Job Title: Linux Systems Engineer

Job Location: Springfield, VA

Compensation: $125,000 - $145,000

Eligibility/Clearance: Candidate must possess an active TS/SCI clearance

and be willing to obtain a CI Polygraph

The Linux Systems Engineer is an active participant in SAFe and Scrum

development teams and meetings. The systems engineer will be responsible

for supporting the customer’s enterprise environment.

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.
