• Critical Incident Leadership: Lead investigation and resolution of critical incidents, driving coordination across internal teams, vendors, and customer stakeholders.
• End-to-End Technical Ownership: Make technical decisions and take end-to-end ownership of infrastructure issues, driving resolution without reliance on further escalation.
• Project Delivery: Lead technical delivery of infrastructure projects, including scoping, estimation, design, and implementation.
• Root Cause Analysis: Perform root cause analysis and develop long-term remediation strategies to prevent recurrence of infrastructure issues.
• Change Validation: Validate and approve infrastructure changes, designs, and remediation strategies to ensure quality and compliance.
