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.

Required Skills & Experience

· 5+ years of hands-on experience in Linux infrastructure engineering, system automation, and OS lifecycle management.

· Primary key skills required are Ansible, Python, Packer, Kickstart, OpenSCAP

· Deep expertise with:

o Packer for automated image builds

o Kickstart for unattended OS provisioning

o OpenSCAP for security compliance and policy enforcement

o Ansible for configuration management and post-build customization

· Strong understanding of CIS/STIG hardening standards and their application in automated pipelines.

· Experience with kernel and driver management, particularly in hardware-accelerated (GPU) environments.

· Proven ability to implement GitOps workflows for infrastructure automation (e.g., Git-backed pipelines for image release and validation).

· Solid knowledge of Linux internals, bootloaders, and provisioning mechanisms in bare-metal environments.

· Exposure to Kubernetes, particularly in the context of OS-level customization and compliance.

· Strong collaboration skills across teams including security, SRE, platform, and hardware engineering.

· Bonus:

o Familiarity with image signing, SBOM generation, or secure boot workflows

o Experience working in regulated or compliance-heavy environments (e.g., FedRAMP, PCI-DSS)

o Contributions to infrastructure automation frameworks or open-source tool
