Architect the Software Foundation for Ultra-Low-Power Edge AI Silicon

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.

What You’ll Own

As Principal Architect, you will:

  • 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.

Technical Environment

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.

What We’re Looking For

Required Experience

• BS or MS in EE, CE, or CS

• 12+ years developing embedded software for real-time systems

Why This Role Is Different

• 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.
