Description

Systems Network Administrator (TS/SCI w/ Poly)

Leidos – National Security Sector | Cyber & Analytics Business Area (CABA)

Make a Difference in National Security

Leidos has an exciting opportunity for a Systems Network Administrator to join our National Security Sector’s Cyber & Analytics Business Area (CABA). Our team is at the cutting edge of Security Engineering, Computer Network Operations (CNO), Mission Software, SIGINT, and advanced analytics—delivering solutions that directly support critical national security missions.

If you’re looking for meaningful work, a collaborative team environment, and opportunities to grow your technical skills, this is the role for you.

Why Join Leidos?

We believe in supporting our employees both professionally and personally. That’s why we offer:

401(k) with 6% company match + immediate vesting
Generous PTO + 11 paid holidays
Flexible work schedules
Paid parental leave
Technical upskilling, training, and education support
Employee stock purchase plan
And much more

What You’ll Do

In this role, you’ll be a key part of a small, high-performing team supporting enterprise IT systems and end users. You’ll:

Support the implementation, troubleshooting, and maintenance of IT systems
Manage and monitor client/server, storage, and network environments
Provide Tier 1 (Help Desk) and Tier 2 (escalation) support
Troubleshoot system issues and apply patches, updates, and configuration changes
Manage user accounts, password resets, VPN access, and PKI-related tasks
Configure and maintain Windows, Linux, and UNIX systems
Support virtualized and storage environments
Document processes, SOPs, and troubleshooting procedures
Contribute to reports and technical deliverables
Use ticketing systems and internal tools to track and resolve issues

You’ll also provide hands-on support to users both at headquarters and across the enterprise—delivering excellent customer service while managing multiple priorities.

Work Environment

On-site support: Monday–Friday, 8:00 AM – 4:00 PM
Small team environment (<10 people) with strong collaboration
Direct interaction with end users and mission stakeholders

What You Bring

You’re a problem-solver who enjoys working in dynamic environments and supporting mission-critical systems.

Basic Qualifications

5+ years of experience as a Systems Administrator (or similar role)
Bachelor’s degree in a technical field. Experience can be used in lieu of degree
Active TS/SCI with Polygraph (required)
CompTIA Security+ (current)

Accepted Certifications (one required)

CompTIA Security+
Microsoft Technology Associate (MTA-IT Infrastructure)
MCSA – Desktop (Windows 7 or Windows 8)
MCITP – Windows Client (Desktop Support or Desktop Administrator)

Why This Role Stands Out

At Leidos, you won’t just be another administrator—you’ll be part of a mission-driven team where your work has real impact. We provide challenging assignments, modern technologies, and a clear path for career growth.

If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo — because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.

Original Posting:

April 28, 2026

For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Pay Range:

Pay Range $59,150.00 - $106,925.00

The Leidos pay range for this job level is a general guideline only and not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.

About Leidos

Leidos is an industry and technology leader serving government and commercial customers with smarter, more efficient digital and mission innovations. Headquartered in Reston, Virginia, with 47,000 global employees, Leidos reported annual revenues of approximately $16.7 billion for the fiscal year ended January 3, 2025. For more information, visit www.Leidos.com.

Pay and Benefits

Pay and benefits are fundamental to any career decision. That's why we craft compensation packages that reflect the importance of the work we do for our customers. Employment benefits include competitive compensation, Health and Wellness programs, Income Protection, Paid Leave and Retirement. More details are available at www.leidos.com/careers/pay-benefits.

Securing Your Data

Beware of fake employment opportunities using Leidos’ name. Leidos will never ask you to provide payment-related information during any part of the employment application process (i.e., ask you for money), nor will Leidos ever advance money as part of the hiring process (i.e., send you a check or money order before doing any work). Further, Leidos will only communicate with you through emails that are generated by the Leidos.com automated system – never from free commercial services (e.g., Gmail, Yahoo, Hotmail) or via WhatsApp, Telegram, etc. If you received an email purporting to be from Leidos that asks for payment-related information or any other personal information (e.g., about you or your previous employer), and you are concerned about its legitimacy, please make us aware immediately by emailing us at [email protected].

If you believe you are the victim of a scam, contact your local law enforcement and report the incident to the U.S. Federal Trade Commission.

Commitment to Non-Discrimination

All qualified applicants will receive consideration for employment without regard to sex, race, ethnicity, age, national origin, citizenship, religion, physical or mental disability, medical condition, genetic information, pregnancy, family structure, marital status, ancestry, domestic partner status, sexual orientation, gender identity or expression, veteran or military status, or any other basis prohibited by law. Leidos will also consider for employment qualified applicants with criminal histories consistent with relevant laws.
