Senior Software Engineer — File System Engineering | File System Team | Full-Time | US Boston/Marlborough – Hybrid 3 days Role Overview Nasuni is looking for a Senior Software Engineer to join our File System team and help build the next generation of Nasuni’s storage platform, including core work on Strider and CUFS, Nasuni’s distributed file system. This role is for an engineer who enjoys working deep in the stack: high-performance C/C++, file system semantics, distributed storage, protocol behavior, snapshots, caching, recovery, and Kubernetes-based infrastructure. You will design and deliver production-grade components that directly affect reliability, performance, availability, and customer trust. This role is not a fit for someone focused primarily on application-layer feature development or someone who has only used distributed systems without designing, debugging, or operating them in production. Level & Scope Definition You will independently own complex subsystems within the File System team, make technical decisions within your areas of ownership, and lead design discussions for storage and data path components. You will collaborate closely with Platform, Control Plane, CI/CD, QA, and SRE-oriented teams to ensure software is reliable, observable, upgradeable, and supportable in customer environments. You are expected to balance hands-on execution with technical leade
