Software Architect

Scope

As the Software Architect at Ambiq, you will drive the software architecture and requirements for our latest family of low-power Edge AI MCUs. As a Software Architect, you will be working closely with our SoC hardware architects, product marketing, and our IP vendors to develop solid functional allocations and requirements for our software development and system test teams.

The role will cover the areas of multi-processor communications, data movement acceleration, virtual memory management, dynamic resource allocation, power optimization, and debug tools. You will be embedded into Ambiq's software development teams as the subject matter expert for the duration of the product development.

The successful candidate will have extensive experience in the early-stage software development process. The candidate must have strong experience in embedded software programming on ARM Cortex-M processors using RTOS. They must be familiar with methods for functional allocation, requirements traceability, Software Requirement Specification content, and make vs. buy analysis for commercial and open-source software.

Responsibilities

• Requirements analysis based on disparate and preliminary information from SoC hardware architecture team, product marketing, other software architects, and software development teams resulting in contributions to a software requirements specification for the device. This should include any software prototyping required to refine the architectural understanding and requirements.
• Working closely with our field, product marketing, and system test teams to understand our Alpha customer use cases and their impact on requirements and testability.
• Engaging during the software implementation and test phases to review designs, test plans, code, and test case results as a SME for certain aspects of the SoC software architecture.
• Support performance and power optimization of the areas for which you are responsible.
• Define and enforce architectural standards, guidelines, and best practices.
• Collaborate with cross-functional teams to align architectural decisions with overall business objectives.
• Diagnose and resolve complex technical issues and recommend trade-offs between software and hardware implementations.
• Collaborate effectively with cross-functional teams to achieve project goals.
• Mentor and guide junior team members.

Qualifications

• A Bachelor's of Science or Master's in Electrical Engineering, Computer Engineering, or Computer Science.
• 12+ years of experience developing embedded software for real-time environments (bare metal and RTOS).
• Experienced in code development in C/C++ and assembly language for embedded targets using ARM Cortex-M processors.
• Experience in writing software requirements specifications with an eye towards customer use cases, derived software requirements, and testability on FPGA-based emulation platforms, as well as full system reference designs.
• Experience with asymmetric multicore systems and control/data plane interaction, including inter-processor communication via remote processor messaging frameworks (e.g., OpenAMP or RPMsg).
• Experience with general-purpose data movement engines, memory management units, memory protection, L1/L2 caches, shared memories, and dual-port memories.
• Experience in power optimization for embedded systems is desirable. Familiarity with voltage and frequency scaling, clock gating, sleep/wake cycles, and low-power modes of processors and peripherals.
• Familiarity with at least one MCU IDE on Windows from ARM/Keil, IAR, Eclipse, or others.
• Familiarity with Trust Zone for M-Class microcontrollers and/or Trusted Firmware for microcontrollers is preferred.
• Experience with Graphics, Display and Audio/Video processing in embedded systems preferred.
• The candidate must be able to independently manage assigned tasks, prioritize workload, and meet deadlines with minimal supervision. Proactive problem-solving skills and the ability to seek clarification when needed are essential.
