What are Senior CS Core Network Engineers?

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.

What is the difference between Senior Cs Core Network Engineer vs Network Operations Center (NOC) Engineer?

CertificationsCCNA, CCNP, Cisco certificationsCCNA, Network+
Work EnvironmentDesign, optimize, and troubleshoot core network infrastructureMonitor, maintain, and support network systems
Industry UsageTelecommunications, ISPs, large enterprisesTelecom providers, managed service providers

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.

    KEY:
    Senior AWS Network Engineers to execute a large-scale redesign and segmentation of CS Disco's AWS network. Resources will not architect but will execute under a Staff Engineer / Architect, focusing on VPC design, segmentation, ingress/egress controls, security hardening, and operational networking work to reduce SOX/security risk and improve platform reliability.
    Job Description:
    Senior AWS Network Engineer
    Role Summary
    CS Disco is seeking Senior AWS Network Engineers to execute a large-scale redesign and segmentation of its AWS networking environment as the company transitions from a startup-era platform to an enterprise-grade, SOX-compliant operating model. This role is execution-focused-not architectural-working under a Staff Engineer / Architect to implement VPC redesigns, segmentation strategies, ingress/egress controls, and security hardening. The work directly reduces board-level security risk while improving platform reliability and developer experience.
    Applicable Job Titles
    • Senior Network Engineer
    • Senior AWS Network Engineer
    • Network Engineer
    • Network Architect
    • Lead Network Engineer
    • Network Administrator

    Top Critical Skills & Experience (What Success Requires)
    • Deep AWS Networking Execution Experience (7+ years)
      Proven hands-on experience building and modifying VPCs, subnets, routing, gateways, and security constructs at scale-no ramp-up required.
    • Network Segmentation & Security Controls (7+ years)
      Demonstrated ability to isolate environments, control east/west and north/south traffic flows, and reduce overly permissive communication patterns in regulated environments.
    • Operational Execution & Reliability Focus (7+ years)
      Strong operational mindset with experience creating runbooks, handling remediation, and executing day-to-day networking work while parallelizing large initiatives.
    • Enterprise Security & Compliance Awareness
      Experience supporting SOX-driven or audit-driven environments, understanding how networking decisions impact risk posture and governance.
    • Execution Under Architectural Direction
      Comfortable executing defined designs under a Staff Engineer / Architect without owning end-state architecture.

    Required Skills, Tools, Technologies & Services
    AWS Networking
    • Amazon VPC design and restructuring
    • Subnets, route tables, IGW/NAT Gateways
    • Ingress and egress traffic controls
    • Environment isolation and traffic segmentation

    Network Segmentation & Security
    • Traffic isolation strategies
    • Reduction of hair-pinning and overly permissive access
    • Security hardening aligned with compliance expectations
    • Support for audit and board-visible risk reduction

    Operational Execution
    • Ongoing AWS networking operations
    • Runbook creation and maintenance
    • Incident remediation and reliability improvements
    • Parallel execution of networking initiatives to unblock platform teams

    Collaboration & Delivery
    • Work closely with Staff Engineer / Architect
    • Enable developers by abstracting networking complexity
    • Execute changes without disrupting business operations

    Nice-to-Have / Secondary Skills
    • Experience in high-growth SaaS or startup-to-enterprise transitions
    • Exposure to large-scale AWS environments with multiple teams
    • Familiarity with governance, audit, or security review processes

    Business Context & Impact
    • CS Disco is moving from startup speed to enterprise governance
    • Current AWS networking architecture presents high SOX and security risk
    • Board-level urgency to improve security posture and platform reliability
    • Internal teams are capacity-constrained and need senior execution support
    • Goal is a mature platform where developers do not need to understand networking

    Employee Value Proposition (EVP)
    • High-impact AWS network redesign with board-level visibility
    • Greenfield enterprise security hardening work
    • Solve real AWS-at-scale networking problems
    • Clear architectural leadership and direction
    • Not a maintenance-only role-focused on meaningful, lasting change

    Location & Workplace
    • Workplace Type: 100% Remote
