Job Description

As a Network Security Engineer (L2) at NTT DATA, your role will be to ensure that our clients' security infrastructures and systems remain operational. With a proactive approach, you'll monitor, identify, investigate, and resolve technical incidents and problems, restoring service efficiently. Your primary objective will be to handle client requests or tickets with technical expertise, ensuring they are resolved within the agreed service level agreement (SLA). You'll actively manage work queues, perform operational tasks, and update tickets with resolution actions. By identifying issues and errors early on, you'll log incidents promptly and provide second-level support, communicating effectively with other teams and clients to extend support when needed. Your role includes executing changes responsibly, flagging risks and mitigation plans, and ensuring all changes have proper approvals. Collaborative efforts are at the heart of this role. You'll work closely with automation teams to optimize efforts and automate routine tasks, ensuring seamless handovers during shift changes. Your analytical skills will be key in auditing incident and request tickets for quality, recommending improvements, and contributing to trend analysis reports to identify automation opportunities. As a go-to for initial client escalations, you'll assist L1 Security Engineers with triage and troubleshooting, and support project work when required. Your contributions to the change management process will ensure thorough documentation, effective planning and execution of maintenance activities, and compliance with standard procedures. This is a fully remote role. Candidate must be based in Spain or Czech Republic with valid work permit.
