The role will focus on improving and scaling an established AWS platform, with particular responsibility for reviewing and evolving the existing Landing Zone as AWS adoption grows across the organisation.

• Review existing cloud foundations and identify opportunities for improvement.
• Build and automate cloud infrastructure using Terraform and Python.
• Improve self-service capabilities for engineering teams consuming AWS.
• Strengthen cloud governance, security and operational standards.
• Take ownership of complex technical problems and key platform engineering decisions.
• Work closely with engineering, security and architecture teams across the organisation.

Experience Required

• Strong experience designing, building or significantly improving AWS Landing Zones.
• Strong Terraform experience.
• Python scripting and automation experience.
• Strong understanding of enterprise multi-account AWS environments.
• Good understanding of cloud security and governance.
• Experience operating within large, complex enterprise environments.
