Staff/Sr Information Security Engineer

Staff or Sr Information Security Engineer Information Security — Who We Are The Information Security organization advances the overall state of security at Rubrik through critical initiatives and coordination of large security programs. Information Security builds technologies, tools, and processes to better enable teams at Rubrik to develop secure software and protect data and systems with appropriate security controls. Information Security also develops systems to monitor and respond to attacks against our systems, provides awareness education to teams on security best practices for data protection, and ensures data sharing relationships with third parties securely protect Rubrik information. What You'll Do We are seeking a Staff Security Engineer or Sr Security Engineer to serve as a technical anchor across the Information Security organization. You will own the architectural direction of our Security Data platform while simultaneously driving cross-functional security initiatives that span multiple teams and domains. This is a high-leverage, hands-on role that blends deep technical execution with organization-wide influence — shaping how Rubrik detects, responds to, and learns from threats at scale. You will be the go-to technical leader for complex, ambiguous problems that cut across team boundaries, setting standards and raising the engineering bar across SecEng. Core Responsibilities Security Data Platform — Architecture & Ownership Define and own the long-term architecture of Rubrik's Security Data infrastructure. Drive the evolution from SIEM-centric operations toward a composable Security Data Lake (Snowflake, BigQuery, Databricks), ensuring the platform is scalable, cost-efficient, and fit-for-purpose for SOC, Threat Detection, GRC, and Compliance workloads. Establish data quality standards, schema governance, and ingestion SLAs across all security telemetry pipelines. Technical Leadership Across SecEng Partner with Threat Detection, Security Operations, GRC, Product Security, and Cloud Security teams to define shared platforms, resolve architectural dependencies, and drive alignment on cross-cutting technical decisions. Own the "how we build" as much as the "what we build." Engineering Standards & Enablement Define and champion engineering best practices across SecEng: code quality, observability, incident readiness, cost management, and security-by-design. Conduct architecture reviews for major initiatives across teams. Mentor Junior engineers, accelerating their technical growth through code reviews, design feedback, and pairing. AI & Agentic Security Automation Lead the design and delivery of AI-driven security capabilities. Build and productionize AI agents that automate Tier 1/2 SecOps workflows — including alert triage, incident investigation, enrichment, and response. Evaluate and integrate LLMs and GenAI tooling to create force-multiplying capabilities across the security organization. Strategic Cross-Team Collaboration Drive alignment across Engineering, Product, IT, and Legal on security platform roadmaps, data governance, and compliance requirements. Represent InfoSec in cross-functional technical forums. Translate ambiguous business requirements into concrete technical strategies that multiple teams can execute against. Infrastructure & Platform Engineering Own the deployment and lifecycle of security tooling across cloud environments (AWS, GCP, Azure). Drive Terraform-based IaC practices, manage Kubernetes-based security sidecars and policies, and ensure platform reliability through SLOs and automated runbooks. Security Operations — Escalation & Oversight Serve as the senior technical escalation point for complex Security Operations challenges: SIEM/SOAR health, major incident response, vendor evaluations, and architectural POCs. Drive post-incident technical reviews that produce durable improvements to detection and response capabilities. Qualifications Experience: 12+ years in Security Engineering, w
