Principal Embedded Software Architect – Edge AI MCU

Austin TX – Onsite (5 days/week)
U.S. Work Authorization Required (No Sponsorship Available)

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.

As Principal Architect you will:

• 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

This is a high-impact architectural role influencing multiple MCU generations.

You will work deeply across:

• ARM Cortex-M architectures

• Bare metal and RTOS-based systems

• Asymmetric multi-core systems

• Inter-processor communication (OpenAMP RPMsg etc.)

• Data movement engines and acceleration blocks

• MMU/MPU caches shared memory dual-port memory

• Power management (DVFS clock gating low-power states)

• FPGA-based emulation platforms and full reference systems

You will be embedded within engineering teams while influencing cross-functional decisions across silicon and software domains.

• 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

• 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

• Direct architectural influence on Edge AI MCU platforms

• Close collaboration with silicon architects and IP vendors

• Ownership across early-stage definition through validation

• Opportunity to shape hardware/software trade-offs that impact power performance and scalability

• Austin-based collaboration culture with tight hardware/software integration

This is a principal-level role for engineers who want to define system behavior — not just implement features.
