Singapore AMBIQ MICRO SINGAPORE PRIVATE LTD. Full time $150,000 - $250,000 per year

Company Overview

Ambiq's mission is to enable intelligence everywhere by delivering the lowest power semiconductor solutions. Ambiq 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 increased power requirements of artificial intelligence (AI) computing, our customers increasingly rely 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 started in 2010 addressing the needs of battery-powered devices at the edge, where power consumption challenges were most profound. As of the beginning of 2025, we've shipped more than 270 million units worldwide.

Our innovative and fast-moving teams of design, research, development, production, marketing, sales, and operations are spread across several continents, including the US (Austin and San Jose), Taiwan (Hsinchu), China (Shenzhen and Shanghai), Japan (Tokyo), 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 new technologies. We encourage and nurture an environment for growth and opportunities to work on complex, meaningful, and challenging projects that will create a lasting impact and shape the future of technology. Join us on our quest for 100 billion devices. The edge intelligence revolution starts here.
