Why this role is compelling At DDN, you will work on infrastructure challenges that sit at the core of modern high-performance systems: Building and optimizing FUSE-based file system technologies Working across Linux kernel file systems and user-space infrastructure layers Designing high-performance infrastructure for distributed storage environments Improving how object storage systems behave under real production workloads Working with RDMA networking principles and high-speed data movement Solving performance bottlenecks across networking, storage, and I/O pathways Developing systems-level infrastructure in C and C++ Building platforms that support AI, HPC, and large-scale data-intensive workloads Your work will directly influence how large-scale infrastructure platforms perform in real-world production environments — not just in theory. What you’ll do Design, build, and optimize FUSE-based infrastructure and storage components Develop and improve Linux file system integrations across kernel and user-space layers Work on distributed storage and object storage infrastructure systems Improve scalability, resiliency, and performance across storage platforms Optimize networking and data movement using RDMA principles Diagnose bottlenecks across file systems, networking, memory, and I/O stacks Develop infrastructure tooling and platform capabilities in C and C++ Work closely with systems, storage, and platform engineering teams on deeply technical infrastructure challenges Help shape next-generation infrastructure platforms for AI and high-performance environments What we’re looking for Strong hands-on experience developing with FUSE and Linux file systems Deep understanding of Linux kernel file system architecture Strong programming skills in C and C++ Strong understanding of POSIX file system principles Experience with object storage systems and distributed infrastructure Familiarity with RDMA networking principles and high-speed networking technologies Experience working close to kernel-space and user-space I/O paths Strong systems mindset with the ability to debug complex infrastructure and performance issues Experience building or optimizing infrastructure platforms in production environments You’ll thrive here if You enjoy low-level systems and infrastructure engineering You care deeply about performance, scale, and reliability You like solving technical problems that most engineers avoid because they are too deep or performance-sensitive You enjoy understanding how storage and networking behave under pressure You prefer working close to the metal instead of purely abstracted application layers You want to build infrastructure that directly powers mission-critical environments This role is probably not for you if Your background is primarily application-layer or general backend development You have limited experience with Linux internals, file systems, or infrastructure engineering You prefer higher-level platform abstraction over systems-level development You have not worked on performance-sensitive distributed systems You want a coordination-heavy role rather than deep technical ownership
