Sr Staff Software Engineer, Security

Company Overview 

Ambiq's mission is to enable intelligence everywhere by delivering the lowest power semiconductor solutions. Ambiq is a pioneer and a leading provider of ultra-low-power semiconductor solutions based on our proprietary and patented sub- and near-threshold technologies. With the increasing power requirements of artificial intelligence (AI) computing, our customers are relying on our solutions to deliver AI to edge environments. Our hardware and software innovations fundamentally deliver a multi-fold improvement in power consumption over traditional semiconductor designs without expensive process geometry scaling. We began in 2010 by addressing the power consumption challenges of battery-powered devices at the edge, where they were most pronounced. As of the beginning of 2025, we've shipped more than 280  million units worldwide. 

Our innovative and fast-moving teams of design, research, development, production, marketing, sales, and operations are spread across several continents, including the US (Austin), Taiwan (Hsinchu), China (Shanghai and Shenzhen), and Singapore. We value relentless technology innovation, a deep commitment to customer success, collaborative problem-solving, and an enthusiastic pursuit of energy efficiency. We embrace candidates who also share these same values. The successful candidate must be self-motivated, creative, and comfortable learning and driving exciting new technologies. We encourage and nurture an environment that fosters growth and opportunities to work on complex, meaningful, and challenging projects, creating a lasting impact and shaping the future of technology. Join us on our quest for enabling billions of intelligent devices. The intelligence everywhere revolution starts here. 

This role will be on-site 5 days a week in NW Austin.

As a member of the Security team at Ambiq, the Senior Staff Software Engineer, Security will participate in developing and supporting Ambiq’s Trustzone-based Trusted Execution Environment (TEE) offering for the Apollo & Atomiq SoC and emulation platforms.  

This role will work within our Security software development team and will closely collaborate with SoC and system architecture teams, Security architects, and the local SoC design team, focusing on enabling Trustzone functions in Ambiq’s SoC and software offerings.  

 A successful candidate should be a fast learner, results-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.  

The candidate will be involved in extending each of these to cover new MCU family members as they become available. 

Responsibilities

• Take reference Trusted Firmware for Microcontroller (TF-m) implementation from ARM and adapt it to suit the specifics of Ambiq’s Trustzone implementation 

• Drive necessary Secure BootROM software updates, laying the foundation for TEE and implement necessary elements required for TF-m. 

• Help drive SDK infrastructure and architectural changes to support Trustzone enabled systems. 

• Spearhead Ambiq's compliance efforts by supporting industry-leading security certifications like ARM Platform Security Architecture (PSA). 

• Work closely with Alpha customers to ensure seamless integration of TF-m by testing and verifying its functionality in customer builds 

• Work closely with the SQA and System Test team to help define and implement test cases for security deliverables to ensure full coverage.  

Qualifications 

• A Bachelor's of Science or Master's in Electrical Engineering, Computer Engineering, or Computer Science. 

• 10 years of experience developing embedded software for real-time environments (bare metal and RTOS). 

• At least 5 years working on embedded security, cryptography, trustzone and secure boot. 

• Solid understanding & Proven ability to port and support ARM Trusted Firmware for Microcontrollers (TF-M). 

• Understanding of security implications for the embedded systems, and experience with IoT security concepts (TrustZone, Root of Trust, Secure Boot, Secure Update) 

• Familiarity and prior experience with ARM Platform Security Architecture (PSA), ARM Trustzone for microcontrollers, cryptographic algorithms/protocols, and ARM CryptocellExpertise in embedded C and assembly language, particularly for system initialization. 

• Familiarity with at least one MCU IDE on Windows from ARM/Keil, IAR, Eclipse, or others. 

• 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. 

• Experience in prioritizing tasks and managing workflow for oneself and potentially others in the future. Ability to delegate effectively and keep projects on track to achieve desired outcomes.
