· Lead Terraform code review processes and mentor junior team members on best practices.

3. Configuration Management — Ansible

· Author and maintain Ansible playbooks, roles, and collections for server configuration, application deployment, and compliance enforcement.

· Manage Ansible inventories across dynamic cloud environments using AWS dynamic inventory plugins.

· Integrate Ansible automation with CI/CD pipelines for repeatable and auditable deployments.

· Use Ansible Vault for secrets management and always ensure secure handling of credentials.

· Develop idempotent, well-tested automation that reduces manual toil and configuration drift.

4. Container Platform — OpenShift ROSA

· Implement GitOps workflows using ArgoCD for declarative, auditable deployments to OpenShift ROSA.

· Integrate security scanning tooling (SAST, container scanning, dependency auditing) into pipeline gates.

· Champion shift-left testing principles, ensuring infrastructure changes are validated before promotion to production.

· Maintain pipeline-as-code standards with versioned, peer-reviewed pipeline definitions.

6. Security & Compliance

· Serve as a key contributor to the team's security posture, embedding security controls throughout the infrastructure and CI/CD lifecycle.

· Implement secrets management solutions (AWS Secrets Manager) and enforce least-privilege access.

· Support vulnerability management processes by triaging findings from infrastructure and container scanning tools.

· Participate in incident response and post-mortem processes, ensuring remediation actions are tracked and resolved.

7. Observability & Reliability

· Build and maintain end-to-end observability solutions using AWS CloudWatch.

· Define and track SLOs and SLIs for critical platform services and workloads.

· Lead on-call incident response for platform-level issues, conducting RCAs and driving permanent fixes.

· Produce and maintain runbooks and architectural decision records (ADRs).
