Principal Embedded Software Architect – Edge AI MCU
About The Position
Ambiq designs and ships ultra-low-power Edge AI MCUs that enable real-time intelligence directly on device. We are expanding our Austin engineering organization and hiring a Principal Embedded Software Architect to define the software architecture and requirements for our next-generation Edge AI MCU platforms. This role sits at the hardware/software boundary — partnering directly with SoC architects, product teams, IP vendors, and embedded software leaders to shape how our silicon is exposed, controlled, optimized, and validated. You won’t just write code. You will define how the system behaves. This is a high-impact architectural role influencing multiple MCU generations.
Requirements
- BS or MS in EE, CE, or CS
- 12+ years developing embedded software for real-time systems
- Deep experience on ARM Cortex-M platforms
- Strong C/C++ (assembly experience preferred)
- Experience defining and writing Software Requirements Specifications (SRS)
- Strong understanding of: Functional allocation
- Requirements traceability
- Testability across pre-silicon and post-silicon platforms
- Experience with asymmetric multicore architectures
- Strong knowledge of memory systems, data movement, and processor interaction
- Ability to independently drive architectural decisions
Nice To Haves
- Power optimization strategies in embedded systems
- TrustZone for M-class microcontrollers
- Trusted firmware environments
- Graphics, display, or audio/video processing
- Experience working with IP vendors and external silicon partners
Responsibilities
- Define the software architecture for next-generation low-power Edge AI MCUs
- Drive early-stage functional allocation between hardware and software
- Develop and refine Software Requirements Specifications (SRS) tied to real customer use cases
- Lead architectural decisions across: Multi-processor communication
- Control/data plane separation
- Data movement acceleration
- Memory management and protection
- Dynamic resource allocation
- Power optimization strategies
- Debug and visibility tooling
- Partner with SoC architects to influence hardware/software trade-offs
- Support software prototyping to validate architectural decisions
- Act as architectural SME through implementation, validation, and bring-up phases
- Review designs, test plans, and implementation details to ensure alignment with architectural intent
- Mentor engineers and define best practices across embedded teams
