Staff Engineer, AI Object Storage Location: Warsaw, Poland 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, collaborating across infrastructure, compute, and platform teams to meet the needs of the world’s most demanding AI workloads. About the role: As a Staff Engineer, AI Object Storage, you will design and implement distributed storage solutions to support scaling data-intensive AI workloads. You will contribute directly to the development of exabyte-scale, S3-compatible object storage and integrate dedicated clusters into diverse customer environments. Operating across hardware-adjacent stacks, you will leverage technologies like RDMA, GPU Direct Storage, and distributed filesystem protocols (e.g., NFS, FUSE) to optimise throughput, tail latency, and overall efficiency. Additionally, you will lead cross-functional efforts to elevate reliability, durability, security, and telemetry metrics while establishing operational best practices, architectural standards, and technical mentorship across the engineering team. Who You Are: Bachelor’s, Master’s, or PhD degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience). 8+ years of professional engineering experience 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 storage protocols (e.g., S3, NFS) and distributed architectures 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, metrics collection, and telemetry pipelines (e.g., ClickHouse, Prometheus, Grafana). Proficiency leveraging AI tools to augment and accelerate software development workflows. 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. You love to: Grow continuously, push the boundaries of your technical expertise, and solve complex distributed platform challenges.
