Job summary

Data Direct Networks is seeking a Senior/Staff Fuse Developer to join on-site in a high-performance storage environment. The role focuses on building and optimizing FUSE-based infrastructure, with close work on Linux kernel and user-space file systems, and distributed storage systems.

You will develop in C and C++, tackle performance bottlenecks, advance RDMA-based data movement, and collaborate with platform and storage teams to power AI, HPC, and data-intensive workloads.

Qualifications

• Hands-on experience with FUSE and Linux file systems.
• Understanding of Linux kernel file system architecture.
• Proficient in C and C++.
• Knowledge of POSIX file system principles.
• Experience with object storage and distributed infrastructure.
• Familiarity with RDMA and high-speed networking.
• Experience near kernel-space and user-space I/O paths.
• Systems mindset for debugging infrastructure performance.
• Experience building production infrastructure platforms.

Responsibilities

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

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

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 have not worked on performance-sensitive distributed systems.
• You want a coordination-heavy role rather than deep technical ownership.
