What You'll Do: The Storage Engineering team builds, scales, and operates CoreWeave's high-performance AI storage platform. We design reliable, high-throughput storage systems engineered natively for hyperscale cloud environments, providing the storage backbone that powers some of the largest and most innovative AI workloads in the world. About the role: As a Senior Engineer, AI Object Storage, you will play a key role in designing, building, and operating the multi-tenant control plane for our high-performance AI storage platform. You will contribute directly to the development of exabyte-scale, S3-compatible object storage and distributed file systems, integrating dedicated clusters into diverse customer environments. This role requires partnering cross-functionally across infrastructure, compute, and platform teams to implement automated storage capabilities. You will work closely with hardware-adjacent technologies-including RDMA, GPU Direct Storage, RoCE, InfiniBand, and SPDK-to optimize tail latency and durability, while mentoring other engineers on best practices for high-performance distributed systems. Who You Are: 6–10 years of experience working in storage systems engineering or infrastructure operations. Strong hands-on experience with object storage or distributed file systems in production environments. Deep experience with one or more storage protocols (e.g., S3, NFS) and distributed architectures like Ceph, DAOS, or similar. Proficiency in a systems programming language such as Go, C, or Rust. Solid understanding of cloud-native infrastructure, Kubernetes, and scalable system architecture. Familiarity with storage observability tools, telemetry pipelines, and open-source data stacks (e.g., ClickHouse, Prometheus, Grafana). Strong debugging and problem-solving skills in distributed, high-performance environments under pressure. Clear communicator, able to work collaboratively across global teams and share technical insights effectively. Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field. Wondering if you're a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams even if you aren't a 100% skill or experience match. Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk. You love to build clarity out of complex architectural problems and champion robust, automated multi-tenant control planes from concept to production. You're curious about pioneering low-latency storage optimizations and pushing the boundaries of exabyte-scale distributed data platforms. You're an expert in high-performance systems engineering, optimizing cloud-native storage protocols, and mentoring peers on technical best practices. Why CoreWeave?
