Director of Physical Design

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. 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 Define and execute the physical design strategy for low‑power MCU product lines. Build, mentor, and lead a high‑performing global physical design team.

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 Cross-Functional Collaboration Partner with architecture and RTL teams to influence early design decisions. Work closely with analog/mixed‑signal teams to integrate mixed‑signal IP into SoCs. Collaborate with product engineering and operations to ensure manufacturability and yield. Interface with foundries to align on technology capabilities, PDK updates, and design rules. Execution & Delivery Own physical design schedules, resource planning, and risk management. Ensure first‑silicon success through rigorous signoff and validation processes. Drive tape‑out readiness and post‑silicon debug support. Qualifications Required Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field. 15+ years of experience in physical design for complex SoCs, with at least 5 years in leadership roles. Proven track record of delivering multiple chips to production. Deep expertise in: Strong understanding of MCU architectures and embedded system constraints. Excellent communication, leadership, and cross‑functional collaboration skills. Preferred Experience with mixed‑signal SoCs and integration of analog IP.

A "recently separated veteran" means any veteran during the three‑year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service. An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense. An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985. Voluntary Self-Identification of Disability Form CC-305 Page 1 of 1 OMB Control Number 1250-0005 Expires 07/31/2029 Why are you being asked to complete this form?
