Electrical 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 are looking for an electrical engineer to own the end-to-end power architecture of our next-generation portable devices. You will be responsible for ensuring our products are safe, efficient, and long-lasting. From selecting the right battery chemistry to fine-tuning PMIC registers and creating complex<strong> </strong>power models, you will ensure every milliwatt is accounted for.</p> <p><strong>Responsibilities</strong></p> <ul> <li>Power Architecture: Define the power distribution network (PDN) and select key components, including PMICs, chargers, fuel gauges, and protection ICs.</li> <li>Battery Management: Lead the selection, characterization, and safety validation of Li-ion/Li-poly battery cells.</li> <li>Power Modeling &amp; Simulation: Develop detailed power models to predict battery life across various user scenarios (idle, peak load, standby).</li> <li>Charging Systems: Design and optimize wired (USB-C PD) and/or wireless charging circuits, ensuring thermal stability and fast-charging compliance.</li> <li>Efficiency Analysis: Conduct bench-level efficiency measurements for DC-DC converters (Buck, Boost, LDO) and optimize firmware settings for peak performance.</li> <li>Peak Power Management: Develop power model and management strategy to overcome system brownout.&nbsp;</li> <li>Regulatory Compliance: Ensure power designs meet global safety standards (UL, IEC, UN38.3) and EMI/EMC requirements</li> </ul> <p><strong>Requirements</strong></p> <ul> <li>Education: BS/MS in Electrical Engineering.</li> <li>PMIC Expertise: Hands-on experience integrating and configuring high-performance PMICs (e.g., Qualcomm, TI, Nordic, or Maxim).</li> <li>Battery Tech: Deep understanding of Battery Management Systems (BMS), including fuel gauging algorithms and state-of-charge (SoC) estimation.</li> <li>Precision Measurement: Expert-level skills using power analyzers, electronic loads, and high-resolution current sense tools.</li> <li>PDN Integrity: Strong understanding of PCB layout for power, focusing on minimizing losses and managing high-current paths.</li> </ul> <p><strong>Bonus Qualifications</strong></p> <ul> <li>Software Familiarity: Experience working with software team on driver-level power management or I2C/SMBus communication.</li> <li>Thermal Modeling: Experience using tools like Flotherm or Icepak to simulate the thermal impact of power dissipation.</li> <li>Simulation: Proficiency in SPICE or MATLAB for transient analysis and loop stability modeling.</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. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.</p> <p>&nbsp;</p>
