The GPU Cache Design Verification Engineer is responsible for the pre-silicon RTL verification of cache hierarchy and related units in a low power GPU design. This includes deep understanding of the micro-architectural details of these units, interactions between the units, and the connection of the uarch to the larger architectural intent of the GPU. A strong computer architecture background, experience in cache and memory subsystem verification, software engineering skills, and a proven foundation in verification methodology will be used to close testing coverage with high confidence.

Key Qualifications
Solid understanding of computer and cache architecture
Experience developing a unit or subsystem testing environment from start to closure
Experience with memory/cache sub-system micro-architecture, which could include multiple levels of cache, coherent interconnects, MMUs or related blocks is a plus
Expertise in crafting software solutions applying object oriented programming concepts, preferably with SystemVerilog
Experience with a verification methodology such as UVM/OVM, and a hardware description language such as Verilog/VHDL
Experience with HDL simulators and waveform viewers
Experience defining coverage space, writing coverage models, and analyzing results
Proven success working under strict schedule deadlines with the ability to manage multiple priorities
Excellent interpersonal skills and ability to collaborate
GPU experience, especially in the cache/memory hierarchy area, is a plus

Description
As a GPU Cache Hierarchy Design Verification Engineer, you will be responsible for:
- Owning testing of major features and collaborating with other block and core level engineers to ensure flawless verification flow
- Developing verification plans in coordination with design leads and architects
- Architecting, building and maintaining verification test bench components and environments to validate architectural correctness of the design
- Generating directed and constrained random tests
- Running simulations and debugging design and environment issues
- Crafting functional coverage points, analyze coverage, and improve test environment to target coverage holes
- Crafting automated verification flows for block verification
- Applying knowledge of hardware description languages (VHDL/Verilog), hardware verification languages/frameworks (SystemVerilog/UVM/OVM), and logic simulators to verify sophisticated designs
- Mentoring junior engineers to grow their skillsets

Education & Experience
BS + minimum of 3 years of experience
