Experience conducting security design or architecture reviews for enterprise applications, SaaS platforms, integrations, or internally developed systems. Strong understanding of authentication, authorization, SSO, federation, SCIM, API security, token handling, secrets management, and least privilege design Experience assessing data flows, third-party integrations, trust boundaries, logging and monitoring, and security controls across interconnected systems. Ability to evaluate risk in modern enterprise environments, including automation platforms, AI-adjacent workflows, and emerging integration patterns such as MCP. Strong written and verbal communication skills, including the ability to translate technical risk into clear requirements and actionable guidance. Experience driving security outcomes through engineering judgment, influence, and scalable process improvement. Familiarity with cloud platforms, enterprise identity systems, and core control domains such as audit logging, encryption, access control, data retention, and incident response. Outcomes OUTCOME 1: Strengthen security practices across enterprise application and integration reviews by identifying key risks early, improving requirement quality, and helping teams address security issues earlier in the lifecycle. OUTCOME 2: Strengthen Enterprise Security’s capability to assess and guide AI-adjacent security, MCP and integration security, and cross-system data flow risk, while improving the consistency and scale of security reviews. OUTCOME 3: Demonstrate the ability to build automation and agent capabilities that help secure systems from the start by allowing IT workflows, internal bots, and automation platforms to call Enterprise Security guidance directly for risk triage, control validation, and escalation decisions. This should reduce dependency on manual review and embed security guidance earlier in the system lifecycle.
