• Excellent written and verbal communication in English, including with executive and non- technical audiences
• Strong incident leadership credentials, being able to run a major incident calmly and to lead the systemic follow-up afterwards
• Expert or Professional-level certification in AWS (for example AWS Certified Solutions Architect – Professional, or AWS Certified DevOps Engineer – Professional) and Expert-level certification in Azure (for example Microsoft Certified: Azure Solutions Architect Expert, or Azure DevOps Engineer Expert). Both clouds required
• Substantial experience leading cloud operations, SRE or platform engineering organizations at enterprise scale, including experience leading managers and multi- region teams
