What is a Senior CS Core Network Engineer?

Senior CS Core Network Engineers are experienced professionals who design, implement, and maintain the core elements of a telecommunications network, specifically the Circuit Switched (CS) core. They ensure reliable voice and data communication by managing network components such as MSCs (Mobile Switching Centers), HLRs (Home Location Registers), and gateways. Their responsibilities also include troubleshooting, optimizing network performance, integrating new technologies, and supporting large-scale network upgrades. Typically, these engineers work closely with other network teams and vendors to maintain service quality and network security.

How does a Senior CS Core Network Engineer typically collaborate with cross-functional teams during network upgrades or optimizations?

As a Senior CS Core Network Engineer, you will frequently collaborate with teams such as radio network engineers, transmission specialists, and IT support during network upgrades or optimization projects. This collaboration involves joint planning sessions, troubleshooting calls, and integrating solutions to ensure seamless voice and data services. You’ll often act as a technical lead, coordinating with vendors and internal stakeholders to implement changes with minimal service disruption. Effective communication and documentation are key, as you’ll need to translate complex core network requirements into actionable tasks for other teams.

What are the key skills and qualifications needed to thrive as a Senior CS Core Network Engineer, and why are they important?

To thrive as a Senior CS Core Network Engineer, you need deep expertise in mobile core network architecture, signaling protocols (such as SS7, SIP, and Diameter), and a relevant engineering degree. Experience with core network equipment (e.g., Ericsson, Huawei, Nokia), network monitoring tools, and certifications like CCNP or vendor-specific credentials are typically required. Strong analytical thinking, problem-solving abilities, and effective communication help you collaborate with cross-functional teams and troubleshoot complex issues. These skills ensure reliable network performance, rapid resolution of outages, and the successful implementation of new services in telecom environments.

The Senior Cs Core Network Engineer focuses on designing and maintaining core network infrastructure, requiring advanced certifications and technical expertise. In contrast, a Network Operations Center (NOC) Engineer primarily monitors and supports existing networks, often working in a 24/7 environment. Both roles are vital in telecommunications and large enterprise networks but differ in scope and responsibilities.

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
