Job Description

Company Overview

Ambiq is a fabless semiconductor company based in Austin, TX developing the world’s most energy efficient circuit and software platform for the Internet of Things.  Using technology originally invented by leading low power circuit researchers at the University of Michigan, Ambiq is developing a series of ultra-low power products on the Subthreshold Power Optimized Technology (SPOT) Platform.  The company’s Apollo line of MCUs has shattered energy efficiency records and sits at the heart of some of the most innovative wearable and IoT products in the world.  Key markets include wearables, smart home devices, smart cards, wireless sensors, medical devices, and a wide variety of other wireless devices. 

The Ambiq team includes low power experts and industry veterans and is growing quickly.  New team members will join an evolving and exciting environment that values technology-based innovation, adaptation, and, above all, a picojoule fanaticism.

Scope and Responsibilities

The SoC Security Architect will be responsible for developing security solutions for next-generation ultra-low power Ambiq SoC products.  The candidate will work with the Marketing, Advanced Development and Engineering teams to develop next generation security architecture specifications and ensure delivery into Ambiq products.  Areas of interest include: low power embedded SoCs, cryptographic accelerators/algorithms/protocols, security threat modeling/assessment, security architectures such as Platform Security Architecture (PSA)/Trustzone and Trusted Execution Environments.  The candidate will have sufficient experience with system level architecture and requirements on the overall SoC architecture, hardware/software partitioning, threat modeling, attack vector analysis, asset protection, lifecycle state management and provisioning processes. This position will report directly to the VP of Architecture. 

Specific Responsibilities

  • Work with Ambiq’s Marketing, Advanced Development, architecture, and engineering teams to drive security architecture and development for new ultra-low power SoCs on Ambiq’s technology and product roadmaps
  • Develop high level specifications and drive security objectives, threat modeling/assessment and security design reviews
  • Define security flows and requirements at system level and appropriate hardware/software partitioning to meet overall security objectives
  • Work with the engineering teams to transition architecture specification into Ambiq’s products
  • Interface with customers to understand critical security requirements and enablement of Ambiq security solutions through product lifecycle
  • Work with systems, solutions, and software teams to ensure robust interfaces and support key product use cases
  • Support post-silicon analysis, security testing and delivery of secure products to customers for mass production

Experience Required

The candidate should be comfortable with independent specification, analysis and development from high level concepts through design and validation as well as collaborative development with software and hardware engineering.  A deep knowledge of security architectures, flows, standards/protocols in embedded systems specifically targeting wearable, IoT and mobile systems is critical along with specific experience delivering security solutions to market. Candidate must have experience with defining threat models and performing threat assessments along with experience in security testing/certification. A working knowledge of general SoC architecture, multi-processor communication, cryptographic hardware and fabric interconnect (AHB, AXI, NoCs) is required. The candidate should be comfortable with full system dataflows and modeling to guide hardware and software analysis and development. Good written and oral communication is a must. Candidate must be able to effectively drive security testing engagements and security procedures across full product development supply chain.

Specific Experience

  • 8+ years of embedded security architecture in SoC products
  • Specific experience with ARM Cortex-M, RISC-V, or similar processor architecture based designs targeting wearable/IoT and mobile products strongly preferred
  • Experience developing and/or integrating security architectures from idea to specification to design to post-silicon validation
  • Experience with embedded security protocols/standards/processes is a must
  • Experience with Platform Security Architecture (PSA) and Trustzone or similar is strongly preferred
  • Trusted firmware and secure firmware update flows preferred
  • Experience with security testing houses and flows preferred

Key Personal and Professional Attributes

Ambiq management is building a company that values continued technology innovation, a fanatical attention to customer needs, collaborative decision making, and, above all, enthusiasm for energy efficiency.  The incoming candidate should embrace these same values.  The successful candidate must be self-motivated, extremely creative, and should be comfortable learning exciting new technologies.  This is an opportunity for growth and an opportunity to work on complex, interesting, and challenging projects.
