Technical leadership

• Review solution designs, perform architectural assurance and guide teams through implementation challenges

Security and compliance

• Implement security controls including IAM policies, encryption, network segmentation, monitoring and threat detection
• Ensure compliance with GDPR, ISO27001 and PCI DSS through AWS-native tools and architectural controls

Infrastructure as Code

• Lead adoption of IaC using Terraform, CloudFormation or CDK
• Standardise reusable templates and modules for consistent, repeatable deployments across environments

Performance and cost optimisation

• Monitor workloads with CloudWatch, Trusted Advisor and Cost Explorer
• Optimise for performance, reliability, cost efficiency and operational excellence

Cloud migration and modernisation

• Define migration strategies including rehosting, refactoring, replatforming and containerisation
• Design modern architectures involving microservices, serverless, APIs and event-driven patterns

Stakeholder engagement

• Act as the technical counterpart to product owners, business stakeholders and delivery managers
• Explain complex cloud concepts in clear, non-technical language

Troubleshooting and escalation

• Provide advanced support for complex issues across application, infrastructure and integration layers
• Lead root cause analysis for high-priority incidents involving AWS workloads
