Sr. Staff Engineer, Timing Methodology & Signoff

Austin, Texas, United States

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.

If that's you, join us — the intelligence everywhere revolution starts here.

 

Build the silicon that powers the future of ultra-low-power computing

At Ambiq, we’re redefining what’s possible at the edge—powering next-generation AI, wearables, and IoT devices with breakthrough ultra-low-power technology. We’re looking for a Sr. Staff Engineer – Timing Methodology to take a true ownership role in driving timing from architecture to silicon—and ensuring our designs don’t just work, but excel in real-world conditions.

Why this role stands out

This isn’t a “maintain the flow” role. You’ll:

  • Own end-to-end timing convergence (block → SoC → post-silicon)
  • Shape methodology, flows, and signoff strategy
  • Work on cutting-edge FinFET, multi-patterning nodes, and unique ultra-low-power challenges
  • Directly influence PPA and product success

If you thrive on solving complex timing problems others shy away from—this is your playground.

What You’ll Do

  • Own timing convergence end-to-end, from methodology definition to SoC signoff
  • Develop and refine timing flows, constraints, and analysis methodologies
  • Drive block-level closure and SoC-level timing correlation
  • Lead signoff activities, including:
    • PVTR corner definition
    • Timing margining & ECO strategy
    • Extraction and analysis
    • Glitch/noise analysis & power/timing tradeoffs
  • Partner cross-functionally with RTL, DFT, physical design, and IP teams
  • Define and manage timing constraints across diverse IP (std cell, memory, hard IP)
  • Ensure strong pre-silicon to post-silicon correlation through close collaboration with bring-up and validation teams
  • Continuously enhance automation, scripts, and methodologies to improve efficiency and scalability
  • Stay at the forefront of STA advancements and emerging process technologies

What You Bring

  • 8+ years of experience in timing analysis and convergence
  • Deep expertise in static timing analysis (STA) using Synopsys Primetime or Cadence Tempus
  • Strong experience with block-level and SoC-level timing closure in advanced nodes
  • Solid understanding of digital design fundamentals and timing principles
  • Hands-on experience with industry-standard EDA tools (Synopsys, Cadence)
  • Proficiency in TCL, Python, or similar scripting languages
  • Strong problem-solving skills and ability to drive complex issues to closure
  • Excellent communication and collaboration skills across engineering teams

Nice to have:

  • Experience with PnR tools (Fusion Compiler, Innovus)

What Success Looks Like

  • Clean, predictable timing convergence across increasingly complex SoCs
  • Strong correlation between signoff and silicon behavior
  • Scalable methodologies that improve team velocity and design quality
  • Measurable impact on power, performance, and area (PPA)

Work Authorization

Must be currently authorized to work in the United States. We are unable to sponsor or transfer visas for this role now or in the future.

Why Ambiq

We’re small enough that your impact is immediate—and big enough to be solving problems that rival the industry’s most complex SoCs. Our ultra-low-power innovation creates entirely new timing challenges, making this an opportunity to do some of the most interesting work of your career.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

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 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
