Senior Technical Lead - Cloud and Infrastructure Engineering

Sr Technical Lead-Cloud & Infra Engg Area(s) of responsibility . Key Responsibilities 1. Ansible Automation & Deployment Design, develop, and maintain Ansible playbooks, roles, and collections for provisioning, configuration management, OS patching, and compliance enforcement across enterprise Linux environments. Build and manage Infrastructure-as-Code (IaC) pipelines integrating Ansible with CI/CD platforms (Jenkins, GitLab CI/CD) to deliver repeatable, auditable deployments. Automate routine Linux operational tasks — user management, package installations, security hardening, disk expansion, log rotation — to reduce manual effort and eliminate configuration drift. Develop and maintain Ansible Automation Platform (AAP/AWX) workflows, including dynamic inventories, credentials management, and job scheduling. Integrate Ansible automation with AWS APIs and services (EC2, SSM, S3) to support cloud-native Linux provisioning and lifecycle management. Version-control all automation artifacts in Git; conduct peer reviews and maintain documentation standards for all playbooks and roles. 2. Linux System Administration & Maintenance Administer enterprise Linux distributions (RHEL 7/8/9, CentOS, Oracle Linux, Amazon Linux 2/2023) across on-premises, hybrid, and AWS environments. Manage core Linux subsystems: kernel parameters, LVM/storage management, NFS/SMB mounts, network configuration (bonding, VLANs), firewalld/iptables, PAM, SSH hardening, and systemd services. Perform security hardening using CIS/STIG benchmarks; manage SELinux policies, sudoers configuration, and PKI/certificate lifecycle. Operate and optimize AWS Linux infrastructure: EC2 instance management, EBS volume management, AMI lifecycle, Auto Scaling Groups, and VPC networking for Linux workloads. Utilize AWS Systems Manager (SSM) for patch management, parameter store management, session management, and automated runbook execution on Linux fleets. Plan and execute scheduled maintenance: OS patching cycles, kernel upgrades, capacity planning, and infrastructure lifecycle activities in compliance with change management processes. Implement and validate high-availability and disaster recovery configurations including clustering (Pacemaker/Corosync), load balancing, and snapshot-based backup strategies Experience Level Senior Level
