System Administration & Automation

• Administer and harden Linux systems for security, compliance, and high performance.
• Automate environment provisioning and configuration using Ansible, Terraform, or Python/Bash scripting.
• Implement infrastructure as code (IaC) for reproducible and consistent deployments.
• Manage monitoring, alerting, and logging with tools like Prometheus, Grafana, Loki, and ELK.

Security, Compliance & Reliability

• Maintain PCI DSS–compliant infrastructure, including segmentation, logging, and access control.
• Integrate HashiCorp Vault for secure secret and key management.
• Apply system hardening, patching, and vulnerability management best practices.
• Develop and test backup, DR, and failover strategies for production services.

Collaboration & Continuous Improvement

• Work closely with Engineering and DevOps teams to optimize application deployment, scaling, and performance.
• Collaborate with Operations to ensure uptime SLAs and continuous monitoring of live environments.
• Participate in architecture reviews and propose improvements in reliability, cost, and security.
• Document deployment processes, configurations, and operational playbooks.

Required Skills & Qualifications

• Bachelor’s degree in computer science, IT, or a related field.
• 5–8 years of experience in application deployment, infrastructure management, or DevOps engineering.
• Expert-level proficiency in Linux system administration and scripting (Bash, Python, Go).
• Strong experience with containerized environments (Docker, Podman, Kubernetes).
• Hands-on configuration and tuning experience with:
