Summary of Changes

This version positions Nutanix as a primary platform, rather than simply listing it as another virtualization technology. Candidates with genuine Nutanix administration experience (AHV, Prism, cluster operations, VM lifecycle, storage, networking, and troubleshooting) will recognize the role as a good fit, while Linux engineers without Nutanix experience will understand it is a significant requirement rather than a nice-to-have.

Role Overview
- Design, implement, and maintain enterprise Linux-based
infrastructure in both on-premises and virtualized environments.
- Administer, maintain, and optimize Nutanix hyperconverged
infrastructure (HCI), including AHV, Prism Central, and Prism
Element, to support enterprise Linux workloads.
- Collaborate with infrastructure teams to provision, configure, and
manage virtual machines, storage, networking, and cluster resources
within Nutanix environments.
- Develop and maintain automation solutions using Ansible and
scripting languages (e.g., Bash, Python).
- Standardize system configuration, patching, and deployment processes
through Infrastructure-as-Code practices.
- Administer and support Red Hat ecosystem tools, including Satellite
and Capsule.
- Integrate and manage authentication and authorization mechanisms
(e.g., OAuth, SSO, identity providers).
- Support the development of dashboards and observability solutions
using tools such as Grafana and Zabbix.
- Monitor, troubleshoot, and optimize Linux systems and Nutanix
infrastructure for performance, availability, and capacity.
- Troubleshoot complex system, virtualization, storage, networking,
and integration issues across distributed environments.
- Collaborate with cross-functional teams to improve system
reliability, scalability, security, and operational efficiency.
- Document system architecture, processes, automation workflows, and
infrastructure standards.
- Contribute to continuous improvement initiatives, including
automation maturity, platform modernization, and operational best
practices.
