• Coordinate and run evidence collection cycles in support of internal reviews, external assessments, and audit activities
• Serve as the primary compliance point of contact for internal auditors, external assessors, and compliance stakeholders
• Partner closely with platform, cloud, and security engineers to validate that documented control narratives accurately reflect implemented infrastructure and operational practices
• Review architecture diagrams, infrastructure-as-code, technical diagrams, and engineering documentation to ensure compliance materials remain accurate and defensible
• Help ensure consistency, traceability, and quality across all compliance documentation and supporting artifacts
• Identify documentation gaps, policy inconsistencies, or control narrative issues early and drive them to resolution
• Support the maturation of repeatable compliance processes that strengthen audit readiness over time

Skills
