What you’ll bring

• 10+ years of hands on experience in running mission critical cloud infrastructure, combining strategic vision with hands-on execution
• Proven experience in large-scale, mission-critical cloud environments (AWS required).
• Proven track record leading platform transformation, from legacy clean-up to modern, automated infrastructure.
