Job description

Role Overview

We are seeking a motivated and capable System Administrator to join our Arlington, Texas office and support our executive, administrative, finance, and engineering teams. This role plays a key part in maintaining and improving our IT infrastructure in a fast‑paced, high‑accountability environment.

You will work hands‑on across systems, networking, and end‑user support while helping strengthen security, reliability, and operational efficiency. We value practical problem‑solving, ownership, and creative IT solutions that fit our business needs — not one‑size‑fits‑all enterprise models. This position partners closely with leadership and technical teams to ensure technology enables performance across the organization.

Key Responsibilities

Platforms & Identity Management

Administer and support Microsoft 365, including Entra ID and Intune for identity, device, and access management.
Manage Okta for SSO, MFA, and user lifecycle provisioning across integrated platforms.
Administer and maintain Twingate ZTNA to ensure secure, identity‑based remote access to internal resources.
Support and maintain Atlassian suite (Jira, Confluence, Bitbucket) to enable engineering and operational workflows.
Configure and manage Freshservice for IT service management and ticket lifecycle administration.
Develop and maintain scripts and automation (PowerShell, Bash, or similar) to streamline operations and improve system reliability.

Physical Infrastructure

Deploy, configure, and maintain physical servers in production environments (Proxmox and VMware).
Administer and support NAS systems, including storage provisioning, access control, and backup integration.
Build and maintain custom workstations and specialized systems to meet operational requirements.
Assist with installation, labeling, termination, and troubleshooting of structured network cabling as needed.

Network Infrastructure

Manage and support LAN environments built on the UniFi network stack.
Configure and maintain UniFi firewalls, switches, and wireless infrastructure across multiple locations.
Implement and troubleshoot routing, switching, and VLAN segmentation.
Configure and manage firewall rules, policies, and threat management features.
Support secure site‑to‑site and remote connectivity solutions as needed.

Qualifications

3+ years of hands‑on experience as a System Administrator or in a comparable infrastructure‑focused role.
Experience supporting and maintaining production IT environments across systems, networking, and end‑user platforms.
Strong troubleshooting skills with the ability to diagnose and resolve infrastructure and system issues independently.
Experience implementing IT systems, security best practices, and operational procedures.
Working knowledge of Linux environments (Ubuntu or similar) preferred.
Bachelor’s degree in Information Technology, Computer Science, or a related field.
Relevant industry certifications (Microsoft, VMware, CompTIA Network+/Linux+, CCNA, or similar).
Experience with Azure or hybrid cloud environments.
Exposure to Zero Trust security principles or modern identity‑driven access models.
Experience supporting multi‑site environments or structured infrastructure standards.
Experience in aerospace, defense, or manufacturing environments is a plus.
