Staff Engineer AI​/ML

Global Foundries is a leading full-service semiconductor foundry that provides design, development, and fabrication services. With the addition of the MIPS team, we now offer a rich portfolio of RISC-V CPUs, especially AI-enabled processors for the Physical AI world.

We are seeking an experienced CPU IP Design Engineer. The engineer will define, lead, and own the RTL development of our latest AI-enabled RISC-V CPU core, handling all aspects of the design, including functional features, performance, power, and area.

• Drive the micro-architecture and design of critical blocks of the CPU core.
• Design the RISC-V Vector CPU core and its custom extensions.
• Design an AI-enabled matrix engine to augment the Vector CPU.
• Explore high-performance strategies with the CPU modeling team.
• Perform microarchitecture development and specification from high-level architectural exploration through detailed specifications.
• Configure design features and develop, assess, and refine RTL design to target power, performance, area, and timing goals.
• Perform functional verification support and assist with the design verification strategy.
• Assist in the verification of RTL design performance goals.
• Partner with a multi-functional engineering team to implement and validate physical design aspects of timing, area, reliability, testability, and power.

• Hands-on working knowledge of the pipeline stages of an in-order or out-of-order high-performance CPU core.
• Thorough knowledge of microprocessor architecture, including expertise in instruction fetch and decode, branch prediction, instruction scheduling, register renaming, reorder buffer, out-of-order execution, integer and floating-point execution, load/store execution, instruction and data prefetch, vector datapath, cache and memory subsystems, and cache coherency and memory consistency.
• Knowledge of System Verilog, Verilog and/or VHDL.
• Experience with simulators and waveform debugging tools.
• Knowledge of logic design principles along with timing and power implications.
• Master’s degree with 4–7 years of experience or PhD with 2–5 years of experience.

• Experience designing RISC-V, ARM, and/or MIPS CPUs.
• Experience with hardware multi-threading, virtualization, and SIMD designs.
• Experience with vector and matrix-enabled CPUs, preferably RISC-V processors.
• Understanding of high-performance techniques and trade-offs in a CPU microarchitecture.
• Understanding of low-power microarchitecture techniques.
• Experience using a scripting language such as Perl or Python.
• Understanding of CPU integration at SoC level.
• Understanding of safety and security microarchitecture.
