Senior Storage Engineer, File & Block

CoreWeave is The Essential Cloud for AI. We're looking for a Senior Storage Engineer, File & Block to help build and operate the file and block storage services at the heart of CoreWeave's Storage team.

What You'll Do:

You'll help turn CoreWeave's storage from a follower of GPU growth into a multiplier of it: owning the data path and control plane for both file and block, running them on our own hardware fleet, and shipping the customer-facing capabilities that unblock petabyte-scale deals.

Responsibilities:

• Design, build, and operate highly scalable, multi-tenant file and block storage , from the data path to the control plane that governs tenancy, provisioning, and data protection.
• Own the file system data path: NFS hot-path reliability, IO resilience, and performance.
• Build a native block storage service: durable, high-performance block volumes for customer workloads and internal stateful services.
• Deliver both file and block as first-class Kubernetes citizens: design and ship a backend-neutral CSI driver with dynamic provisioning, resize, snapshots, and RWO block volumes.
• Build the control plane: multi-tenant isolation, quota, QoS, snapshots, key management, audit, and lifecycle policy.
• Improve the reliability, durability, and observability of the storage stack; partner with operations to monitor, analyze, and optimize using telemetry, metrics, and dashboards.
• Work cross-functionally with platform, product, and infrastructure teams to deliver seamless storage across the stack.
• Share your knowledge and mentor other engineers on best practices in building distributed, high-performance systems.
• Work with technologies such as RDMA, GPU Direct Storage, RoCE, InfiniBand, SPDK, and distributed filesystems to optimize storage performance and efficiency.

Requirements:

• Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
• 6–10 years building storage systems, distributed systems, or infrastructure services.
• Strong hands-on experience with distributed or networked file systems and/or block storage in production.
• Depth in the storage data path: IO performance, caching, small-file and metadata-heavy workloads, crash consistency, and resilience under load.
• Experience with multi-tenant services or storage control planes , provisioning, tenancy/quota, and data-protection features.
• Proficiency in a systems/back-end language , Go strongly preferred.
• Experience building on Kubernetes , controllers/operators, CRDs, and CSI.
• Familiarity with distributed databases, workflow orchestration, and gRPC/Protobuf service design.

Benefits:

• Medical, dental, and vision insurance - 100% paid for by CoreWeave
• Company-paid Life Insurance
• Voluntary supplemental life insurance
• Short and long-term disability insurance
• Flexible Spending Account
