The GN&T Network Security team is looking for a highly motivated and experienced Cybersecurity Engineer to join the Network Security Defense team. The Defense teams are responsible for owning the security lifecycle and effectiveness across the Core, Edge, and Access networks, as well as all systems and network functions within GN&T.

In this role, you will be critical in advancing our security posture through real-time Threat Monitoring & Detection using SIEM tools like Splunk, leading Incident Response efforts during a breach, and managing the continuous Vulnerability Management lifecycle across networks and applications. The position also requires expertise in defining and implementing robust Security Architecture, including firewalls, encryption, centralized Identity and Access Management, and Multi-Factor Authentication (MFA). A strong candidate will also possess advanced Threat Hunting skills, including Advanced Networking & Protocol Analysis, Endpoint & Memory Forensics, Data Science & Querying, and demonstrable experience in Automation & Scripting to enhance our Cybersecurity tooling.

Candidates are expected to possess requisite expertise encompassing the design and deployment of comprehensive security architectures, including firewalls, encryption, Identity and Access Management (IAM), and Multi-Factor Authentication (MFA). This expertise extends to the securing and hardening of management networks, particularly those utilized for telemetry. Furthermore, a strong foundation in network fundamentals (TCP/IP, DNS, flow data) is essential for effective discernment of malicious traffic. Responsibilities include managing security projects aimed at vulnerability remediation in collaboration with engineering teams, as well as the development and meticulous refinement of threat detection capabilities within Security Information and Event Management (SIEM) platforms, such as Splunk.

Key Responsibilities:

• Support Security Improvements: Support the identification of security gaps and lead the design, architecture, and implementation of appropriate security solutions.

• Collaborative Design: Partner across Operations, Engineering, and Planning organizations to ensure secure design patterns are embedded into new deployments and major changes.

• Strategic Problem Solving: Work with lead engineers on strategic security technical challenges and complex investigations.

• Incident Analysis: Provide expert analysis during active incidents, support root cause analysis, and produce clear reports outlining timelines, impact, and remediation.

• Security Assessments: Perform regular security control assessments to validate configuration effectiveness and close gaps discovered during active hunts.

• Technical Communication: Articulate complex technical concepts clearly to diverse internal and external audiences.
