Job description

Key Responsibilities:

Cloud & Infrastructure Architecture

• Design secure, scalable, and highly available multi-cloud architectures (AWS required; Azure/GCP an advantage)
• Define and govern architecture standards, frameworks, and best practices across cloud, network, compute, storage, and security domains
• Lead cloud adoption, migration, modernization, and hybrid integration initiatives
• Architect containerized and serverless workloads (Docker, Kubernetes/EKS, Lambda, Step Functions)

Network Infrastructure

• Design and optimize enterprise and cloud network architectures: VPC, Transit Gateways, Direct Connect, VPN, Load Balancers, WAF, routing, and segmentation.
• Work with on-prem LAN/WAN, firewalls, DNS/DHCP/IPAM, and network security.
• Collaborate with network engineering teams to ensure seamless cloud-to-on-prem integration.

Server, Virtualization &Storage

• Lead the design, deployment, and operations of compute platforms (VMware, Hyper-V, EC2, bare-metal systems).
• 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.
• Compute/Storage: VMware/virtualization, enterprise storage, backup/recovery, OS hardening.
• Container & Orchestration: Docker, Kubernetes, EKS.
• DevOps: CI/CD (GitLab preferred), GitOps, release automation.
• IaC: Terraform (preferred), CloudFormation, Ansible.
• Programming/Scripting: Python, Bash, or PowerShell.
• Monitoring/Observability: CloudWatch, CloudTrail, VPC Flow Logs, OpenTelemetry ecosystem.
• Security: IAM, KMS, encryption, cloud network security.

Certifications

• AWS Solutions Architect (Professional required; Associate acceptable if near completion)
• Additional certifications in Azure, GCP, Kubernetes, or Security are advantageous.
