Sr Staff Software Engineer Security

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 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.  

A 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.  

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

Responsibilities 

• Enable Trusted Execution Environments (TEE) support on Ambiq’s TrustZone (ARM v8) enabled Apollo and Atomiq family of products. 

• 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 Bootloader software updates laying the foundation for TEE and implementing necessary elements required for TF-m. 

• Help drive SDK infrastructure and architectural changes to support TF-m-enabled systems. 

• Spearhead Ambiq's compliance efforts by supporting industry-leading security certifications like ARM PSA and SESIP. 

• 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 Cryptocell. Expertise 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.

What We Do

Ambiq makes unprecedented energy-efficient SoCs and ultra-low power platform solutions that enable edge AI on billions of battery-powered devices. Our mission is to put intelligence everywhere by delivering the lowest-power semiconductor solutions on the planet. With SPOT® technology and the Apollo SoC family Ambiq empowers innovators to build smarter longer-lasting wearables IoT smart home healthcare and industrial devices.Ambiq has helped leading manufacturers worldwide develop products that last weeks on a single charge (rather than days) while delivering a maximum feature set in compact industrial designs. Ambiq's goal is to take Artificial Intelligence (AI) where it has never gone before in mobile and portable devices using Ambiq's advanced ultra-low power system on chip (SoC) solutions. Ambiq has shipped more than 200 million units as of March 2023. The next generation of AI will not depend on constant cloud connectivity.It will run directly on ultra-low-power silicon in wearables sensors and embedded systems.At Ambiq we design and ship production silicon that enables:Real-time inference on constrained devicesModels optimized to run in tens of KBExtreme power efficiency for battery-operated systemsDeep hardware/software co-designThis is not research. It’s deployed technology.
