We're hiring on behalf of a client operating in high-security, mission-critical environments where uptime, resilience, and security are non-negotiable.

• Take full ownership of AWS RDS (PostgreSQL)
• Build and maintain robust data/reporting pipelines
• Operate and scale EKS (Kubernetes) clusters
• Implement and manage GitOps workflows (ArgoCD) and CI/CD pipelines end-to-end
• Drive security best practices across AWS
• Perform deep troubleshooting across the stack
• Optimise container builds and runtime performance

Experience

• Has strong, hands-on AWS experience in live, production environments
• Is comfortable owning systems end-to-end, from design to incident resolution
• Has worked in high-availability, high-security, or critical systems environments
• Can debug complex issues across infrastructure, networking, and application layers
• Brings an engineering mindset
