
