Job description

The Role

As a CPU Architecture Staff Engineer, you will be leading 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 is a leadership role that demands technical expertise of the workings of 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.

Key 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.
• Researching next generation requirements and features with a view to enable future products.

Required Qualifications

• 10+ years of extensive experience leading architectural efforts in OOO superscalar CPU designs with a track record of successful delivery. Demonstrated ability to define and drive micro-architecture decisions, optimizing performance, power, and area.
• Expert-level understanding of CPU mirco-architectures, memory hierarchy, and coherency in multi-core systems.
• Excellent understanding of SoC design principles and the integration of accelerators, CPUs, and memory subsystems.
• Extensive experience in utilizing advanced functional and performance simulators for architecture exploration, validation, and performance projection, including modeling complex software workloads.
• Additional areas of interest:
• Knowledge of RISC-V architecture, hardware and software aspects.
• Experience with closely coupled accelerators.
• Familiarity with AI/ML software frameworks and their mapping onto hardware.
