Since 2010, we've shipped over 300 million units to customers building smarter wearables, medical devices, IoT products, and AI-powered edge applications.\nOur 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.\nWe're looking for self-motivated, creative problem-solvers who are eager to push technological limits and make a real impact in energy efficiency.\nAt Ambiq, we live by five values: Innovate. Collaborate. Focus. Learn. Achieve.\nIf that's you, join us - the intelligence everywhere revolution starts here.\n This role will be on-site 5 days a week in NW Austin.\nAs a member of the Security team at Ambiq, the Senior Staff Software Engineer, Security will participate in developing and supportingAmbiq’s TrustZone-based Trusted Execution Environment (TEE) offering for the Apollo & Atomiq SoC and emulation platforms. \nThis role will work within our Security software development team and will work closely with SoC and system architecture teams, Security architects and local SoC design team, focusing on enabling the TrustZone functions in Ambiq’s SoC and software offerings. \nA successful candidate should be a fast-learning, result-driven, and self-motivated team player with an “always learning” mindset. He should have an inquiring spirit and be comfortable in a lab environment and with hands-on debugging of embedded systems. \nThe candidate will be involved in the extension of each of these to cover new MCU members of the family as they become available. \nResponsibilities \nEnable Trusted Execution Environments (TEE) support on Ambiq’s TrustZone (ARM v8) enabled Apollo and Atomiq family of products. \nTake reference Trusted Firmware for Microcontroller (TF-m) implementation from ARM and adapt it to suit the specifics of Ambiq’s TrustZone implementation \nDrive necessary Secure Bootloader software updates, laying the foundation for TEE and implementing necessary elements required for TF-m. \nHelp drive SDK infrastructure and architectural changes to support TF-m-enabled systems. \nSpearhead Ambiq's compliance efforts by supporting industry-leading security certifications like ARM PSA and SESIP. \nWork closely with Alpha customers to ensure seamless integration of TF-m by testing and verifying its functionality in customer builds \nWork closely with the SQA and System Test team to help define and implement test cases for security deliverables to ensure full coverage. \n Qualifications \nA Bachelor's of Science or Master's in Electrical Engineering, Computer Engineering, or Computer Science. \n10+ years of experience developing embedded software for real-time environments (bare metal and RTOS). \nAt least 5 years working on embedded security, cryptography, TrustZone, and secure boot. \nSolid understanding & proven ability to port and support ARM Trusted Firmware for Microcontrollers (TF-m). \nUnderstanding of security implications for the embedded systems, and experience with IoT security concepts (TrustZone, Root of Trust, Secure Boot, Secure Update) \nFamiliarity and prior experience with ARM Platform Security Architecture (PSA), ARM TrustZone for microcontrollers, cryptographic algorithms/protocols, and ARM Cryptocell. Expertise in embedded C and assembly language, particularly for system initialization. \nFamiliarity with at least one MCU IDE on Windows from ARM/Keil, IAR, Eclipse, or others. \nThe 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. \nExperience in prioritizing tasks and managing workflow for oneself and potentially others in the future.
