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
