Embedded Software Architect – Edge AI MCUAustin, Texas, United StatesAmbiq is on a mission to enable intelligence everywhere — powering the AI edge revolution with the world's lowest-power semiconductor solutions.Built on our proprietary sub- and near-threshold technology, our chips deliver multi-fold improvements in energy efficiency without costly process scaling. Since 2010, we've shipped over 300 million units to customers building smarter wearables, medical devices, IoT products, and AI-powered edge applications.Our cross-functional teams span design, research, development, production, marketing, sales, and operations across Austin, Hsinchu, Shanghai, Shenzhen, and Singapore. We move fast, tackle hard problems, and create space for people to grow through complex, meaningful work that shapes the future of technology.We're looking for self-motivated, creative problem-solvers who are eager to push technological limits and make a real impact in energy efficiency.At Ambiq, we live by five values: Innovate.
Collaborate. Focus. Learn.
Achieve.If that's you, join us — the intelligence everywhere revolution starts here.Austin, TX – Onsite (5 days/week) U.S. Work Authorization Required (No Sponsorship Available)Architect the Software Foundation for Ultra-Low-Power Edge AI SiliconAmbiq 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 OwnAs Embedded Software Architect, you will:Define the software architecture for next-generation low-power Edge AI MCUsDrive early-stage functional allocation between hardware and softwareDevelop and refine Software Requirements Specifications (SRS) tied to real customer use casesLead architectural decisions across: Multi-processor communicationControl/data plane separationData movement accelerationMemory management and protectionDynamic resource allocationPower optimization strategiesDebug and visibility toolingPartner with SoC architects to influence hardware/software trade-offsSupport software prototyping to validate architectural decisionsAct as architectural SME through implementation, validation, and bring-up phasesReview designs, test plans, and implementation details to ensure alignment with architectural intentMentor engineers and define best practices across embedded teamsThis is a high-impact architectural role influencing multiple MCU generations.Technical EnvironmentYou will work deeply across:ARM Cortex-M architecturesBare metal and RTOS-based systemsAsymmetric multi-core systemsInter-processor communication (OpenAMP, RPMsg, etc.)Data movement engines and acceleration blocksMMU/MPU, caches, shared memory, dual-port memoryPower management (DVFS, clock gating, low-power states)FPGA-based emulation platforms and full reference systemsYou will be embedded within engineering teams while influencing cross-functional decisions across silicon and software domains.What We're Looking ForRequired ExperienceBS or MS in EE, CE, or CS12+ years developing embedded software for real-time systemsDeep experience on ARM Cortex-M platformsStrong C/C++ (assembly experience preferred)Experience defining and writing Software Requirements Specifications (SRS)Strong understanding of: Functional allocationRequirements traceabilityTestability across pre-silicon and post-silicon platformsExperience with asymmetric multicore architecturesStrong knowledge of memory systems, data movement, and processor interactionAbility to independently drive architectural decisionsPreferred ExperiencePower optimization strategies in embedded systemsTrustZone for M-class microcontrollersTrusted firmware environmentsGraphics, display, or audio/video processingExperience working with IP vendors and external silicon partnersWhy This Role Is DifferentDirect architectural influence on Edge AI MCU platformsClose collaboration with silicon architects and IP vendorsOwnership across early-stage definition through validationOpportunity to shape hardware/software trade-offs that impact power, performance, and scalabilityAustin-based collaboration culture with tight hardware/software integrationThis is a principal-level role for engineers who want to define system behavior — not just implement features.Location & Work AuthorizationAustin, TX – Onsite 5 days per week Must be authorized to work in the United States.
