About The Role

Training and inference at CoreWeave's scale depend on storage keeping thousands of GPUs fed. As a Senior Specialist Field Engineer for Storage, you'll help customers get the most from shared file storage, object storage, local NVMe, and dedicated storage built for a single customer. You'll work closely with the Storage product and engineering teams, and what you learn in the field will help shape what they build.

In This Role, You Will

• Design storage architecture for complex customers (shared filesystems, object storage, caching, multi-tenant isolation, cross-region data), including how it fails and what each failure affects.
• Troubleshoot problems from the application's I/O pattern down through the NFS client, the CSI driver, the storage network, and the storage cluster itself.
• Find where the product falls short for real workloads and work the gap through with engineering, as an extended member of the Storage team.
• Lead customer technical overviews, proofs of concept, and customer workshops, with occasional travel.

Who You Are

• B.S. in Computer Science or a related technical discipline, or equivalent experience.
• 7+ years building or operating large-scale storage systems, as a storage, systems, or software engineer, or in a deeply technical storage-focused field role.
• Solid working knowledge of NFS (v3 and v4, mount options such as nconnect, failure modes) and S3-compatible object storage.
• Hands-on experience with a distributed or parallel filesystem such as VAST, WEKA, Lustre, or Spectrum Scale.
• Deep understanding of Kubernetes storage: CSI drivers, PVs, PVCs, and StorageClasses, and how to troubleshoot them.
• Very comfortable benchmarking with tools like fio and reading the results, and telling a metadata-bound workload from a bandwidth-bound one.
• You explain technical problems clearly to engineers and executives, and you build trust with customers.

Bonus Points

• Debugging NFS over TCP at scale, including storage problems that turn out to be network problems (retransmits, stale routes, overlay versus underlay).
• Experience with storage for AI workloads: streaming training data, checkpointing at scale, and read caching.
• Diagnosing failures that only show up at scale, such as lock exhaustion under heavy concurrency or rename races corrupting checkpoints.
• Comfortable reading storage system source code to tie production behavior to the code, and able to fix small bugs.
• Contributions to storage open source (kernel NFS, Lustre, Ceph, CSI drivers) or published work on filesystem design or storage performance.

You’ll fit here if...

• You'd rather measure the I/O pattern than guess at it.
• You're comfortable saying "I don't know yet," and then you go find out.
• You like working on a hard problem alongside the customer and the engineering team, and you share the credit.

Wondering if you're a good fit?

We believe in investing in our people, and value candidates who bring their own experiences to our teams - even if you aren't a 100% skill or experience match. If some of this describes you, we'd love to talk.

• You love to help solve challenging technical problems
• You’re curious about the latest and greatest technologies in the AI space
• You’re an expert in managing conflict and achieving mutually beneficial technical outcomes
