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
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 have not worked on performance-sensitive distributed systems.
  • You want a coordination-heavy role rather than deep technical ownership.
