Job Description

NVIDIA Aerial CUDA Accelerated RAN (ACAR) is framework for building high-performance, software-defined, cloud-native Radio Access Network functions over NVIDIA CPU/GPU/DPU based systems. We are seeking a self-motivated senior performance engineer to drive performance and scalability of our platform. This position offers the opportunity to work on cutting-edge technology for 5G and 6G networks, using NVIDIA's world-class compute platforms to advance the field of software-defined digital signal processing stack!

What you'll be doing:

As a member of Aerial RAN team working for 5G and 6G networks, you will be responsible for:

Developing new Features for Aerial L1 and L2 Software Optimizing CPU, GPU and NIC sub-systems for predictable low-latency and maximum efficiency Crafting and implementing performance verification tools, frameworks and dashboards Monitoring and prioritizing performance regressions reported by CI/CD Collaborating with multi-functional teams to solve performance bottlenecks in CPU, GPU and NIC sub-systems Benchmarking performance use-cases on different platforms

What we need to see:

BS/MS (or equivalent experience) in a relevant field and 12+ years' experience or PhD with 7+ years' experience or equivalent. Strong software design, development, debugging and testing skills. Hands-on experience with performance analysis, characterization and optimization. Experience with programming latency sensitive, real-time, multi-threaded applications on CPUs and one or more of GPUs or DSPs or Vector processors. Deep knowledge of CPU, DSP or GPU architecture, as well as memory, I/O and networking interfaces. Familiarity with data science and using visualization tools to summarize large quantities of data. Experience in one or more programming / scripting languages: C/C++, Python, shell scripting.

Ways to stand out

from the crowd
