Overview

We are looking for a Senior HPC and AI Network Software Architect to help build the next generation of scalable AI infrastructure.

The role emphasizes distributed training, real-time inference, and communication efficiency across large systems.

You will develop new software and hardware approaches, shape platform evolution through hands‑on innovation, and contribute to designing systems that power the fastest AI workloads globally.

Responsibilities

  • Build and evolve the architecture of scalable software systems for distributed AI training and inference, focusing on throughput, latency, resiliency, and memory efficiency across cluster-scale deployments.
  • Develop and evaluate next‑generation communication and runtime capabilities in libraries such as NCCL, UCX, and UCC, tailored to the evolving demands of frontier AI workloads.
  • Partner with AI framework teams (e. g., Tensor Flow, Py Torch, JAX) and internal platform teams to build integrations, explore new approaches, and improve end‑to‑end performance and reliability.
  • Collaborate on hardware and system‑level features across GPUs, DPUs, and interconnects to speed up data movement and enable new capabilities for training, inference, and model serving at scale.
  • Drive innovation across runtime systems, communication libraries, and AI‑specific protocol layers, helping turn new ideas into practical capabilities and robust implementations.

Qualifications

  • Ph. D., or equivalent industry experience, in computer science, computer engineering, or a closely related field.
  • 5+ years of experience in systems programming, parallel or distributed computing, high‑performance networking, or large‑scale data movement, including experience designing and building complex systems.
  • Strong programming background in C++, Python, and ideally CUDA or other GPU programming models, with a track record of building production‑quality performance‑critical software.
  • Extensive hands‑on experience with AI frameworks (e. g., Py Torch, Tensor Flow, JAX) and a solid grasp of how communication libraries and runtime systems facilitate large‑scale training and inference.
  • Demonstrated success in developing and refining high‑throughput, low‑latency systems, including the ability to reason across software stacks, hardware capabilities, and system bottlenecks.
  • Strong collaboration skills in a multi‑national, interdisciplinary setting, with the ability to contribute ideas, build momentum, and work effectively with senior engineers, researchers, and partner teams.
  • Ways to Stand Out
  • Deep expertise with NCCL, UCX, UCC, or similar communication libraries used in large‑scale AI and HPC workloads.
  • Strong background in networking and communication protocols, RDMA, collective communications, congestion‑aware transport, or accelerator‑aware networking.
  • Comprehensive knowledge of large model training and inference serving at scale, including communication bottlenecks, scheduling challenges, and system‑level tradeoffs across compute, memory, and fabric.
  • Experience crafting hardware‑software co‑design for distributed AI systems, including contributions that advanced GPU, DPU, interconnect, or runtime capabilities.
  • Familiarity with infrastructure for deployment of LLMs or transformer‑based models, including sharding, pipelining, expert parallelism, or hybrid parallelism.

How to prepare for a job interview at NVIDIA AI

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If NVIDIA AI uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Showcase Your Projects

Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
