Staff Engineer - Embedded Software

As the Staff Embedded Software Engineer, MCU Software at our client, 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.

• Lead the design, development, and maintenance of the HAL interfaces for memory management unit (MMU) and Data Movement Engine (DME) subsystems, as well as Caches, MPU, and other general MCU management.
• Design, develop, and maintain examples and software test cases for these blocks.
• Take a key role in the 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 6+ years of experience or BS ECE/CS with 8+ years of experience, with at least 3 years focusing on MMU, caches, DMA, or related subsystems;
• Deep understanding of ARM architectures
• Strong understanding with MMUs including virtual memory, paging, and physical address translation;
• Solid experience with DMA engines, chained and scatter/gather transfers. Hands-on experience profiling and optimizing memory access patterns, DMA throughput, and cache usage;
• Experience with memory protection, isolation, and secure DMA for trusted execution environments is a plus.
• Deep understanding of embedded RTOS required,
• Experience with developing embedded MCU code in C and assembly language on Arm Cortex-M Processors;
• 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.

• M-profile preferred;
• Experience working with multicore embedded processing systems is preferred;
• Zephyr and FreeRTOS preferred;
