Senior Full Stack Developer

Why This Role Is CompellingAt DDN, you will work on infrastructure challenges that sit at the core of modern high-performance systems:Building and optimizing FUSE-based file system technologiesWorking across Linux kernel file systems and user-space infrastructure layersDesigning high-performance infrastructure for distributed storage environmentsImproving how object storage systems behave under real production workloadsWorking with RDMA networking principles and high-speed data movementSolving performance bottlenecks across networking, storage, and I/O pathwaysDeveloping systems-level infrastructure in C and C++Building platforms that support AI, HPC, and large-scale data-intensive workloadsYour work will directly influence how large-scale infrastructure platforms perform in real-world production environments — not just in theory.What You'll DoDesign, build, and optimize FUSE-based infrastructure and storage componentsDevelop and improve Linux file system integrations across kernel and user-space layersWork on distributed storage and object storage infrastructure systemsImprove scalability, resiliency, and performance across storage platformsOptimize networking and data movement using RDMA principlesDiagnose bottlenecks across file systems, networking, memory, and I/O stacksDevelop infrastructure tooling and platform capabilities in C and C++Work closely with systems, storage, and platform engineering teams on deeply technical infrastructure challengesHelp shape next-generation infrastructure platforms for AI and high-performance environmentsWhat We're Looking ForStrong hands-on experience developing with FUSE and Linux file systemsDeep understanding of Linux kernel file system architectureStrong programming skills in C and C++Strong understanding of POSIX file system principlesExperience with object storage systems and distributed infrastructureFamiliarity with RDMA networking principles and high-speed networking technologiesExperience working close to kernel-space and user-space I/O pathsStrong systems mindset with the ability to debug complex infrastructure and performance issuesExperience building or optimizing infrastructure platforms in production environmentsYou'll Thrive Here IfYou enjoy low-level systems and infrastructure engineeringYou care deeply about performance, scale, and reliabilityYou like solving technical problems that most engineers avoid because they are too deep or performance-sensitiveYou enjoy understanding how storage and networking behave under pressureYou prefer working close to the metal instead of purely abstracted application layersYou want to build infrastructure that directly powers mission-critical environmentsThis Role Is Probably Not For You IfYour background is primarily application-layer or general backend developmentYou have limited experience with Linux internals, file systems, or infrastructure engineeringYou prefer higher-level platform abstraction over systems-level developmentYou have not worked on performance-sensitive distributed systemsYou want a coordination-heavy role rather than deep technical ownership
