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?

• 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
