Nice to have: - Frontend experience with Angular - Know-how in delivering software to the AWS cloud platform - Experience with Docker, Kubernetes and GitOps (e.g. Argo CD) - Experience building agentic workflows (MCP integrations, custom agent skills, AI steps in CI such as automated PR review) - Experience in regulated environments (payments, PCI-DSS, GDPR)
