About the Role

As a CPU Senior Architecture Engineer, you will be involved in the architectural & micro-architectural specification for a range of cutting-edge OOO superscalar CPU cores used in next-generation System-on-Chip (SoC) designs, with a strong emphasis on performance and power/area efficiency. This role will value experience working on OOO superscalar CPUs, coherency in multi-core systems, and workload performance analysis. Successful candidates will be expected to collaborate with other architecture teams, design teams and other partners.

Responsibilities

  • ● Authoring specifications for the CPU core in sufficient detail for design teams and other stakeholders. Conducting reviews as necessary.
  • ● Close collaboration with other architects to optimize CPU system performance. This will include teams working on closely coupled accelerator engines, teams responsible for defining the SOC, and SW teams.
  • ● Using simulators and other tools to model key workloads in terms of power & performance. This may involve "what if" tradeoff analysis on features and design choices.
  • ● Close collaboration with design teams on implementation & verification. This may also include power analysis and process related decision making.
  • ● Required Qualifications
  • ● + years of experience in OOO superscalar CPU designs. Demonstrated ability to evaluate micro-architecture trade-offs in terms of performance, power, and area.
  • ● Understanding of CPU micro-architectures, memory hierarchy, and coherency in multi-core systems.
  • ● Understanding of SoC design principles and the integration of accelerators, CPUs, and memory subsystems.
  • ● Additional areas of interest:
  • ● Knowledge of RISC-V architecture, hardware and software aspects.
  • ● Familiarity with AI/ML software frameworks and their mapping onto hardware.
  • ● What do we offer
