Company Overview

Ambiq is on a mission to enable intelligence everywhere — powering the AI edge revolution with the world’s lowest‑power semiconductor solutions.

Built on our proprietary sub‑ and near‑threshold technology, our chips deliver multi‑fold improvements in energy efficiency without costly process scaling. Since 2010, we’ve shipped over 300 million units to customers building smarter wearables, medical devices, IoT products, and AI‑powered edge applications.

Our cross‑functional teams span design, research, development, production, marketing, sales, and operations across Austin, Hsinchu, Shanghai, Shenzhen, and Singapore. We move fast, tackle hard problems, and create space for people to grow through complex, meaningful work that shapes the future of technology.

We’re looking for self‑motivated, creative problem‑solvers who are eager to push technological limits and make a real impact in energy efficiency.

At Ambiq we live by five values:Innovate. Collaborate. Focus. Learn. Achieve.

Scope

We are seeking experienced Memory Design Engineer to work on the architecture, design, compiler development, characterization, and silicon validation of embedded SRAM and Register File (RF) IPs for ultra‑low‑power SoCs. The ideal candidate will possess strong expertise in SRAM compiler development, custom memory circuit design, timing and power characterization, silicon correlation, and production‑quality memory IP delivery. This role requires close collaboration with architecture, physical design, product engineering, foundry, EDA vendors, and silicon validation teams to develop highly optimized embedded memories operating across conventional, near‑threshold, and sub‑threshold voltage ranges. This role is critical in ensuring robust memory operation across extreme low‑voltage conditions, aligned with Ambiq SPOT principles.
