Ambiq Micro, Inc. • Austin, TX

4h • Onsite

About The Position

Ambiq's mission is to enable intelligence everywhere by delivering the lowest power semiconductor solutions. Ambiq is a pioneer and a leading provider of ultra-low-power semiconductor solutions based on our proprietary and patented sub- and near-threshold technologies. With the increasing power requirements of artificial intelligence (AI) computing, our customers are relying on our solutions to deliver AI to edge environments. Our hardware and software innovations fundamentally deliver a multi-fold improvement in power consumption over traditional semiconductor designs without expensive process geometry scaling. We began in 2010 by addressing the power consumption challenges of battery-powered devices at the edge, where they were most pronounced. As of the beginning of 2025, we've shipped more than 280+ million units worldwide.
Our innovative and fast-moving teams of design, research, development, production, marketing, sales, and operations are spread across several continents, including the US (Austin), Taiwan (Hsinchu), China (Shanghai and Shenzhen), and Singapore. We value relentless technology innovation, a deep commitment to customer success, collaborative problem-solving, and an enthusiastic pursuit of energy efficiency. We embrace candidates who also share these same values. The successful candidate must be self-motivated, creative, and comfortable learning and driving exciting new technologies. We encourage and nurture an environment that fosters growth and opportunities to work on complex, meaningful, and challenging projects, creating a lasting impact and shaping the future of technology. Join us on our quest for enabling billions of intelligent devices. The intelligence everywhere revolution starts here.
This role will be on-site 5 days a week in NW Austin.
Scope
Join our MCU Software Security team and help us build and test the software that protects the very first steps a chip takes when it powers on. You’ll work on the Secure Boot ROM (SBR) and Secure Boot Loader (SBL) — critical pieces of code that ensure only trusted, authenticated software can run on our devices. This is your chance to learn how real-world embedded systems stay secure, from the very first instruction executed.

Requirements

• Currently pursuing a degree in Computer Science or Electrical Engineering, with a strong software bent.
• Familiarity and experience with C programming and Python Scripting (Arm assembly knowledge is a plus).
• Interest in computer security, embedded systems, or chip design.
• Strong problem-solving skills and curiosity about how hardware and software come together.
• Eagerness to learn and work as part of a collaborative team.

Responsibilities

• Help develop and test the Secure Bootrom and Bootloader (mostly written in C, with some assembly and Python).
• Work with pre-silicon FPGA prototypes that mimic real chips to verify functionality before silicon fabrication.
• Write test plans and create test cases to verify security features, such as authentication and encryption.
• Contribute to automated test suites that run on both FPGA platforms and first-silicon devices.
• Get exposure to SDK tools, hardware abstraction layers (HAL), and documentation that our customers use.
