Lead Storage Systems Engineer

About the role : We are looking for a Principal Software Engineer with deep expertise in Kubernetes, CSI driver development, and systems programming in Golang and / or C++. In this hands-on role, you will lead the design and implementation of scalable, production-grade integrations that enable our NAS appliance to run natively within Kubernetes environments. You’ll develop a custom CSI driver, work closely with NFS / SMB protocols, and optimize storage operations within containerized workloads. Strong knowledge of Linux systems, Kubernetes internals, and cloud-native storage concepts is essential, along with a passion for building reliable infrastructure software used in enterprise-scale deployments.

Responsibilities :

• Lead the architecture, design, and Kubernetes-native deployment of our next-generation NAS appliance, enabling cloud-native workloads to access and manage data efficiently and securely.
• Design and implement a robust CSI (Container Storage Interface) driver to expose the appliance's NAS capabilities (e.G. NFS, SMB) to Kubernetes environments, supporting persistent volumes, dynamic provisioning, snapshots, and related storage lifecycle operations.
• Collaborate closely with product, platform, and architecture teams to define the technical strategy for container storage integration, ensuring that the system supports multi-tenancy, scalability, and high availability.
• Work extensively with storage protocols such as NFSv3 / v4, SMB, and CIFS, integrating them into the Kubernetes ecosystem in a performant and secure manner.
• Deeply interact with the Linux subsystem, including the VFS layer, mount namespaces, filesystems, and kernel-level tuning to ensure performance and stability of storage mounts within containers.
• Develop Kubernetes-compliant packaging and lifecycle automation using Helm, Operators, and Custom Resource Definitions (CRDs) to facilitate deployment and upgrades of the NAS appliance in production clusters.
• Troubleshoot complex issues across distributed systems, networking, and persistent storage layers — including root cause analysis across the stack : containers, orchestration, filesystem, and kernel.
• Act as a subject matter expert (SME) for Kubernetes storage integrations and provide technical leadership in sprint planning, code reviews, and architectural decision-making.
• Mentor junior engineers, foster knowledge sharing, and help build a high-performance, high-collaboration engineering culture.

Required Skills :

o Custom Resource Definitions (CRDs)

o Controllers and Operators

o StatefulSets, DaemonSets, and volume lifecycle management

o Scheduling implications of storage and node affinity

o NFS (v3 / v4) — mount options, lock handling, network tuning

o SMB / CIFS — integration, authentication, performance tuning

o Object storage (S3, MinIO, Ceph, etc.) is a plus
