<h3><strong>Company Overview</strong>&nbsp;</h3>

<p>Ambiq's&nbsp;mission is to enable intelligence everywhere by delivering the lowest power semiconductor solutions.&nbsp;Ambiq&nbsp;is a pioneer and a leading provider of ultra-low-power semiconductor solutions based on our proprietary and patented sub- and near-threshold technologies. With&nbsp;the increasing&nbsp;power requirements of artificial intelligence (AI) computing, our customers&nbsp;are relying&nbsp;on our solutions to deliver AI to edge environments. Our hardware and software innovations fundamentally deliver a multi-fold improvement in power consumption over traditional semiconductor designs without expensive process geometry scaling. We&nbsp;began in 2010 by addressing the power consumption challenges of battery-powered devices at the edge, where they&nbsp;were most&nbsp;pronounced. As of the beginning of 2025,&nbsp;we've&nbsp;shipped more than&nbsp;280+&nbsp;million units worldwide.&nbsp;</p>

<p>Our innovative and fast-moving teams of design, research, development, production, marketing, sales, and operations are spread across several continents, including the US (Austin), Taiwan (Hsinchu), China (Shanghai and&nbsp;Shenzhen), and Singapore. We value relentless technology innovation, a deep commitment to customer success, collaborative problem-solving, and an enthusiastic pursuit of energy efficiency. We embrace candidates who also share these same values. The successful candidate must be self-motivated, creative, and comfortable learning and driving exciting&nbsp;new technologies. We encourage and nurture an environment&nbsp;that fosters growth and opportunities to work on complex, meaningful, and challenging projects, creating a lasting&nbsp;impact&nbsp;and shaping&nbsp;the future of technology. Join us on our quest for&nbsp;enabling&nbsp;billions of intelligent&nbsp;devices.
