Hardware Test 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 a Hardware Test Engineer to build the test infrastructure that ensures our AI-powered devices meet quality, reliability, and performance standards at every stage of development. You will own test strategy from board bring-up through mass production, designing fixtures, writing automation scripts, and defining the criteria that decide whether a product ships. From functional test on the bench to burn-in and stress testing at the factory, you will be the last line of defense before our devices reach users.</p> <p><strong>Responsibilities</strong></p> <ul> <li>Test Strategy: Define and own the end-to-end test plan across EVT, DVT, PVT, and production milestones.</li> <li>Fixture Design: Design and develop custom test fixtures (bed-of-nails, pogo pin, cable harness) for PCBA and system-level testing.</li> <li>Test Automation: Write automated test scripts in Python to control instruments, collect data, and generate pass/fail reports.</li> <li>Board Bring-Up: Lead electrical bring-up of new PCBAs, debugging power rails, clocks, interfaces, and peripheral functionality.</li> <li>Reliability Testing: Plan and execute environmental stress tests including thermal cycling, vibration, drop, and accelerated life testing.</li> <li>Production Support: Work with contract manufacturers to deploy and maintain test stations on the factory floor, ensuring yield and throughput targets.</li> <li>Failure Analysis: Perform root cause analysis on field returns and test failures using oscilloscopes, logic analyzers, and X-ray inspection.</li> </ul> <p><strong>Requirements</strong></p> <ul> <li>Education: BS/MS in Electrical Engineering, Computer Engineering, or a related discipline.</li> <li>Test Automation: Strong Python scripting skills for instrument control (SCPI/VISA), data analysis, and test reporting.</li> <li>Lab Instrumentation: Expert-level proficiency with oscilloscopes, multimeters, power supplies, spectrum analyzers, and logic analyzers.</li> <li>PCB Debugging: Demonstrated ability to bring up and debug complex multi-rail, mixed-signal PCBAs.</li> <li>Manufacturing: Experience deploying test systems at contract manufacturers and supporting production ramp.</li> </ul> <p><strong>Bonus Qualifications</strong></p> <ul> <li>Experience with boundary scan (JTAG), in-circuit test (ICT), and flying probe test methodologies.</li> <li>Background in RF test for Wi-Fi, Bluetooth, or cellular radios.</li> <li>Familiarity with LabVIEW, TestStand, or similar test executive frameworks.</li> <li>Experience testing products with cameras, displays, microphones, or other sensor arrays.</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.
