Ddn Senior Staff Engineer - AI Data Path at DDN leads design and implementation of high-performance data movement pipelines integrating GPU and storage tiers. The role focuses on optimizing I/O paths and multi-tier storage architectures for AI inference workloads.

Responsibilities

Lead the design and implementation of high-performance data movement pipelines using NVIDIA NIXL across GPU, CPU, and storage tiers.
Architect and drive integration of DDN Infinia with GPU-accelerated inference platforms for large-scale, real-time AI workloads.
Own end-to-end optimization of I/O paths between GPU memory and storage using technologies such as NVIDIA GPUDirect Storage, RDMA, and NVMe-over-Fabrics.
Define and implement multi-tier storage architectures (NVMe, SSD, object storage) optimized for inference latency, throughput, and scalability.
Lead development of advanced KV cache management strategies, including offloading, prefetching, and persistence across distributed storage layers.
Partner with AI/ML engineering teams to optimize inference performance in frameworks such as PyTorch and TensorFlow.
Establish benchmarking frameworks and lead performance tuning efforts for storage and data movement in production inference environments.
Diagnose and resolve complex system bottlenecks across storage, networking, and GPU subsystems.
Influence architecture decisions for distributed inference systems, ensuring scalability, resilience, and efficient data locality.
Drive engineering excellence through best practices in observability, performance monitoring, automation, and reliability engineering.
Mentor junior engineers and provide technical leadership across cross-functional teams.
Leading the evolution of storage systems into GPU-native data layers for AI inference
