We are looking for a Senior Network & Kubernetes Migration Specialist (6-9 years experience) to lead and execute large-scale AWS network and container platform migration initiatives. This role requires deep expertise in AWS networking, enterprise hybrid connectivity, and strong hands-on experience with Amazon EKS from both infrastructure and application perspectives.

1. AWS Network Architecture & Migration
- Lead end-to-end migration of on-premises and hybrid network environments to AWS.
- Design complex AWS networking architectures including multi-account VPC strategy, subnet segmentation, routing, NAT, IGW, and load balancing.
- Architect and implement AWS Transit Gateway (hub-and-spoke, inter-region, multi-account connectivity).
- Design hybrid connectivity using AWS Direct Connect, Site-to-Site VPN, and BGP routing.
- Perform network segmentation aligned with zero-trust principles.
- Lead migration risk assessment, rollback planning, and phased cutover strategies.
- Optimize network cost, latency, and high availability post migration.

2. Security & Governance
- Define and enforce enterprise-grade security policies using Security Groups, NACLs, AWS Network Firewall, and third-party firewalls.
- Implement inspection VPC and centralized egress architectures.
- Collaborate with security teams on compliance and regulatory requirements.
- Implement guardrails using SCPs and IAM boundaries.

3. Amazon EKS - Infrastructure Perspective
- Design and operate production-grade Amazon EKS clusters.
- Architect multi-cluster and multi-environment EKS strategies.
- Design cluster networking (CNI, IP management, pod density planning).
- Optimize VPC CNI, prefix delegation, and subnet sizing.
- Implement cluster autoscaling using Karpenter and Cluster Autoscaler.
- Manage node lifecycle, taints/tolerations, and capacity planning.
- Implement IRSA (IAM Roles for Service Accounts).
- Upgrade and patch Kubernetes clusters with minimal downtime.

4. Amazon EKS - Application Perspective
- Support application teams in migrating workloads to Kubernetes.
- Design ingress strategies (ALB / NGINX Ingress).
- Optimize application networking (Services, Network Policies, DNS).
- Troubleshoot pod-to-pod and cross-cluster communication issues.
- Implement scalability and resilience patterns (HPA, PDB, readiness/liveness probes).

5. Platform Engineering & Automation
- Automate infrastructure provisioning using Terraform (modular approach).
- Implement GitOps workflows using Argo CD.
- Build CI/CD pipelines using GitHub Actions or Jenkins.
- Define policy-as-code using Kyverno.
- Develop automation scripts using Python or Go.

Required Skills &
Qualifications
- 6-9 years of experience in AWS infrastructure, networking, and cloud-migrations.
- Strong expertise in AWS VPC, Transit Gateway, Direct Connect, and VPN.
- Deep understanding of enterprise networking concepts (BGP, routing, firewalls, segmentation).
- Strong production experience with Amazon EKS (cluster design, scaling, networking optimization).
- Hands-on experience with Kubernetes networking internals.
- Strong Terraform expertise (module design, remote state management).
- Experience implementing GitOps and CI/CD pipelines.
- Scripting experience with Python or Go.
- Strong troubleshooting and stakeholder communication skills.
