Overview

If you enjoy building deep infrastructure systems where networking, storage, kernel behavior, and performance all intersect — this is the kind of role that rarely comes along.

At DDN, we build infrastructure for some of the world’s most demanding AI, HPC, and large-scale data environments. We are looking for a Senior / Staff Fuse Developer who wants to work close to the systems layer — where file systems, object storage, RDMA networking, and Linux kernel behavior directly impact performance at scale.

This is not a role for someone who only consumes infrastructure. It is for engineers who understand how data moves through the stack, who care about latency and throughput, and who enjoy solving hard systems problems deep inside storage and Linux environments.

Job Description

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

Salary Range: $150,000 - $250,000

DDN

Why DDN - DDN is where serious infrastructure engineers go to work on serious data problems.

If you want to work at the intersection of Linux systems, distributed storage, networking, and high-performance infrastructure — and you want to do it in an environment that values technical depth — this is a rare opportunity to build systems operating at massive scale.

Apply if - You are a Bay Area or RTP based engineer with deep systems and infrastructure expertise, and you want to help build the storage and infrastructure platforms behind modern AI and high-performance computing environments.
