Job description

NVIDIA Aerial CUDA Accelerated RAN 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 software engineer to drive development, 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 Will Be Doing

• Lead design and development of cutting-edge end-to-end reference system stack for 5G/6G baseband system.
• Optimizing CPU, GPU and NIC sub-systems for predictable low-latency and maximum throughput
• Collaborating with cross-functional teams to troubleshoot performance bottlenecks in CPU, GPU and NIC sub-systems
• Work in lab environment to trouble-shoot and integrate complex software modules.
• Develop software, implementing new baseband functions in C/C++/Python/CUDA on a GPU platform.
• Support system integration, performance testing, system demonstration and lab trials for end-to-end system.
• Be a technical bridge between engineering team and partners/customers engineering team. Engage with customer field trials and technical teams.
• Help in implementing missing features to unblock progress at customers/partners and in benchmarking and develop/evaluate test tools for Aerial SDK evaluation.

What We Need To See

• Our ideal candidate has a wireless communication systems or digital signal processing background, a passion for building real-world carrier-grade communication systems, and industry experience developing PHY/MAC layer or base band unit (BBU) software in C/C++.
• Understanding of the PHY/MAC layer procedures and typical performance tradeoffs, as well as overall system performance.
• Background with LTE/5G MAC and PHY from both systems and low-level 3GPP spec point of view. Ability to switch between high-level systems view and low-level detail view of complex wireless systems.
• Comfortable using wireless lab equipment such as signal generators, network analyzers, power meters, etc. Exposure to CUDA/GPU programming is a plus.
• MS or PhD in Engineering, Mathematics, Physics, Computer Science or Telecommunications (or equivalent experience)
• 8+ years of work-related industry experience in software development, systems engineering.
• Understanding of telecommunications radio device design and implementation in a regulated industry.
• Ability to work as an individual contributor or take a technical leadership role. Strong written and oral communication skills with the ability to effectively collaborate with management and engineering.
• Experience in the telecommunications industry or with customers/partners in the telecommunications domain.
• Strong time-management and organization skills for coordinating multiple initiatives, priorities and implementations of new technology and products into very complex projects. Strong analytical and problem-solving skills.
