  • Manage enterprise storage architectures (SAN/NAS, backup, archival, object storage).
  • Oversee performance optimization, capacity planning, and system hardening.

DevOps & Automation

  • Lead the design and implementation of CI/CD pipelines (GitLab preferred, GitHub/Azure DevOps as plus).
  • Champion automation using IaC (Terraform, CloudFormation, Ansible).
  • Implement SRE/DevOps practices: observability, monitoring, incident response, and reliability engineering.
  • Ensure automated provisioning, configuration, and policy enforcement across environments.

Security & Governance

  • Implement cloud and infrastructure security controls: IAM, KMS, SIEM/monitoring, security baselines, and compliance frameworks.
  • Collaborate with security teams to drive zero-trust, identity governance, and audit readiness.

Leadership & Collaboration

  • Act as the technical escalation point for complex design, performance, or production issues.
  • Mentor infrastructure, cloud, DevOps, and operations engineers.
  • Work closely with application, security, and network teams to deliver integrated, end-to-end solutions.
  • Provide architectural guidance, documentation, and executive-level presentation support.

Required Skills & Experience:

Technical Competencies

  • Cloud Platforms: Strong expertise in AWS; exposure to Azure/GCP ideal.
  • Networking: VPC, routing, load balancing, firewalls, VPN, DNS, network security.
