• Own and mature backup and cyber recovery practices, including hands‑on use of Rubrik or a comparable enterprise data protection platform for backup policy management, immutability, restore validation, coordinating recovery procedures, reporting, evidence capture and operational support for critical workloads.
• Partner with Cybersecurity on ransomware and destructive cyber event readiness, including clean recovery, backup integrity validation, isolated recovery environments, cyber recovery vault operations and restoration of critical services.
• Ensure resilience and recovery requirements are embedded into architecture, cloud migration, vendor onboarding, operational readiness, change delivery and service governance.

• Lead, manage and coach group of engineers working across reliability, observability, production support, technology resilience and recovery practices.
• Build a clear operating model for SRE and technology resilience ownership across application teams, infrastructure teams, cloud/platform teams, cybersecurity, operational resilience and third‑party providers.
• Define reliability and resilience reporting for senior leaders, including service health, SLO performance, incident trends, MTTR, alert quality, recovery readiness, open…
