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
