• Define high-availability, disaster-recovery, backup, business-continuity, and fault-tolerance strategies.
• Drive infrastructure modernization, cloud migration, data-center transformation, and technology rationalization initiatives.
• Establish Infrastructure-as-Code and automation practices using Terraform, Ansible, CloudFormation, PowerShell, Python, or Shell scripting.
• Collaborate with DevOps and engineering teams to implement CI/CD, DevSecOps, containerization, and platform automation.
• Ensure infrastructure solutions comply with enterprise security, governance, regulatory, and compliance requirements.
• Design network and security architectures covering firewalls, load balancers, VPNs, DNS, IAM, segmentation, and secure connectivity.
• Define monitoring, observability, logging, alerting, capacity planning, and performance-management strategies.
• Identify infrastructure risks, bottlenecks, and opportunities for performance and cost optimization.
• Lead architecture reviews, proof-of-concepts, technology evaluations, and vendor assessments.
• Provide technical leadership and guidance to infrastructure, cloud, DevOps, and operations teams.
• Develop HLD/LLD documents, architecture diagrams, technical standards, implementation plans, and operational documentation.
• Work closely with business stakeholders, application architects, security teams, vendors, and senior IT leadership.
• Mentor infrastructure engineers and promote architecture and operational best practices.
• Support major production incidents and provide architectural direction for complex infrastructure problems.
