Job Description :

Senior Infrastructure Automation Engineer (Zero-Touch GPU Cloud Stack – Linux Image Lifecycle)

We are seeking a Senior Infrastructure Automation Engineer with 10+ years of experience to lead the design and implementation of a Zero-Touch Build, Upgrade, and Certification pipeline for our on-prem GPU cloud infrastructure. This role focuses on automating the full stack—from hardware provisioning through OS and Kubernetes deployment—leveraging 100% GitOps workflows. The candidate will bring deep expertise in Linux systems automation, image management, and compliance hardening, with a strong foundation in infrastructure engineering.

Key Responsibilities

• Architect and implement a fully automated, GitOps-based pipeline for building, upgrading, and certifying the Linux operating system layer in the GPU cloud stack (hardware → OS → Kubernetes → platform).
• Design and automate Linux image builds using Packer, Kickstart, and Ansible.
• Integrate CIS / STIG compliance hardening and OpenSCAP scanning directly into the image lifecycle and validation workflows.
• Own and manage kernel module / driver automation, ensuring version compatibility and hardware enablement for GPU nodes.
• Collaborate with platform, SRE, and security teams to standardize image build and deployment practices across the stack.
• Maintain GitOps-compliant infrastructure-as-code repositories, ensuring traceability and reproducibility of all automation logic.
• Build self-service capabilities and frameworks for zero-touch provisioning, image certification, and drift detection.
• Mentor junior engineers and contribute to strategic automation roadmap initiatives.
