• CI/CD Integration: Work closely with DevOps and software engineering teams to support continuous integration and deployment pipelines (Jenkins, GitLab CI, GitHub Actions).

Required Qualifications

• Experience: 4+ years of hands-on experience in Linux system administration and IT infrastructure engineering.
• OS Expertise: Deep understanding of Linux internals, file systems (LVM, NFS, EXT4, XFS), kernel tuning, and package management.
• Scripting Skills: Strong proficiency in writing automation scripts in Bash, Python, or Go.
• Networking Knowledge: Solid grasp of core networking protocols and concepts (TCP/IP, DNS, DHCP, SSH, VPNs, Load Balancing, and routing).
• Hardware/Storage: Experience managing bare-metal servers, SAN/NAS storage, and RAID configurations.

Preferred Qualifications (Nice to Have)

• Industry certifications such as RHCE (Red Hat Certified Engineer), AWS Certified SysOps Administrator, or CKA (Certified Kubernetes Administrator).
• Experience managing GPU-accelerated infrastructure or AI/ML computing platforms.
• Familiarity with Bare Metal as a Service (BMaaS) platforms.
• Experience migrating legacy on-premise infrastructure to public cloud platforms.
