Staff Backend Engineer Jobs in Raleigh, NC (NOW HIRING)

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.

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.

• 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

• 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 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

• 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

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.
