Linux Kernel Developer Jobs in Oregon (NOW HIRING)

Do you want to help drive the development of CPU architectures to fuel the explosive growth in artificial intelligence (AI) / deep learning (DL), high-performance computing (HPC), gaming, virtual reality, and autonomous vehicles? Come join the CPU performance architecture team as a Senior System Simulation Architect and help us push performance boundaries for NVIDIA's line of CPU products!

What you'll be doing:

• Develop full-system functional models capable of running complex multi-threaded heterogeneous (CPU/GPU) workloads - with special focus on the CPU subsystem.

• Integrate functional models from various frameworks with RTL simulators and emulators, hardware (HW-in-the-loop), and detailed performance models.

• Bring up system and application software in simulation and emulation - including firmware, Linux, drivers, benchmarks, and CPU/GPU workloads such as deep-learning (DL) and high-performance computing (HPC) workloads.

• Port/extend/develop system software (firmware, OS, and drivers) to meet workload simulation needs.

• Support CPU architects and performance engineers in their use of functional models, performance models, and emulation to drive next-generation CPU architectures.

What we need to see:

• BS/MS in EE, CE, or CS or equivalent experience

• 6 or more years of relevant experience

• Excellent C/C++/Python programming skills

• Experience in development of functional simulators and/or low-level software (OS, firmware, drivers); preferably both

• Excellent debugging skills - of both system software/firmware and application software

• Experience with the ARM ISA

• Excellent communication and teamwork skills

Ways to stand out from the crowd:

• Experience working with hardware emulators and/or FPGAs

• Background in CPU workload analysis (SimPoint, etc.)

• Experience with Linux kernel bringup and debug

• Familiarity with CUDA

• Experience with CPU/GPU application development and optimization in Pytorch, TensorFlow, and similar frameworks
