Job Description

Senior Network Engineer

Location: McLean, VA (On-site)
Type: Full-time
Base Salary Range: $130,000 - $150,000

Role Summary

We are seeking a full-time Senior Network Engineer to serve as a senior technical authority and individual contributor focused on network design, implementation, and complex problem resolution.

This role is ideal for an engineer who operates at the expert protocol level, leads through technical depth and execution excellence, and is trusted to design and deploy highly resilient enterprise and data center networks within a defined engagement period.

This position is deeply hands-on, with primary ownership of routing and switching architecture, implementation, and lifecycle improvements across enterprise, data center, and hybrid cloud environments.

Role Overview

The ideal candidate is a design-and-implementation-focused network engineer with mastery of routing and switching fundamentals and advanced architectures.

You will take ownership of large-scale network initiatives end-to-end, from requirements gathering and design through implementation, validation, and operational handoff.

This role requires CCNP certification , strong protocol-level knowledge, and the ability to translate business and security requirements into clear, buildable, and supportable network designs.

You will serve as a senior escalation point and technical mentor, helping establish engineering standards, reference designs, and best practices while remaining directly involved in implementation and troubleshooting.

Primary Responsibilities

• Design and implement enterprise, data center, and disaster recovery network solutions.

• Architect, deploy, and maintain highly available, fault-tolerant, and scalable routing and switching environments.

• Own routing and switching design and implementation, including BGP, OSPF, ECMP, segmentation, and control-plane protection.

• Perform expert-level troubleshooting for complex, multi-domain network issues using packet captures and protocol analysis.

• Design and implement data center, MDF/IDF, and access-layer network architectures, including segmentation and end-to-end deployment.

• Produce and maintain HLDs, LLDs, and implementation documentation for current and future-state designs.

• Execute technology evaluations, proofs of concept, and lab testing to validate design assumptions and operational impact.

• Collaborate with security, infrastructure, and cloud teams to ensure cohesive and secure network implementations.

• Contribute to network monitoring, telemetry, and self-healing designs to improve stability and mean time to resolution.

• Mentor mid- and senior-level engineers on routing, switching, and troubleshooting best practices.

• Ensure implementations align with security and compliance requirements, including NIST 800-53 where applicable.

Required Experience

• 8–12+ years of hands-on network engineering experience with a strong focus on routing and switching design and implementation.

• Proven experience deploying and operating mission-critical enterprise and data center networks.

• Demonstrated ability to act as a senior technical escalation point for complex network issues.

• Strong background in producing clear, implementation-ready network documentation.

Preferred Experience

• Experience in financial services or regulated enterprise environments.

• Experience supporting or mentoring other network engineers in complex environments.

Qualifications

Education

• Bachelor’s degree in Engineering, Computer Science, Telecommunications, or a related field preferred.

Certifications

• CCNP.

• Azure networking certification or equivalent experience is a plus.

Technical Expertise (Must Have)

• Routing: Expert-level design, implementation, and troubleshooting of BGP and OSPF.

• Switching: Advanced experience with Cisco IOS/XE, Nexus platforms, and Cisco ACI fabrics.

• Data Center Networking: Leaf-spine design, segmentation, and high-availability architectures.

• Firewalls: Experience integrating Palo Alto firewalls into enterprise and data center designs.

• SD-WAN: Experience implementing and supporting Prisma SD-WAN or similar technologies.

• Wireless: Experience deploying and operating Meraki wireless networks.

• Disaster Recovery: Network-level DR design, implementation, and validation.

• Identity & Access: Working knowledge of Cisco ISE and network-based access control.

• Monitoring & Telemetry: Experience with network monitoring tools and performance visibility.

• Packet Analysis: Expert-level packet capture and protocol analysis skills.

What Sets This Role Apart

This is not a management role . It is a senior, hands-on engineering engagement for a network engineer who wants to remain focused on designing and implementing complex networks rather than managing people or budgets.

You will be trusted to:

• Own complex routing and switching designs from concept to production.

• Implement solutions that become long-term architectural standards.

• Solve the hardest network problems in the environment.

Benefits

• Medical, dental, and vision insurance coverage.

• Employer-paid short-term disability, long-term disability, and life insurance.

• Paid time off with vacation (up to 10 days per year).

• Paid sick leave (up to 7 days per year).

• 401(k) retirement savings plan upon completing a year of the employment.

• Tuition reimbursement or assistance toward continuing education.

• Paid attendance at approved workshops and conferences.

• Full access to LinkedIn Learning.

• Employee Assistance Program (EAP).

Perks  (HQ Location)

• Complimentary daily office snacks and beverages.

• Professional development and ongoing learning opportunities.

• Employee recognition programs.

• Company-sponsored social events and team-building activities.

• Collaborative, team-oriented work environment.

• Opportunities to work on high-impact projects with experienced professionals.
