Senior Cloud Security Engineer

Defines the architecture and technical direction for cloud security, improving posture and tooling at org scale — designing for automation, extensibility, and cross-functional adoption while shaping the team's strategic roadmap. Core Responsibilities • Defines and owns the technical architecture for CSPM tooling, automation platforms, and integration frameworks — ensuring they scale reliably across thousands of cloud accounts and multiple business units. • Designs system-level patterns (event-driven pipelines, API contracts, data models) that other engineers build on — establishing the foundational approach for how security findings flow from detection through prioritization to remediation. • Drives architectural decisions on platform extensibility, service boundaries, and data ownership — balancing near-term delivery against long-term maintainability as the program grows. • Architects auto-remediation and shift-left enforcement systems that operate at org scale — designing for fault tolerance, auditability, and graceful degradation when upstream systems change. • Evaluates and selects tooling, frameworks, and integration patterns that the broader team adopts — owning the technical standards for how CSPM systems connect to enterprise infrastructure (CI/CD, CMDB, ITSM, identity providers). • Partners with engineering leadership across Platform, DevOps, SRE, and application security teams to align on shared interfaces, data contracts, and remediation workflows that reduce friction at organizational boundaries. • Leads technical design reviews and mentors engineers on the team — raising the bar on code quality, system thinking, and operational readiness. • Shapes the technical roadmap for AI-assisted security capabilities — evaluating where machine learning and LLM-based automation can meaningfully reduce risk or operational burden, and architecting the systems to deliver them. Qualifications • Minimum of five years related work experience required, with two years experience in cloud security preferred. • Undergraduate degree in a related field or the equivalent combination of training and experience. • Proficiency in Python, Go or TypeScript - production-grade, not just scripting • Strong background in distributed systems concepts: event-driven architectures, async processing, API design, observability • Hands-on experience across at least one of: AWS, GCP, Azure — at the level of org-wide account structures, landing zones, and cross-account security patterns and IAM at scale. • Track record of influencing technical direction beyond your immediate team Special Factors Sponsorship Vanguard is not offering visa sponsorship for this position.
