Principal Security Engineer

Identify high-leverage security risks and trust seams affecting critical services, and translate them into clear, prioritized mitigation plans. Design enforceable security architectures and isolation patterns across identity, tenant/security boundaries, and adjacent infrastructure layers. Define security policies and guardrails that can be deployed safely at scale (phased rollout, validation gates, rollback strategy). Partner with engineering teams across organizations to land durable controls in production, reducing reliance on exceptions and manual processes. Establish proof mechanisms (telemetry/validation) to measure coverage, detect drift, and verify controls are continuously effective. Produce crisp technical artifacts (reference architectures, decision docs, implementation guidance) that unblock execution and scale adoption. Doctorate in Statistics, Mathematics, Computer Science, or related field AND 3+ years experience in software development lifecycle, large-scale computing, threat modeling, cyber security, anomaly detection, Security Operations Center (SOC) detection, threat analytics, security incident and event management (SIEM), information technology (IT), or operations incident response OR Master's Degree in Statistics, Mathematics, Computer Science, or related field AND 4+ years experience in software development lifecycle, large-scale computing, threat modeling, cyber security, anomaly detection, Security Operations Center (SOC) detection, threat analytics, security incident and event management (SIEM), information technology (IT), or operations incident response These requirements include, but are not limited to the following specialized security screenings: 8+ years in security architecture and/or systems engineering for large-scale cloud or distributed systems. Strong technical depth in identity and access management (authN/authZ, RBAC/ABAC concepts, least privilege, credential/secrets lifecycle). Demonstrated experience designing security controls that are enforceable (not just reviews/standards) and driving them into production with partner teams. Strong written and verbal communication skills, including ability to influence senior technical stakeholders and drive decisions. Depth in one or more infrastructure verticals (e.g., networking, compute, storage, engineering systems, supply chain/security of build and release). Experience building or operating policy/guardrail platforms (stable contracts/APIs, orchestration, deployment validation, drift detection). Experience in incident-driven security improvements (translating real attack patterns into durable controls). Familiarity with compliance-constrained or regulated cloud environments (e.g., sovereign/regional deployments) and how to maintain security posture under constraints.
