Company Overview

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.

Scope

As the Staff Engineer - Embedded MCU Software at Ambiq, you will drive the development and testing of core MCU functions in AmbiqSuite SDK on Ambiq SoC devices and emulation platforms. These include features like memory management (Cache, MMU, MPU), data movement (DMA), and general MCU management. You will also be contributing to defining and implementing the multicore software framework and related infrastructure.

This role will work within our global MCU software development team and will work closely with the architecture team and the local MCU SoC design team, focusing on MCU software development and test activities.

A successful candidate should be a fast-learning, result-driven, and self-motivated team player with an “always learning” mindset. He should possess an inquiring spirit and be comfortable working in a lab environment, with the ability to execute hands-on debugging for embedded systems.

The person in this role will be responsible for extending the hardware adaptation layer (HAL) and device drivers of the SDK to new platforms as well as enhancing its features and content, with a focus on memory management and data movement subsystems. The candidate will be involved in the extension of the SDK to cover new MCU members of the family as they become available.

Responsibilities

• Design, develop, and maintain the HAL interfaces for MCU clocking, power management, MCU control, and other general MCU management subsystems.
• Responsible for developing and maintaining the trusted firmware HAL and porting layers to enable secure and scalable embedded platforms.
• Design, develop, and maintain examples and software test cases for these blocks.
• Take a key role in pre-silicon verification on FPGA, as well as post-silicon bring up, verification, performance optimization, and debug, focusing on these blocks.
• Design, develop, and maintain real-time OS ports for Ambiq MCUs.
• Support design verification (DV) and validation engineers, field engineers, and key customers as needed.

• MS in ECE or Computer Science and 3+ years of experience or BS ECE/CS with 5+ years of experience, with at least 2 years focusing on MCU management subsystems;
• Deep understanding of ARM architectures, M-profile preferred;
• Experience with MCU clocking, power management, MCU control, and other general MCU management subsystems.
• Experience with Trusted Firmware-M (TF-M), Platform Security Architecture (PSA) and CyptoCell is an added advantage.
• Experience developing in embedded C and assembly language with a focus on system initialization and low-level code;
• Deep understanding of embedded RTOS required, Zephyr and FreeRTOS preferred;
• Experience with at least one MCU IDE from ARM, Keil, IAR, Eclipse, Ozone, or other;
• Good hands-on experience on lab equipment such as oscilloscopes, logic analyzers, etc. for debugging issues;
• Experience with Jira, Confluence, and collaboration tools;
• Experience with source code control systems (git) required;
• Understanding of software testing and test automation principles;
• Excellent problem-solving skills dealing with complex system-level issues related to HW/SW debug;
• Experience with scripting languages required, and Python experience is specifically desirable;
• Strong communication and documentation skills.
