The systems engineer will be responsible\nfor supporting the customer’s enterprise environment.\nSummary of Changes\nThis 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.\nRole Overview\n- Design, implement, and maintain enterprise Linux-based\ninfrastructure in both on-premises and virtualized environments.\n- Administer, maintain, and optimize Nutanix hyperconverged\ninfrastructure (HCI), including AHV, Prism Central, and Prism\nElement, to support enterprise Linux workloads.\n- Collaborate with infrastructure teams to provision, configure, and\nmanage virtual machines, storage, networking, and cluster resources\nwithin Nutanix environments.\n- Develop and maintain automation solutions using Ansible and\nscripting languages (e.g., Bash, Python).\n- Standardize system configuration, patching, and deployment processes\nthrough Infrastructure-as-Code practices.\n- Administer and support Red Hat ecosystem tools, including Satellite\nand Capsule.\n- Integrate and manage authentication and authorization mechanisms\n(e.g., OAuth, SSO, identity providers).\n- Support the development of dashboards and observability solutions\nusing tools such as Grafana and Zabbix.\n- Monitor, troubleshoot, and optimize Linux systems and Nutanix\ninfrastructure for performance, availability, and capacity.\n- Troubleshoot complex system, virtualization, storage, networking,\nand integration issues across distributed environments.\n- Collaborate with cross-functional teams to improve system\nreliability, scalability, security, and operational efficiency.\n- Document system architecture, processes, automation workflows, and\ninfrastructure standards.\n- Contribute to continuous improvement initiatives, including\nautomation maturity, platform modernization, and operational best\npractices.\nKey Responsibilities\nN/A\nRequirements:\n- 5+ years of experience administering and engineering Linux systems\nin enterprise environments, including experience supporting\nenterprise virtualization platforms such as Nutanix.\n- Required Skills\n- Solid understanding of Linux system administration fundamentals\n(networking, storage, security, and OS internals).\n- Strong expertise in configuration management and automation using\nAnsible.\n- Proficiency in scripting (Bash, Python, or similar) for automation\nand tooling.\n- Experience managing Red Hat-based environments (RHEL, Satellite,\nCapsule, or similar tools).\n- Hands-on experience administering Nutanix HCI environments,\nincluding AHV, Prism Central, Prism Element, virtual machine\nlifecycle management, storage, networking, and cluster operations.\n- Experience deploying, managing, and troubleshooting Linux virtual\nmachines in Nutanix environments.\n- Understanding of virtualization, hypervisor technologies, storage,\nand networking concepts.\n- Experience troubleshooting complex infrastructure, virtualization,\nand performance issues.\n- Experience implementing security best practices in Linux\nenvironments.\n- Experience with monitoring and alerting systems.\n- Strong problem-solving skills and ability to work independently.\n- Active TS/SCI clearance required and eligibility to obtain a CI\nPolygraph.\nPreferred:\n- Experience with Nutanix advanced capabilities such as Files,\nObjects, Flow, Calm, or Disaster Recovery.\n- Experience with Nutanix automation using APIs, PowerShell, or\nInfrastructure-as-Code tools.\n- Experience with load balancing devices such as HAProxy or F5.\n- Familiarity with authentication and authorization concepts (e.g.,\nOAuth, LDAP, SSO).\n- Experience with observability and dashboarding tools such as Grafana\nand Zabbix.\n- Familiarity with containerization technologies (Docker, Kubernetes).\n- Knowledge of CI/CD pipelines and integration with infrastructure\nautomation.\n- Experience with VMware-to-Nutanix migration or hybrid virtualization\nenvironments.\n- Strong communication and documentation skills.\nEducation:\n- Bachelor’s degree in Information Systems, Engineering,\nCybersecurity, or related technical field (or equivalent\nexperience).\nATR is an Equal Opportunity Employer (EOE) who
