Staff Engineer, Storage Engine

What You'll 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. The storage engine works with engineering teams across infrastructure, compute, and platform to ensure our storage services meet the needs of the world’s most demanding AI workloads.

About the role:

As a Staff Storage Engineer, you will design and implement distributed storage solutions to support scaling data-intensive AI workloads. You will contribute to the development of exabyte-scale, S3-compatible object storage and integrate dedicated storage clusters into diverse customer environments. Operating across hardware‑adjacent stacks, you will leverage technologies such as RDMA, GPU Direct Storage, and distributed filesystem protocols like NFS or FUSE to optimize platform performance and efficiency.

You will lead cross‑functional efforts to improve reliability, durability, security, and telemetry metrics while analyzing system data to drive improvements in throughput and latency. Additionally, you will establish operational best practices, set high architectural standards, and mentor engineers on building high-performance distributed systems.

Who You Are:

• 8–10+ years of experience working in storage systems engineering or infrastructure platforms.
• Strong hands‑on experience with object storage or distributed filesystems in high‑scale production environments.
• Deep experience with one or more storage protocols (e.g., S3, NFS) and distributed file systems such as Ceph, DAOS, or similar.
• Proficiency in a systems programming language such as Go, C, or Rust.
• Experience working with cloud‑native infrastructure, Kubernetes, and scalable system architectures.
• Familiarity with storage observability tools, metrics collection, and telemetry pipelines (e.g., ClickHouse, Prometheus, Grafana).
• Proficiency leveraging AI tools to augment and accelerate software development workflows.
• Bachelor’s, Master’s, or PhD degree in Computer Science, Engineering, or a related technical field.
