What You’ll Do:
CoreWeave's Storage team builds the file, block and object storage that the world's largest AI training and inference workloads run on. As a Staff Software Engineer you will own whole storage subsystems end to end, from the data path to the multi-tenant control plane, on distributed systems built in Go, Rust and C++ and delivered through Kubernetes. Storage at CoreWeave sits next to the GPUs, so your work directly determines how fast the largest AI clusters in the world train.
About the role:
You will set technical direction for foundational storage services built from scratch: high-performance file storage, durable block volumes and the control plane that governs tenancy, provisioning and data protection at exabyte scale.
- Own the architecture and delivery of multi-tenant file and block storage services, data path through control plane, running on CoreWeave's own hardware fleet.
- Design for the IO patterns AI pipelines create: small-file and metadata-heavy workloads, IOPS at scale and the sustained throughput that keeps GPUs fed.
- Ship storage as a first-class Kubernetes citizen: CSI drivers, dynamic provisioning, snapshots, resize and RWO block volumes backed by public SLOs.
- Work with technologies such as RDMA, GPU Direct Storage, RoCE, InfiniBand, SPDK and distributed filesystems to raise storage performance and efficiency.
- Drive reliability, durability and observability across the storage stack using telemetry, metrics and dashboards.
- Set the technical bar: lead design reviews, mentor senior engineers and shape how storage is built across the organization.
Who You Are:
- Bachelor's or Master's degree in Computer Science, Engineering or a related field.
- 10+ years of experience in storage systems, database internals or infrastructure engineering.
- A track record of building storage or database systems others rely on: a founding or lead engineer on a shipped storage product, published systems work, or equivalent depth.
- Strong production experience with distributed file systems, block storage or storage engines, including protocols such as NFS or S3 and systems such as Ceph, Lustre or similar.
- Depth in the storage data path: IO performance, caching, crash consistency and resilience under load.
- Expert in a systems programming language: Rust, C++ or Go.
- Experience building on Kubernetes: controllers, operators, CRDs and CSI.
- Strong debugging and problem-solving skills in distributed, high-performance environments.
- Clear communicator, able to work collaboratively across teams and share technical insights effectively
