Job Description

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

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.

• 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.
