Position Overview

We are seeking an experienced Linux Engineer to manage and optimize our Linux-based infrastructure across cloud and on-prem environments. The ideal candidate will have strong expertise in Linux system administration, automation, and performance tuning, with exposure to Kubernetes, CI/CD pipelines, and hybrid cloud deployments.

You’ll work closely with infrastructure, security, and development teams to maintain secure, compliant, and highly available systems supporting business-critical workloads.

Key Responsibilities

Linux Administration & Operations

Administer and support Linux servers (Ubuntu, CentOS, RHEL, or Debian) across production and development environments. Perform system configuration, patching, and performance tuning for high availability and reliability. Manage user accounts, permissions, file systems, and kernel parameters. Troubleshoot hardware, network, and OS-level issues to ensure system stability. Maintain system monitoring, logging, and alerting frameworks (Prometheus, Grafana, ELK, etc.).

Automation & Infrastructure Management

Develop and maintain automation scripts in Bash, Python, or Ansible. Implement Infrastructure as Code (IaC) using Terraform or Ansible. Automate provisioning, configuration, and deployment of Linux servers and applications. Support CI/CD pipelines and integrate infrastructure automation with DevOps workflows.

Cloud & Container Platforms

Manage Linux workloads on cloud environments (AWS, Azure, GCP). Deploy and maintain applications on Kubernetes or Docker environments. Configure storage, networking, and compute resources for hybrid or multi-cloud deployments. Ensure cloud-native Linux instances meet performance and compliance standards.

Security & Compliance

Implement hardening, access controls, encryption, and vulnerability patching in line with PCI DSS, ISO 27001, or internal security policies. Administer firewall configurations, SELinux/AppArmor, and audit logging. Collaborate with InfoSec teams on security assessments and audit readiness.

Monitoring, Backup & DR

Configure system monitoring and alerting for capacity, performance, and incident management. Ensure backup, recovery, and disaster recovery strategies are tested and documented. Support incident response and root cause analysis (RCA) for infrastructure issues.

Required Skills & Qualifications

Bachelor’s degree in computer science, Information Technology, or related field. 5–8 years of experience managing Linux systems in production environments. Strong hands-on experience with: System administration, performance tuning, and kernel-level configuration. Automation tools (Ansible, Terraform, or SaltStack). Scripting (Bash, Python, or Go). Cloud environments (AWS, Azure, or GCP). Containers (Docker, Kubernetes). Proficiency in networking fundamentals (DNS, DHCP, routing, firewalls). Familiarity with monitoring tools (Prometheus, Grafana, ELK, Zabbix). Strong troubleshooting, documentation, and collaboration skills.

Preferred Qualifications

Certifications such as RHCE, LFCE, AWS SysOps Administrator, or CKA. Experience with GitOps, Helm, or ArgoCD. Exposure to Zero Trust, identity, or compliance frameworks. Experience in Fintech / regulated environments is a plus.
