• Configure, administer, and enhance Sail Point Identity Security Cloud (ISC), including workflows, rules, connectors, and custom extensions.
• Drive automation initiatives to reduce manual access management processes and improve operational efficiency.
• Collaborate with application, infrastructure, and security teams to ensure identity requirements are embedded into application architecture and development practices.
• Monitor and optimise IAM platform performance, reliability, and integrations.
• Support identity governance, access control reviews, risk assessments, and identity-related incident investigations.
• Contribute to IAM policies, standards, and security architecture initiatives.
• Promote Identity-as-Code, Infrastructure-as-Code, and modern IAM best practices across the organisation.
