Quantum is listed on Nasdaq (QMCO). For more information, visit www.quantum.com.\nWe are seeking a Senior Object Storage Software Engineer to design, implement, and optimize the object storage data path and core distributed services of our scale-out object storage platform. You will own software from the moment an object request hits the network interface through request processing, metadata operations, data placement, and durable persistence across the cluster.\nThis is a deep systems role for engineers passionate about low-latency code paths, high concurrency, and distributed systems correctness at scale.\nKey Responsibilities\nObject Storage Data Path\nDesign and optimize the object request pipeline for PUT/GET/DELETE and background operations, focusing on predictable latency, high throughput, and efficient CPU/memory usage in the critical path.\nBuild and maintain data path components such as request parsing/validation, routing, throttling, buffering, streaming I/O, and zero-copy / reduced-copy transfers where applicable.\nImplement and tune distributed caching (read cache / metadata cache) and request coalescing strategies to reduce backend amplification and improve tail latency.\nIdentify and eliminate bottlenecks end-to-end (network CPU storage), leveraging deep Linux profiling and systems debugging skills.\nCore Object Services & Distributed Architecture\nArchitect and evolve scale-out services for object metadata, namespace/indexing, placement, and cluster membership/state required for large clusters.\nDesign and maintain scalable, high-performance components such as metadata management and data placement algorithms across multi-node deployments.\nDurability, Integrity & Resilience\nImplement and maintain durability features such as erasure coding, replication, background healing, snapshots (where applicable), thin provisioning concepts, and data scrubbing to deliver “six nines” class durability.\nEnsure correctness under failures: node loss, disk faults, partial writes, network partitions, and rolling upgrades—without compromising data integrity.\nConcurrency, Locking & Correctness\nSolve high-concurrency challenges in the object and metadata paths using robust synchronization strategies, lock minimization, and asynchronous execution models to maximize multi-core CPU utilization.\nApply careful correctness reasoning around ordering, idempotency, and race conditions in distributed request flows.\nScalability & Cluster Operations\nEnsure the object data path and background systems scale linearly as nodes are added, including rebalancing and reconstruction workflows that minimize customer-visible impact.\nCollaborate cross-functionally to integrate other platform components into the solution and operate effectively with remote teams.\nRequired Qualifications\n12+ years of software development experience using C/C++, Rust (or equivalent systems-level expertise).\nStrong experience with distributed systems and high-performance storage software design.\nStrong Linux experience, including debugging, profiling, and performance analysis of complex systems.\nSolid understanding of concurrency, locking, and asynchronous programming models.\nStrong communication skills; ability to collaborate in a team environment and across functions; ability to work effectively with remote teams.\nSelf-motivated, able to identify and solve problems independently, creative problem-solving mindset.\nWilling and able to come to our office in Centennial, CO during core business hours (Tuesday - Thursday 10am-4pm).\nPreferred / Nice-to-Have Skills\nExperience with the Linux I/O subsystem and networking (plus).\nExperience with storage protocols, clustering design and development (plus).\nExperience with containers and Kubernetes (plus).\nExperience using Git and Jira.\nExperience with Amazon AWS S3 API, SDK’s & Tools.\nExperience with AI tools or programming is a plus (especially for modern data pipelines and workload integration).\nQuantum provides a diverse portfolio of health plans for medical and prescription, dental, vision, life, disability, and supplemental medical insurance options.
