Senior Staff Engineer - AI Data Path
DDN
DDN is seeking a highly experienced Senior Staff Engineer specializing in AI Data Path & Storage to lead hands-on development and integration of advanced storage systems with next-generation AI inference pipelines. This role involves coding, prototyping, and rapidly iterating on solutions in close collaboration with architects to design and deliver high-performance data movement architectures. You will leverage NVIDIA’s NIXL (Inference Transfer Library) alongside the Infinia Data Intelligence Platform to enable ultra-low-latency, high-throughput data movement across GPU, memory, and distributed storage layers, including workloads involving KV cache management and vector database retrieval. The ideal candidate brings deep expertise in distributed storage, GPU data paths, and large-scale system optimization, with a proven track record of building and shipping production-grade AI infrastructure. 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.
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.
