Senior Platform/DevOps Engineer

About the Role

We are seeking an experienced, collaborative, and detail-oriented Senior Platform/DevOps Engineer to join our growing Edge team. You will be a subject matter expert in Microsoft Azure and Kubernetes, responsible for the design, automation, optimization, and operation of our hybrid Azure Local and Kubernetes-based deployments on bare metal infrastructure. You will support our Galleon mobile data centers and AEP integration, ensuring the reliability and performance of our distributed computing platform. This is a critical role where you will leverage technical expertise in Azure, bare-metal provisioning, and Linux to build and manage resilient, secure, and scalable hybrid environments across diverse edge locations.

What You'll Do (Key Responsibilities)

• Platform Architecture & Management
• Architect, design, deploy, and manage highly available Azure Local environments on bare metal servers across our edge data centers.
• Architect, design, deploy, configure, and manage Kubernetes clusters on-prem (Galleon data centers) and cloud (Azure) environments.
• Utilize Azure Arc to centrally manage and monitor distributed Azure Local instances, ensuring consistent governance and security.
• Administer, maintain, and monitor the health, performance, and capacity of Kubernetes clusters and underlying infrastructure.
• Implement and manage Kubernetes networking solutions (CNI plugins, Ingress controllers) and storage solutions (PV/PVC, Storage Classes, CSI drivers).
• Automation & Infrastructure as Code (IaC)
• Lead the automation of Azure Local deployment and configuration, including network, storage, and security setup.
• Drive Infrastructure-as-Code (IaC) initiatives using tools like Terraform, Ansible, Helm, and potentially Kubernetes Operators to promote automation, repeatability, and reliability.
• Develop and maintain automation scripts and IaC templates for repeatable and scalable deployments.
• Automate cluster operations, deployment pipelines (CI/CD integration), and infrastructure provisioning.
• Security, Optimization & Operations
• Secure Azure Local deployments using best practices and technologies such as Azure Policy, Azure Key Vault, and network security groups.
• Implement and enforce Kubernetes security best practices (RBAC, Network Policies, Secrets Management, Security Contexts, Image Scanning).
• Troubleshoot and resolve complex issues related to Azure Local, bare metal infrastructure, networking, Kubernetes platform, and containerized services.
• Optimize Kubernetes clusters for performance, scalability, and resource utilization, particularly in edge environments.
• Contribute to the operational excellence of the platform, including participating in on-call rotations, incident management, and building self-healing capabilities.
