Senior/Staff Fuse Developer

Data Direct Networks • Raleigh, NC

22h • $150,000 - $250,000

About The Position

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.

Requirements

• 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

Nice To Haves

• 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

Responsibilities

• 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
