Job Description

We are looking for a skilled Senior Infrastructure Automation Engineer with 10 to 15 years of experience to lead the design and implementation of a ZeroTouch Build, Upgrade, and Certification pipeline for our on-prem GPU cloud infrastructure. This role involves end-to-end stack automation from hardware provisioning to OS and Kubernetes deployment leveraging 100% GitOps workflows.

Roles and Responsibility

Architect and implement a GitOps-based pipeline for building, upgrading, and certifying Linux OS layers in the GPU cloud stack.
Design and automate Linux image builds using Packer, Kickstart, and Ansible.
Integrate CIS/STIG compliance hardening and OpenSCAP scanning into the image lifecycle and validation workflows.
Manage kernel module/driver automation, ensuring version compatibility and hardware enablement for GPU nodes.
Collaborate with SRE, platform, and security teams to standardize image build and deployment practices.
Maintain Infrastructure-as-Code repositories with GitOps compliance for traceability and reproducibility.

Job Requirements

Minimum 10 years of hands-on Linux infrastructure engineering, automation, and OS lifecycle management.
Strong expertise in Ansible, Python, Packer, Kickstart, and OpenSCAP.
Solid understanding of CIS/STIG hardening standards in automated pipelines.
Experience in kernel and driver management, especially for hardware-accelerated GPU environments.
Proven experience implementing GitOps workflows for infrastructure automation.
Deep knowledge of Linux internals, bootloaders, and bare-metal provisioning mechanisms.
Exposure to Kubernetes, particularly for OS-level customization and compliance.
Strong collaboration skills with cross-functional teams (security, SRE, platform, hardware).
Familiarity with image signing, SBOM generation, and secure boot workflows is a plus.
Experience in regulated/compliance-heavy environments (e.g., FedRAMP, PCI DSS) is beneficial.
Contributions to infrastructure automation frameworks or open-source tools are a plus.
