Senior Network & Kubernetes Migration Specialist

We are seeking an experienced professional to lead the strategic evolution of our cloud infrastructure, focusing on the secure transition to containerized environments. This pivotal role is responsible for architecting and executing complex network migrations within AWS, ensuring high availability and robust security postures for Kubernetes workloads. The ideal candidate will bridge the gap between traditional networking principles and modern cloud-native technologies, driving efficiency and reliability across our distributed systems while managing a team of engineers in a high-stakes, fast-paced IT services environment.

Responsibilities

• Design and implement secure network architectures for Amazon EKS clusters, including the configuration of security groups, Network Access Control Lists (NACLs), and AWS Network Firewall policies.
• Manage application load balancing strategies using ALB and NGINX Ingress controllers, ensuring optimal traffic distribution and high availability.
• Define and enforce network segmentation and isolation policies through Kubernetes Network Policies and Horizontal Pod Autoscaling (HPA) configurations.
• Develop and maintain automated deployment pipelines utilizing GitHub Actions and Jenkins, integrating policy enforcement tools like Kyverno to ensure compliance.
• Engineer scalable connectivity solutions leveraging AWS VPC, Transit Gateway, Direct Connect, and Site-to-Site VPNs to support hybrid cloud environments.
• Optimize routing protocols, NAT gateways, and load balancing mechanisms to enhance network performance and reduce latency.
• Write and maintain custom automation scripts in Python or Go to streamline operational tasks and enhance infrastructure management capabilities.
• Oversee the end-to-end migration of legacy applications to Kubernetes, ensuring minimal downtime and seamless integration with existing systems.
