Director of Physical Design

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 290 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. If that's you, join us — the intelligence everywhere revolution starts here.   This role will be on-site 5 days a week in NW Austin. Scope   We’re seeking an accomplished Director of Physical Design to lead and scale our physical implementation organization for next-generation ultra-low-power microcontroller (MCU) products. This is a strategic, high-impact leadership role responsible for driving the physical design roadmap, ensuring world-class PPA (power, performance, area), and delivering robust silicon for high-volume embedded applications. You will guide a multidisciplinary team across physical implementation, methodology, and signoff, partnering closely with architecture, RTL design, analog/mixed‑signal, verification, and product engineering to bring innovative MCU solutions to market. Key Responsibilities Leadership & Strategy Define and execute the physical design strategy for low‑power MCU product lines. Build, mentor, and lead a high‑performing global physical design team. Establish best‑in‑class methodologies for low‑power, high‑reliability physical implementation. Drive continuous improvement in design flows, automation, and signoff quality. Physical Implementation Oversee full‑chip and block‑level physical design including: Floorplanning Power planning and low‑power architecture implementation Clock tree synthesis (CTS) Place & route (P&R) Timing closure Physical verification (DRC/LVS) EM/IR and rel-ability signoff Ensure optimal PPA tradeoffs tailored for ultra‑low‑power MCU architectures.
