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.
About the Role
We’re looking for a Design for Test (DFT) Intern to join our SoC team and contribute to scan and MBIST implementation and verification for our ultra-low power chips. In this role, you’ll gain hands-on experience with industry standard DFT tools and methodologies, learn how to improve manufacturing test coverage and test quality, and work alongside experienced engineers designing edge AI products. This internship is an excellent opportunity to apply what you’ve learned in class, explore industry-standard tools, and see how your work connects to the technology powering everyday devices.
