Staff Engineer, AI Object Storage

The role

As a Staff Engineer, AI Object Storage, you will design and implement distributed storage solutions to support scaling data-intensive AI workloads. You will contribute directly to the development of exabyte-scale, S3-compatible object storage and integrate dedicated clusters into diverse customer environments. Operating across hardware-adjacent stacks, you will leverage technologies like RDMA, GPU Direct Storage, and distributed filesystem protocols (e.g., NFS, FUSE) to optimise throughput, tail latency, and overall efficiency.

Additionally, you will lead cross-functional efforts to elevate reliability, durability, security, and telemetry metrics while establishing operational best practices, architectural standards, and technical mentorship across the engineering team.

What you will do

The Storage Engine Team at CoreWeave is responsible for the product capabilities and data plane function of CoreWeave’s managed storage products. We build reliable, scalable storage solutions with segment-leading performance, collaborating across infrastructure, compute, and platform teams to meet the needs of the world’s most demanding AI workloads.
