Senior / Staff NFS Engineer

WHY THIS ROLE IS COMPELLING

At DDN, you will work on problems that sit at the heart of modern infrastructure:

- Scaling and optimizing Network File Systems

- Building and improving distributed file systems and object storage

- Tuning performance across kernel-level and user-space I/O stacks

- Working with NVMe, SSDs, RDMA, and high-speed networking

- Integrating storage platforms into Kubernetes-native environments

- Using Python to automate, debug, test, and improve complex systems

Your work will directly influence how high-performance data platforms behave under real-world load, not just in theory.

WHAT YOU’LL DO

- Design, build, and optimize features across DDN’s NFS and storage stack

- Diagnose bottlenecks across file systems, storage media, networking, and I/O paths

- Improve performance, scalability, and resiliency in distributed storage environments

- Work across kernel-space and user-space components to solve hard systems problems

- Collaborate with engineers across storage, systems, and platform layers

- Develop tooling and automation in Python to improve observability, testing, and operations

- Help shape the next generation of infrastructure for AI and data-intensive workloads

WHAT WE’RE LOOKING FOR

- Strong hands-on experience with Network File Systems (NFS)

- Deep understanding of distributed file systems

- Experience with object storage

- Production experience with Kubernetes

- Strong Python skills

- Experience working on kernel-level and/or user-space I/O stacks

- Familiarity with NVMe, SSDs, RDMA, and high-speed networking

- A systems mindset: you know how to debug complex performance and reliability issues across layers

YOU’LL THRIVE HERE IF

- You are energized by low-level systems work

- You like solving problems most engineers avoid because they are too deep, too subtle, or too performance-sensitive

- You care about the details of how storage and networking behave under pressure

- You want your work to matter in environments where performance is mission-critical

THIS ROLE IS PROBABLY NOT FOR YOU IF

- Your background is primarily general backend, SRE, or platform engineering without deep storage/filesystem ownership

- You’ve used storage systems, but haven’t built or debugged them at a systems level

- You prefer abstraction layers over getting hands-on with performance, I/O paths, and infrastructure internals

- You want a role focused on coordination more than engineering depth
