Sr Software Engineer, Security Austin, Texas

Ambiq's mission is to enable intelligence everywhere by delivering the lowest power semiconductor solutions. Ambiq is a pioneer and 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 AI computing, our customers rely on our solutions to deliver AI to edge environments, fundamentally improving power consumption over traditional semiconductor designs without expensive process geometry scaling.

Our innovative, 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, deep commitment to customer success, collaborative problem‑solving, and an enthusiastic pursuit of energy efficiency.

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 Trust Zone‑based Trusted Execution Environment (TEE) offering for the Apollo & Atomiq SoC and emulation platforms. The role works within our Security software development team and closely collaborates with SoC and system architecture teams, Security architects, and the local SoC design team to enable Trust Zone functions in Ambiq’s SoC and software offerings.

A successful candidate is a fast learner, results‑driven, and self‑motivated team player with an "always learning" mindset, an inquiring spirit, and comfort in a lab environment 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.

• Enable Trusted Execution Environments (TEE) support on Ambiq’s Trust Zone‑enabled Apollo and Atomiq family of products.
• Take reference Trusted Firmware for Microcontroller (TF‑m) implementation from ARM and adapt it to suit Ambiq’s Trust Zone implementation.
• Drive necessary Secure
  
  BootROM software updates, laying the foundation for TEE and implementing necessary elements required for TF‑m.
• Help drive SDK infrastructure and architectural changes to support Trust Zone‑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.
• Collaborate with the SQA and System Test team to define and implement test cases for security deliverables, ensuring full coverage.

• 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, Trust Zone, and secure boot.
• Solid understanding and proven ability to port and support ARM Trusted Firmware for Microcontrollers (TF‑m).
• Understanding of security implications for embedded systems and experience with IoT security concepts (Trust Zone, Root of Trust, Secure Boot, Secure Update).
• Familiarity and prior experience with ARM Platform Security Architecture (PSA), ARM Trust Zone 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 (ARM/Keil, IAR, Eclipse, or others).
• Demonstrated ability to independently manage assigned tasks, prioritize workload, and meet deadlines with minimal supervision.
• Experience prioritizing tasks and managing workflow for oneself and potentially others, delegating effectively to keep projects on track.
