About The Position

Crusoe is hiring a Senior Software Engineer for its storage team to design, build, and optimize next-generation cloud storage products. The engineer will build highly performant, reliable, and scalable distributed storage systems that support Crusoe’s infrastructure and customers’ AI/HPC workloads. The role focuses on developing core components of a multi-petabyte cloud storage platform and foundational storage products designed for high-performance AI and ML workloads. It includes contributing to distributed file, block, and object storage products, with an emphasis on filesystem-based solutions; designing extensible, scalable, resilient storage architectures; prototyping strategies to improve performance and throughput; and building observability, metrics, and tooling. The engineer will troubleshoot complex distributed-systems issues at Crusoe’s scale, support production systems and customer workloads through troubleshooting, performance tuning, and incident response, and collaborate with engineering and cross-functional teams. The role also has single-threaded ownership and represents the storage team in business-critical company initiatives.

Requirements

Hands-on proficiency in modern software development best practices and practical experience with languages such as Go, Java, C/C++, or Rust.
Extensive experience developing multi-tenant, cloud-scale distributed storage infrastructure software and systems.
Experience contributing to at least one or more file, object, or block storage products, such as NFS, SMB, Lustre, NVMe, or iSCSI.
Strong background in high-performance filesystem-based products, VFS, and Linux filesystems such as ext4, XFS, or ZFS.
Proficiency working with Linux and its storage subsystems.
Knowledge of monitoring tools such as Prometheus and Grafana, log analysis, distributed tracing, and debugging.

Nice To Haves

Experience with AI/HPC storage solutions, such as parallel filesystems or petabyte-plus-scale object storage.
