System Administrator - Linux / Onsite Customer Support

We were early to the fight against Ubiquitous Technical Surveillance, and we've been pushing the edge ever since.

Our mission is to help government and enterprise organizations understand and manage commercial data risks, shape their digital signatures, and operate with confidence in an increasingly complex information landscape. We build and integrate advanced, tech-forward solutions to problems our customers often don't know they have - until it matters most.

We move fast, think critically, and deliver where it counts.

What's in it for you?

We work hard and do fun things.

You'll work on high-impact, technically challenging problems alongside a team that values teamwork over competition. Veilant offers a solid work-life balance and flexible remote work options. At Veilant, you'll work with the most talented software developers, systems engineers, and subject matter experts, building tools and systems that make a real difference.

We are looking for a motivated System Administrator with strong Linux experience to provide direct, onsite support. This role is ideal for an early-career systems professional who enjoys being hands-on, solving technical issues directly with users, and supporting mission-critical systems in a customer-facing environment.

You will serve as a key onsite technical resource supporting customer workstations, system administration activities, troubleshooting, and day-to-day operational needs. While the environment includes both Linux and Windows systems, we are looking for someone who is Linux-heavy and comfortable supporting a mixed technical environment.

This is a high-visibility role where you will work directly with customer users, internal technical teams, the Network Operations Center, and engineering resources to keep systems running smoothly.

What You'll Do

In this role, you will provide onsite system administration and technical support across a range of customer technologies, including physical and virtual workstations, Linux and Windows systems, printers, VoIP phones, and internal platforms.

Your responsibilities will include:

• Provide daily onsite support for customer users, systems, and technical infrastructure.
• Perform system administration tasks in a Linux-forward environment.
• Support Windows desktops and workstations as needed.
• Troubleshoot issues across physical workstations, virtual workstations, printers, VoIP phones, and related customer technology.
• Support and administer our multi-mission platform, including troubleshooting problems as they arise.
• Act as an onsite liaison between the customer, internal Network Operations Center, and engineering teams.
• Escalate complex technical issues to the appropriate internal teams while maintaining customer communication.
• Help ensure customer systems remain operational, responsive, and properly supported during business hours.
• Work closely with existing onsite personnel during onboarding and transition periods.

What Success Looks Like in the First 6 Months

By the end of your first six months, you will have become a trusted onsite technical resource for the customer. You will understand the customer's environment, common support needs, escalation paths, and daily operational expectations.

Success in this role means you are able to:

• Independently troubleshoot and resolve common Linux, Windows, workstation, printer, VoIP, and platform-related issues.
• Support our multi-mission platform with confidence, including routine administrative tasks and issue resolution.
• Build strong working relationships with customer users and internal technical teams.
• Know when to resolve issues directly and when to escalate to the NOC or engineering team.
• Maintain a reliable onsite presence during customer business hours (8a - 5p)
• Help reduce dependency on existing onsite staff by taking ownership of daily support activities.

Who Will Thrive in This Role

This role is a great fit for someone who likes being close to the customer and close to the technology. You do not need to be a senior engineer, but you should be dependable, technically curious, and comfortable taking ownership of problems from first report through resolution or escalation.

The ideal candidate is someone who:

• Has a few solid years of system administration experience.
• Technically curious, have a home lab? Let's talk about it!
• Is strongest in Linux but flexible enough to support Windows when needed.

• Hands-on Linux administration experience.
• Experience supporting Windows desktops or workstations.
• Ability to troubleshoot technical issues across user workstations, virtual environments, peripherals, and customer-facing systems.
• Comfortable working onsite at a customer facility five days per week.
• Strong communication skills and the ability to interact professionally with customer users.
• Ability to escalate issues clearly and effectively to operations or engineering teams.
• Willingness to support a mixed environment that includes Linux, Windows, physical systems, virtual systems, printers, and VoIP phones.

Nice to haves:

• Experience supporting mission, government, defense, or cleared customer environments.
• Familiarity with virtual workstation environments.
