Design, develop, and maintain reusable Terraform modules and infrastructure-as-code patterns for AWS services.

Build standardized AWS infrastructure blueprints for common workload archetypes, including compute, networking, security, storage, messaging, and observability components.

Implement secure and scalable AWS environments using services such as VPC, IAM, EC2, EKS, ECS, Lambda, S3, RDS, DynamoDB, Cloud Watch, KMS, Secrets Manager, and related platform services.

Integrate Terraform automation with CI/CD pipelines, source control, policy-as-code, security scanning, and enterprise change management workflows.

Enable self-service infrastructure provisioning through reusable modules, templates, APIs, and platform automation workflows.

Develop and maintain Terraform state management, module versioning, release practices, and environment promotion standards.

Implement cloud security guardrails including IAM least privilege, encryption, network segmentation, logging, monitoring, and compliance controls.

Collaborate with platform, cloud, application, security, and operations teams to align solutions with architecture standards and enterprise technology governance.

Troubleshoot complex AWS and Terraform deployment issues across development, test, and production environments.

Establish best practices for infrastructure as code, cloud provisioning, tagging, cost optimization, resiliency, and operational readiness.
