What is a senior network engineer?

Senior Network Engineers are experienced IT professionals responsible for designing, implementing, and managing complex computer networks within organizations. They oversee network infrastructure, troubleshoot issues, ensure network security, and optimize performance. Typically, they lead network projects, mentor junior staff, and collaborate with other IT teams to support business operations. Their expertise covers a range of technologies, including routers, switches, firewalls, and cloud networking.

What are some common challenges faced by senior network engineers when managing large-scale network infrastructures?

Senior Network Engineers often encounter challenges such as integrating new technologies into legacy systems, ensuring network security across a growing number of devices, and maintaining high availability while performing upgrades or troubleshooting. Balancing the demands of multiple stakeholders—like IT, security, and business units—can also be complex. Staying updated with evolving protocols and proactively identifying potential performance bottlenecks are crucial parts of effectively managing large-scale environments.

What does a senior network engineer do?

A senior network engineer builds and maintains data communication networks for a company or organization. As a senior network engineer, you have several years of industry experience and lead a team of junior network engineers and network administrators to ensure both the local area network (LAN) and wide area network (WAN) are functioning properly. Your job duties include installing software and hardware, creating a layout plan for cables, and troubleshooting and solving problems that arise with the networks for which you are responsible.

What is the difference between Senior Network Engineer vs Network Administrator?

AspectSenior Network EngineerNetwork Administrator
CertificationsCCNP, CCIE, Cisco certificationsCCNA, CompTIA Network+
Work EnvironmentDesign, implement, and troubleshoot complex networksMaintain and support existing network infrastructure
ResponsibilitiesNetwork architecture, advanced troubleshooting, project leadershipNetwork setup, monitoring, routine maintenance

While both roles involve network management, a Senior Network Engineer focuses on designing and implementing complex network solutions, often leading projects. In contrast, a Network Administrator primarily maintains and supports existing networks, ensuring smooth daily operations.

What are the key skills and qualifications needed to thrive as a senior network engineer, and why are they important?

To excel as a Senior Network Engineer, you need a deep understanding of network architecture, protocols, security, and typically a bachelor's degree in computer science or a related field. Expertise in configuring and troubleshooting routers, switches, firewalls, and experience with tools like Cisco IOS, Juniper, or cloud networking platforms, along with certifications such as CCNP or CCIE, are highly valued. Strong problem-solving abilities, communication skills, and leadership are crucial for designing solutions and collaborating with IT teams. These competencies ensure reliable, secure, and scalable network infrastructures that support critical business operations.

Job description

Senior Network Engineer
Leidos - National Security Sector | Cyber & Analytics Business Area
Make an Impact Where It Matters Most
Leidos is seeking a Senior Network Engineer to join our elite team supporting mission-critical national security programs. In this role, you'll work at the forefront of cybersecurity, network engineering, and advanced analytics-helping defend and enable some of the nation's most vital operations.
Our Cyber & Analytics Business Area (CABA) brings together experts in Security Engineering, Computer Network Operations (CNO), SIGINT, Mission Software, and Cryptographic Key Management. If you're looking for meaningful work, cutting-edge challenges, and a team that values innovation and expertise-you'll find it here.
Why Join Leidos?
We believe great work starts with supporting our people. That's why we offer:
  • Competitive compensation & 401(k) with 6% match (immediate vesting)
  • Generous PTO + 11 paid holidays
  • Flexible work schedules (no travel required for this role)
  • Paid parental leave
  • Education, training, and certification support
  • Technical upskilling & career growth opportunities
  • Employee stock purchase plan

At Leidos, your growth is part of our mission.
What You'll Do
As a Senior Network Engineer, you'll play a key role on a high-visibility, fast-paced program supporting multiple organizations from a centralized environment. You'll tackle complex challenges, influence network strategy, and mentor the next generation of engineers.
Your responsibilities will include:
  • Leading advanced network troubleshooting and problem resolution
  • Analyzing and optimizing network performance, latency, and throughput
  • Designing and implementing scalable, secure network architectures
  • Working with technologies such as:
    • Routing protocols & BGP
    • Policy-based routing & traffic shaping
    • IPSec tunneling & NAT
    • Firewalls, load balancing, and WAN optimization
  • Evaluating and integrating emerging networking technologies
  • Collaborating with cross-functional teams to deliver mission-driven solutions
  • Mentoring junior engineers (Levels 0-2) and ensuring engineering excellence
What You Bring
  • 12-15 years of network engineering experience (or equivalent expertise)
  • Bachelor's degree in a technical field (or 5 additional years of experience in lieu of degree)
  • Strong experience in network design, optimization, and security
  • CCNA and CCNP certifications required
  • Proven ability to lead technical efforts and mentor teams

Security Clearance Requirement:
  • Active TS/SCI with Polygraph (required)
Why This Role Stands Out
  • Work on a mission-critical program with real-world impact
  • Join a tight-knit, highly skilled team in a collaborative environment
  • Gain exposure to advanced technologies and high-level decision-making
  • Enjoy stability, growth, and purpose-all in one role
