Hark is an AI company building advanced personal intelligence through bespoke hardware devices and agentic systems that see, hear, remember, and act on your behalf.
<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>As the RF antenna engineer, you will be responsible for the end-to-end wireless design for our first-generation consumer wearable/device. You aren't just placing components; you are architecting a complex ecosystem of Cellular, Wi-Fi, BT, GNSS, NFC, and UWB radios within an extremely tight physical envelope. Your mission is to deliver optimal wireless functionality for the users.</p> <p><strong>Responsibilities</strong></p> <ul> <li>Architect the multi-radio systems, ensuring coexistence and optimal performance across a wide spectrum (sub-GHz to 8GHz+).</li> <li>Design and simulate custom, miniaturized antennas (LDS, FPC, or metal frame) that thrive in high-density environments.</li> <li>Partner with Industrial Design (ID) and Mechanical Engineering (ME) to find the "sweet spot" between aesthetic beauty and RF transparency.</li> <li>Develop RF strategies that prioritize ultra-low power consumption for battery-constrained performance.</li> <li>Own the product through EVT, DVT, and PVT phases, managing factory calibration, OTA testing, and global regulatory certifications (FCC/CE/PTCRB/GCF).</li> <li>Lead engagements with chipset vendors and antenna fabricators to push the limits of what is commercially possible.</li> </ul> <p><strong>Requirements</strong></p> <ul> <li>10+ years in RF/Antenna design, with at least 2 full lifecycles leading a high-volume consumer electronic product to mass market.</li> <li>Expert-level proficiency in ANSYS HFSS, CST Studio Suite, or similar EM simulation tools.</li> <li>Full-stack understanding of RF front-end (RFFE) design, including filters, switches, LNAs, and matching networks.</li> <li>Proven experience with 5G/4G LTE, Wi-Fi 6E/7, Bluetooth 5.x, GNSS (L1/L5), and UWB.</li> <li>Strong hands-on skills with VNA, Spectrum Analyzers, and Anechoic Chamber testing (TRP/TIS).</li> </ul> <p><strong>Bonus Qualifications</strong></p> <ul> <li>Experience with Human Body Interaction (SAR) and how it affects antenna tuning in wearables.</li> <li>A background in UWB (Ultra-Wideband) for precision ranging and spatial awareness.</li> </ul> <p><strong><span data-sheets-root="1">Compensation</span></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.
