Senior/Staff Fuse Developer

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
