About the Role

We are seeking a Silicon Design Lead to architect, microarchitect, and implement key IP and subsystems for our AI hardware platforms. This role involves translating functional, performance, and security requirements into efficient silicon designs, managing technical decisions from architectural definition through implementation and integration. A significant focus will be on hardware security implementation in close partnership with the Security team, translating their requirements into silicon microarchitecture while balancing security with performance, power, area, and complexity. The other focus is on driving general silicon architecture and microarchitecture.

Responsibilities

  • Own architecture, microarchitecture, and implementation of silicon IP and subsystems, from requirements and design specifications through integration and validation.
  • Define hardware interfaces, data flows, and microarchitectural tradeoffs to meet functional, performance, power, and area requirements.
  • Partner closely with OpenAI’s Security team to translate security architecture, requirements, and threat models into implementable hardware capabilities.
  • Design and integrate hardware security mechanisms, including encryption, key management, access controls, isolation, and data protection across silicon subsystems.
  • Evaluate architectural and implementation tradeoffs to ensure security capabilities meet functional and performance requirements.
  • Collaborate with silicon architects, RTL, verification, firmware, and software teams to drive subsystem design, integration, and validation.
  • Review and contribute to RTL implementations, ensuring designs align with architectural intent and system requirements.
  • Evaluate existing and third-party IP, identify architectural or implementation gaps, and drive solutions across subsystem boundaries.

Requirements

  • Strong experience in silicon IP or subsystem-level architecture, microarchitecture, and implementation.
  • Owned hardware IP or subsystem designs from architectural definition through implementation and integration.
  • Experience implementing hardware security features such as memory encryption, key management, access controls, isolation, or secure boot.
  • Understand how to translate functional and security requirements into hardware architectures, interfaces, and microarchitectural specifications.
  • Working knowledge of RTL design and coding proficiency in Verilog or SystemVerilog, with the ability to read, review, and contribute to RTL.
  • Ability to evaluate performance, power, area, and complexity tradeoffs across silicon designs.
  • Effectively work across security, silicon architecture, RTL, verification, firmware, and software teams to drive designs from concept through execution.
  • Broader SoC-level architecture or integration experience is ideal, though deep IP or subsystem-level expertise is sufficient.
  • Candidates may need to meet certain legal status requirements to comply with U.S. export control laws and regulations.
