The security architect will engage with customers and partners to help determine the future of platform security on RISC-V and will engage with the RISC-V International Association to help drive the state of the art of computer security forward.

What you will do:

1. Define Security features
   • The security architect will be responsible for defining the platform security requirements and defining the architecture of the needed security features.
   • The security architect will be responsible for writing detailed specifications in accordance with the various functional leads (architects, SW, design and verification leads).
   • The security architect will be heavily involved in the micro-architecture to define and review the implementation of the required features.
   • The security architect will examine the core microarchitecture to assess the security and define countermeasures when vulnerabilities are identified.
   • The security architect will have the opportunity to work with a team of micro-architects, SoC architects, and performance architects in developing the microarchitecture of the security features.
2. Interface with customers
   • The security architect will have a chance to interact directly with customers to understand their needs, use cases and to help resolve their concerns/issues.
3. Interface with RVIA
   • The security architect will participate in various TG/HC related to security.

What You Should Know:

• Familiar with advanced CPU architectures and pipelines
• Has experience in SoC design flow, including spec definition, microarchitecture design, and performance modeling.
• Familiar with the common security threat models
• Familiar with the micro-architectural side-channel attacks and how they can be mitigated
• Familiarity with secure enclave solutions for high-end CPUs
• Familiarity with automotive security considerations and solutions
• Familiarity with mobile device security considerations and solutions
• Familiarity with ROP and JOP exploitation techniques
• Familiarity with security certification processes and methodologies, such as Common Criteria, PSA, SESIP, FIPS 140-3
• Familiarity with common cryptographic algorithms and systems
• Basic understanding of public key cryptography
