What you'll be doing...

The Global Network & Technology team seeks highly motivated Network Security Engineer to secure and harden Verizon's Telemetry networks.

This role requires candidates to translate high-level security frameworks into concrete configurations for telemetry devices, focusing on security implementation beyond a standard firewall scope. The role requires deep expertise in network protocols, hands-on experience with routers/switches, SIEM tools (especially SPLUNK and ISE), and a strong focus on automation, threat detection, incident response, and continuous security validation across the organization. The Principal Engineer will specifically set strategic direction and define architectural patterns for long-term resilience.

• Lead the design, architecture, and implementation of cutting-edge network security solutions to address technology gaps.

• Act as the security subject matter expert in network design reviews, ensuring that all network assets meet stringent carrier-grade security standards and embed secure design patterns.

• Drive continuous improvement of network visibility and telemetry collection, conduct proactive threat hunting, and serve as escalation support for network security incidents.

• Execute root cause analysis for incidents, perform regular security control assessments, and lead strategic security solution implementation in a highly scalable environment. Design, develop, and refine high-fidelity detection logic to identify adversarial behavior across the network.

• Develop essential technical documentation, including Playbooks, Confluence pages, Network diagrams, and Method of Procedures (MOPs).

• Drive security architecture, lead policy implementation, manage incident response, and integrate security principles early into the development lifecycle.

• Leverage tools or custom automation, eg, Python, Ansible playbooks to run automated audits against security benchmarks, ensuring zero configuration drift.

• Proactively search for signs of lateral movement, exfiltration, and persistence within the environment using the MITRE ATT&CK framework as a guide.

• Analyze network logs and configurations to identify vulnerabilities, recommend & build proactive mitigations.

• Develop comprehensive assessment reports and provide prioritized recommendations for remediations.

• Identifying opportunities to mentor, guide, and delegate technical documentation/tasks to support the team and broader organization
