Junior Linux System Administrator

Job Description

Junior Linux System Administrator (Recruiting for Axellio)

Axellio ( headquartered in Colorado Springs, Colorado, is an innovator in advanced high-speed streaming data capture, storage, and distribution, high-performance networking, RF technologies, and innovative cyber solutions. We design and deliver cutting-edge platforms that enable customers to process, retain, distribute, analyze, and move massive amounts of data at the edge—where speed, reliability, and performance matter most.

We're searching for a Junior Linux System Administrator who is passionate about Linux, enjoys solving complex technical challenges, and wants to work with industry-leading technologies. This is a unique opportunity to support and enhance revolutionary products while collaborating with talented engineers and technical leaders who are pushing the boundaries of edge computing. Success in this role requires strong troubleshooting skills, a critical-thinking mindset, and the ability to thrive in a fast-paced, hands-on environment. If you're naturally curious, enjoy tackling difficult problems, and have a "get it done" attitude, you'll have the opportunity to make a meaningful impact on technologies that support demanding commercial, government, and defense applications. If you're ready to work on innovative systems that combine Linux, networking, RF, and next-generation computing technologies, we'd love to hear from you.

Summary:

As a Junior Linux System Administrator, you will support Axellio’s Private and Government Customers in deploying, installing, and troubleshooting Axellio’s Xpress solutions and contracted platforms. This is a hands-on, physical-layer infrastructure and technical support role — installing, cabling, and sustaining enterprise servers, network, and virtualization platforms in commercial and secured DoD/military environments. The ideal candidate has deep, working knowledge of Linux and real hands-on comfort with physical network infrastructure (cabling, TAPs, SPAN ports), paired with strong customer-facing troubleshooting instincts and a demonstrated habit of learning new technology on their own initiative. This is a junior to mid-level role with a clear growth path into automation, virtualization, and advanced infrastructure engineering — you do not need to arrive with that depth, but you do need to arrive with the appetite for it.

You will collaborate with cross-functional teams, including sales, professional services, development, and cyber, to provide technical assistance during pre-sales, troubleshoot production systems, and support new or upgraded deployments. The ideal candidate possesses strong hands-on technical instincts, a willingness to learn, and the ability to thrive in a dynamic, customer-facing environment.

Core Responsibilities (Primary):

\n
• As a 24/7/365 organization, shift work, night shifts, holidays, and on-call responsibilities are required, and travel to customer sites globally up to 25% of the time is required.
\n
• Install, configure, and troubleshoot enterprise servers, operating systems, and networking equipment — switches, firewalls, hardware components, VLANs, physical cabling, TAPs/SPAN ports.
\n
• Diagnose and resolve physical-layer connectivity issues (transceiver mismatches, fiber contamination, cable/mode mismatches) using standard troubleshooting procedures.
\n
• Administer and troubleshoot Linux operating systems (RHEL and RHEL-based) day-to-day using the command line interface.
\n
• Represent Axellio product delivery (Xpress platform and solutions); own the delivery of and manage customer experience with Axellio-developed appliances and software.
\n
• Provide on-site and remote technical support and troubleshooting for customers.
\n
• Document system and network configurations, changes, and operational processes.
\n

Essential Qualifications:

\n
• U.S. Citizen holding an active Security Clearance
\n
• Ability to travel worldwide up to 25%.
\n
• Deep, working technical knowledge of command line Linux — able to navigate, administer, and troubleshoot systems independently, not just execute basic commands.
\n
• 3+ years of hands-on experience in information systems, networking, or computer science, OR a Computer Science degree.
\n
• Hands-on experience with physical network infrastructure — cabling, TAPs/SPAN ports, physical installation, and troubleshooting (not just conceptual understanding).
\n
• Candidates should have a primary background in technical/systems support and network infrastructure. Applicants with exclusively cybersecurity experience and no hands-on server/network infrastructure administration will not be considered.
\n
• Customer-facing technical support experience.
\n
• A demonstrated pattern of self-directed technical learning — able to speak to a specific example from the past year (personal project, home lab, certification pursued on your own initiative).
\n

Additional Preferred Qualifications:

\n
• Exposure to Bash scripting and Ansible (prior use is a plus — production automation ownership is not expected).
\n
• Familiarity with virtualization and container platforms.
\n
• Familiarity with RMF/STIG-adjacent concepts is a plus.
\n

What You Get:

\n
• Base compensation in the $80,000 to $120,000 commensurate with experience.
\n
• Office location: Colorado Springs, CO — in office minimum 3 days/week (5 days to start)
\n
• Medical, dental, vision insurance with company paid STD and LTD + life insurance.
\n
• 401k + company match & flexible paid time off.
\n
• Equity stock options so that you can share in business success.
\n
• The chance to develop next generation products and work with others who are passionate about technology.
\n
• A team driven by collaboration and getting results in a fast paced and transparent start-up environment where trying new things, “failing fast,” and learning are valued.
