Staff Engineer AI/ML

Job Title

Staff Engineer AI/ML

Role Summary

Lead RTL development for an AI-enabled RISC-V CPU core within the MIPS team at GlobalFoundries. Own microarchitecture, RTL implementation, and cross-functional validation to meet performance, power, area and timing targets.

Experience Level

Senior. The posting indicates typical experience levels: Masters degree with 10+ years' experience or PhD with 5+ years' experience.

Responsibilities

Primary responsibilities include CPU microarchitecture, RTL development, verification support, and collaborative integration into SoC and physical design flows.

• Drive micro-architecture and design of critical CPU core blocks.
• Design RISC-V vector CPU core and its custom extensions.
• Design AI-enabled matrix engine to augment the vector CPU.
• Perform high-level architectural exploration and produce detailed microarchitecture specifications.
• Develop, assess, and refine RTL to meet power, performance, area, and timing objectives.
• Support functional verification and contribute to verification strategy and performance validation.
• Collaborate with modeling, verification, and physical design teams on timing, area, reliability, testability, and power.
• Adhere to Environmental, Health, Safety & Security requirements.

Requirements

Must-have technical skills and experience.

• Hands-on experience with high-performance processors, vector processors, or GPUs.
• Datapath design experience including vector and matrix processing for floating-point and integer datatypes.
• Deep knowledge of microprocessor architecture (fetch/decode, branch prediction, instruction scheduling, register renaming, ROB, out-of-order execution, integer/FPU execution, load/store units, prefetching, vector datapaths, cache and memory subsystems).
• Proficiency in SystemVerilog, Verilog and/or VHDL.
• Experience with simulators and waveform debugging tools.
• Understanding of logic design principles and timing and power trade-offs.
• Experience supporting RTL verification and working with verification teams.
• Ability to work cross-functionally to integrate CPU IP into SoC and physical design flows.

Preferred / nice-to-have:

• Experience designing RISC-V, ARM, and/or MIPS CPUs.
• Experience with hardware multithreading, virtualization, SIMD, or vector/matrix-enabled CPUs.
• Familiarity with low-power microarchitecture techniques and CPU integration at SoC level.
• Scripting experience (Perl, Python) and understanding of safety/security microarchitecture.

Education Requirements

Masters degree with 10+ years of relevant work experience, or PhD with 5+ years of relevant work experience. Specific fields of study were not specified.
