About the role
- 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
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 storage tiers, including encryption, integrity validation, and secure I/O handling.
- Lead threat modeling, security reviews, and Secure Software Development Lifecycle (SSDLC) practices across the platform.
- Design multi-tenant isolation mechanisms across namespaces, policies, encryption boundaries, and resource quotas, enforcing least privilege and segregation of duties.
- Collaborate with Control Plane teams to define secure APIs, authentication and authorization workflows, policy enforcement, and tenant lifecycle management.
- Drive observability and monitoring strategies to detect anomalous behavior, abnormal access patterns, and potential data exfiltration across the platform.
- Provide technical leadership and mentorship across cross-functional engineering teams, guiding secure design and implementation practices.
Requirements
- Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
- 12+ years of experience in security architecture, infrastructure security, or distributed systems.
- Proven experience designing security for large-scale distributed systems or storage platforms.
- Strong understanding of data path vs. control plane architectures and their security implications.
- Deep expertise in encryption technologies, key management systems, and cryptographic frameworks.
- Experience integrating with external KMS solutions using KMIP or similar protocols.
- Strong knowledge of identity and access management (IAM), including RBAC, ABAC, SSO, MFA, and federation.
- Experience working with enterprise identity providers such as LDAP, Active Directory, and OIDC.
- Experience designing multi-tenant systems with strong isolation and policy enforcement.
- Knowledge of logging, auditing, and SIEM integration for security monitoring and compliance.
Skills
- Experience working with S3, POSIX/NFS, or similar storage protocols from a security architecture perspective.
- Familiarity with KV cache systems, memory tiering, or AI/ML data infrastructure security considerations.
- Hands-on experience with BYOK models and tenant-scoped key management.
- Experience implementing ABAC using metadata, tags, and classification attributes.
- Experience with secure deletion techniques, including cryptographic erasure.
- Knowledge of compliance frameworks such as SOC 2, ISO 27001, NIST, or FedRAMP.
- Experience designing security for high-performance, low-latency distributed systems.
- Familiarity with anomaly detection, security analytics, and alerting systems.
- Defining and driving security architecture across data path, control plane, and protocol layers of distributed storage systems
- Partnering with engineering teams to embed security into S3, POSIX, and KV cache data services
- Strengthening tenant isolation, auditability, and compliance across the platform
- Ensuring secure integration across ecosystem components and external services
