The role
In this role, you’ll take ownership of our AWS landing zones and shared platform services, designing secure, scalable, multi-account environments that balance autonomy for engineering teams with strong governance and compliance. You’ll deliver robust, automated foundations using Infrastructure as Code, enabling consistent and repeatable cloud adoption across the organisation.
This is a highly collaborative role, working closely with application engineers, architecture, security, and other platform teams to support the design and delivery of cloud-based workloads. You’ll provide architectural guidance, define best practices, and ensure reliability, security, and operational excellence are embedded throughout the stack.
