Systems Software Engineer - Object Storage
About The Position
The Systems Software Engineer will contribute to Quantum’s ActiveScale object-storage software, working across the data path that handles incoming S3 requests and moves data to durable storage across NVMe, HDD, and tape. The role includes implementing and extending S3 API functionality and helping improve I/O latency, throughput, and reliability. The engineer will contribute to durability and data placement, including erasure coding, and help ensure correctness in failure scenarios such as node loss, disk faults, and partial writes. The role also involves improving concurrency and throughput across request and storage paths, and contributing to systems that tier data from NVMe through HDD to ActiveScale Cold Storage tape. The position involves writing clean, well-tested code; developing unit, component, and integration tests; using CI; and participating in design discussions and code reviews. Under guidance from senior engineers, the engineer will grow toward independent ownership of components. This is a hybrid role with in-office work at the Centennial, Colorado office Tuesday through Thursday.
