• Work with the Software Quality Engineer to develop automation and processes to deploy, manage, scale and monitor applications in data centre and cloud environments
• Troubleshoot and resolve system and application issues, participating in on-call escalations for critical incidents
• Take ownership of end-to-end infrastructure and security solutions across the products and relevant systems
• Deploy and manage monitoring tools to track infrastructure performance, utilisation and health
• Configure and maintain CI/CD pipelines, incorporating streamlined change management and release processes
