Staff Software Engineer, Storage

CoreWeave is The Essential Cloud for AI. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence.

As a Staff Software Engineer on CoreWeave's Storage team, 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.

Your responsibilities will include:

• Setting 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.
• Owning the architecture and delivery of multi-tenant file and block storage services, data path through control plane, running on CoreWeave's own hardware fleet.
• Designing for the IO patterns AI pipelines create: small-file and metadata-heavy workloads, IOPS at scale and the sustained throughput that keeps GPUs fed.
• Shipping storage as a first-class Kubernetes citizen: CSI drivers, dynamic provisioning, snapshots, resize and RWO block volumes backed by public SLOs.
• Working with technologies such as RDMA, GPU Direct Storage, RoCE, InfiniBand, SPDK and distributed filesystems to raise storage performance and efficiency.
• Driving reliability, durability and observability across the storage stack using telemetry, metrics and dashboards.
• Setting the technical bar: leading design reviews, mentoring senior engineers and shaping how storage is built across the organization.

Requirements:

• 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.
• Expertise 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 communication, ability to work collaboratively across teams and share technical insights effectively.
