Senior Embedded Software Engineer

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. Scope As a Senior Embedded Software Engineer at Ambiq, you will lead the development, integration, and verification of the AmbiqSuite SDK for common IP blocks across Ambiq’s advanced SoC and emulation platforms. In this role, you will collaborate closely with cross-functional experts throughout the IC development lifecycle, including SoC Architecture, IC Design, Production, Applications, and Customer Enablement teams. Your work will play a key role in enabling customers to successfully develop and deploy products on Ambiq’s latest SoC platforms. The successful candidate should be a fast learner, results-driven, self-motivated, and collaborative team player with an “always learning” mindset. You should bring strong hands-on experience in low-level embedded C programming and be comfortable working in a lab environment, performing hardware bring-up, debugging, and validation. This role is responsible for extending the hardware abstraction layer (HAL) and device drivers within the SDK to support new platforms, while continuously improving SDK features, quality, and content. You will also contribute to expanding SDK support for new MCU family members as they are introduced. Responsibilities Lead the design, development, and maintenance of HAL interfaces for MCU common blocks, including data movement engines, clock management, power management, and MCU control. Design, develop, and maintain software examples and test cases for MCU common blocks. Play a key role in pre-silicon verification on FPGA platforms and in post-silicon bring-up, verification, and debug, focusing on MCU cores and common blocks. Develop and maintain real-time operating system ports for Ambiq MCUs. Collaborate with and support design verification (DV) and validation engineers, field engineers, and key customers as needed. Qualifications The Senior Embedded Software Engineer should have strong experience in the design, development, and use of HAL and BSP libraries for MCU-based products. Experience with embedded applications for wearable devices is preferred. The ideal candidate will also have extensive hands-on experience developing for and debugging on Arm-based platforms. MS in Electrical and Computer Engineering or Computer Science, or other related field with 3-5 years of relevant experience, or Bachelor’s degree in the same fields with 4-6 years of relevant experience. Deep understanding of Arm Cortex-M architectures. Proven experience developing embedded MCU software in C and assembly for Arm Cortex-M processors. Strong understanding of embedded RTOS concepts and development; FreeRTOS experience preferred. Experience with at least one MCU IDE for ARM, such as Keil, IAR, Eclipse, Ozone, or equivalent. Solid understanding of common MCU peripherals and interfaces, such as SPI, I2C, UART, etc. Hands-on experience using lab equipment such as oscilloscopes and logic analyzers for system bring-up and debugging. Experience with Jira, Confluence, and other collaboration tools. Proficiency with source code version control systems, including Git. Good understanding of software testing and test automation principles. Strong problem-solving skills, with the ability to debug complex system-level hardware and software issues. Experience with scripting languages is required; Python experience is highly desirable. Strong written and verbal communication skills, along with solid technical docume…
