Senior Engineer, System Test

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. 

As the Senior Engineer, System Test at Ambiq, you will be part of a team responsible for development and execution of system-level tests to improve design coverage and measure system performance for ARM Cortex-M4, Cortex-M55, DSP and NPU-based platforms. You will also engage in deep-dive debugging across multiple layers, from high-level system behavior to low-level firmware and driver code and hardware blocks, to ensure optimal integration, reliability, and performance.   

 This role will work closely with global MCU software, validation, and architecture teams, collaborating closely with SoC design engineers, firmware developers, and hardware teams to define and execute comprehensive test and validation plans for MCU-based platforms.  

 The successful candidate will be a proactive, detail-oriented engineer with strong problem-solving skills, comfortable working across hardware and software boundaries. They will thrive in an environment that values technical excellence, effective cross-team collaboration, and continuous learning..  

 The person in this role will define, design and implement test cases for the SDK primarily using C, architected for automation using Ambiq's automation framework – primarily using Python, validate system functionality and performance, perform in-depth debugging of MCU subsystems including Fabrication, DMA, and peripherals, and have key contributions in defining system test methodology and automation.

• Plan, develop, and execute system-level test strategies for ARM Cortex-M4, Cortex-M55, DSP, and NPU-based platforms.
• Design and implement firmware test frameworks to validate system functionality, performance, and reliability across multiple integration layers.
• Develop, maintain, and execute embedded test cases for the SDK using primarily using C and assembly.
• Develop, maintain, and execute automation using Python or other scripting languages
• Measure, analyze, and report on system performance metrics, identifying bottlenecks and recommending optimizations.
• Debug and resolve complex issues spanning from application-level interactions to low-level firmware, drivers, and hardware interfaces.
• Collaborate with architecture, hardware, and software teams to define test requirements and acceptance criteria.
• Support pre-silicon validation on FPGA/emulation platforms as well as post-silicon bring-up, validation, and debugging.
• Contribute to continuous improvement of test methodologies, tools, and workflows.
• Mentor and guide junior engineers in system testing, embedded development, and automation best practices. 

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field. 
• 4+ years of experience in embedded system-level testing, validation, or embedded system development, preferably on ARM Cortex-M architectures.
• Proficiency in C/C++ and Assembly programming for embedded targets
• Strong understanding of MCU architecture, including DMA, memory hierarchy, peripheral interfaces, and interrupt handling.
• Knowledge of embedded RTOS concepts (FreeRTOS, Zephyr, etc.) preferred.
• Strong Python programming skills for test automation and data analysis.
• System-level debugging experience is required.
• Familiarity with hardware bring-up, schematic/block diagram reading, and interface validation is highly desirable.
• Strong debugging skills using oscilloscopes, logic analyzers, and other lab equipment.
• Familiarity with MCU peripherals such as display, audio, and wireless interfaces is a plus.
• Excellent problem-solving skills, able to work independently and manage multiple priorities.
• Good communication skills and ability to work effectively in cross-functional teams.
