This role will focus on infrastructure automation, Kubernetes platform management, cloud reliability, and continuous improvement while working closely with application and engineering teams.

Key Responsibilities

• Design and manage AWS infrastructure using Terraform, Kubernetes, and infrastructure-as-code practices.
• Develop Terraform modules, manage remote state, and implement policy-as-code.
• Implement GitOps using tools such as Argo CD or Flux.
• Manage Kubernetes platforms, including EKS, cluster lifecycle, upgrades, scaling, and containerized workloads.
• Troubleshoot complex Kubernetes and cloud networking issues involving CNI, ingress controllers, service mesh, and load balancing.
• Build and maintain reliable CI/CD pipelines using Jenkins and related tools.
• Automate infrastructure provisioning and configuration using Ansible, Puppet, or Chef.
• Develop infrastructure-as-code and configuration-as-code across multiple environments.
• Monitor and optimize infrastructure for performance, availability, security, and cost.
• Work with monitoring and logging platforms such as Datadog, Prometheus, Grafana, or ELK.
• Manage AWS networking, including VPCs, security groups, IAM, DNS, VPN, and related services.
• Integrate third‑party tools, plugins, and internal automation scripts.
• Create technical documentation, runbooks, and architecture diagrams.
• Participate in on‑call rotations and improve incident response and reliability processes.
• Collaborate with application, engineering, security, and infrastructure teams.
• Mentor engineers and contribute to DevOps/SRE best practices.

Required Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Software Engineering, Electrical Engineering, or equivalent experience.
• 7+ years of experience in DevOps, SRE, Platform Engineering, or Infrastructure Engineering.
• 5+ years of hands‑on experience with cloud platforms, primarily AWS.
• Advanced Linux administration and troubleshooting skills, including systemd, cgroups, namespaces, OS tuning, and production hardening.
• Strong Kubernetes experience beyond fundamentals, including CNI, networking, ingress, service mesh, and cluster management.
• Hands‑on experience with AWS EKS and Docker.
• Strong expertise in Terraform and infrastructure automation.
• Strong scripting skills with Python and Bash.
• Experience with Git, Jenkins, and artifact repositories.
• Strong understanding of DNS, DHCP, VPN, LDAP, VPCs, security groups, and IAM policies.
• Experience with monitoring/logging tools such as Datadog, Prometheus, Grafana, or ELK.
• Experience working in Agile environments using JIRA and Confluence.

Nice to Have
