Staff Security Engineer

DDN is seeking a highly experienced Sr. Staff Security Architect to lead the design and implementation of end-to-end security architecture across distributed storage platforms, including S3-compatible systems, POSIX-compliant file systems, and KV cache–based data services. This is an architecture role focused on working closely with engineering teams across the data path, control plane, and ecosystem/protocol domains to ensure security is deeply embedded across all layers of the platform. You will collaborate with protocol teams, storage engineers, and platform architects to define secure-by-design systems that support high-performance, multi-tenant, and AI-driven workloads. The ideal candidate brings deep expertise in distributed systems security, cryptography, identity frameworks, and storage architectures, with a strong ability to influence engineering design and guide implementation at scale.

Key Responsibilities

• Lead the design and implementation of end-to-end security architecture for distributed storage platforms, including S3-compatible systems, POSIX-compliant file systems, and KV cache–based data services.

• Partner closely with Data Path engineering teams to ensure secure, high-performance data movement across storag
