If you enjoy building deep class="bg-amber-100">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 class="bg-amber-100">infrastructure for some of the world’s most demanding AI, HPC, and large-scale class="bg-amber-100">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 class="bg-amber-100">Linux kernel behavior directly impact performance at scale.

This is not a role for someone who only consumes class="bg-amber-100">infrastructure. It is for engineers who understand how class="bg-amber-100">data moves through the stack, who care about latency and throughput, and who enjoy solving hard systems problems deep inside storage and class="bg-amber-100">Linux environments.

Job Description

Why this role is compelling

At DDN, you will work on class="bg-amber-100">infrastructure challenges that sit at the core of modern high-performance systems:

• Building and optimizing FUSE-based file system technologies
• Working across class="bg-amber-100">Linux kernel file systems and user-space class="bg-amber-100">infrastructure layers
• Designing high-performance class="bg-amber-100">infrastructure for distributed storage environments
• Improving how object storage systems behave under real production workloads
• Working with RDMA networking principles and high-speed class="bg-amber-100">data movement
• Solving performance bottlenecks across networking, storage, and I/O pathways
• Developing systems-level class="bg-amber-100">infrastructure in C and class="bg-amber-100">C++
• Building platforms that support AI, HPC, and large-scale class="bg-amber-100">data-intensive workloads
  
  

Your work will directly influence how large-scale class="bg-amber-100">infrastructure platforms perform in real-world production environments — not just in theory.

What You’ll Do

• Design, build, and optimize FUSE-based class="bg-amber-100">infrastructure and storage components
• Develop and improve class="bg-amber-100">Linux file system integrations across kernel and user-space layers
• Work on distributed storage and object storage class="bg-amber-100">infrastructure systems
• Improve scalability, resiliency, and performance across storage platforms
• Optimize networking and class="bg-amber-100">data movement using RDMA principles
• Diagnose bottlenecks across file systems, networking, memory, and I/O stacks
• Develop class="bg-amber-100">infrastructure tooling and platform capabilities in C and class="bg-amber-100">C++
• Work closely with systems, storage, and platform engineering teams on deeply class="bg-amber-100">technical class="bg-amber-100">infrastructure challenges
• Help shape next-generation class="bg-amber-100">infrastructure platforms for AI and high-performance environments
  
  

What we’re looking for

• Strong hands-on experience developing with FUSE and class="bg-amber-100">Linux file systems
• Deep understanding of class="bg-amber-100">Linux kernel file system architecture
• Strong class="bg-amber-100">programming skills in C and class="bg-amber-100">C++
• Strong understanding of POSIX file system principles
• Experience with object storage systems and distributed class="bg-amber-100">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 class="bg-amber-100">infrastructure and performance issues
• Experience building or optimizing class="bg-amber-100">infrastructure platforms in production environments
  
  

You’ll thrive here if

• You enjoy low-level systems and class="bg-amber-100">infrastructure engineering
• You care deeply about performance, scale, and reliability
• You like solving class="bg-amber-100">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 class="bg-amber-100">infrastructure that directly powers mission-critical environments
  
  

This role is probably not for you if

• Your background is primarily application-layer or general class="bg-amber-100">backend development
• You have limited experience with class="bg-amber-100">Linux internals, file systems, or class="bg-amber-100">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 class="bg-amber-100">technical ownership
  
  

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

DDN

Why DDN - DDN is where serious class="bg-amber-100">infrastructure engineers class="bg-amber-100">go to work on serious class="bg-amber-100">data problems.

If you want to work at the intersection of class="bg-amber-100">Linux systems, distributed storage, networking, and high-performance class="bg-amber-100">infrastructure — and you want to do it in an environment that values class="bg-amber-100">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 class="bg-amber-100">infrastructure expertise, and you want to help build the storage and class="bg-amber-100">infrastructure platforms behind modern AI and high-performance computing environments.
