• Contribute to technical discovery (spikes) and document findings
• Support CI/CD, IaC, and cloud environments (GitHub Actions, Terraform, AWS CDK, CloudFormation)
• Monitor and support live services, including incident analysis and preventative fixes
• Ensure solutions meet security, accessibility, performance, and data‑protection standards
