What is a 2nd line support engineer?

2nd Line Support Engineers are IT professionals who handle more complex technical issues that cannot be resolved by the first line (helpdesk) support team. They provide advanced troubleshooting, diagnostics, and solutions for hardware, software, and network problems. These engineers often interact with end users and other IT teams to ensure issues are resolved efficiently. They may also be responsible for escalating unresolved problems to higher-level specialists or third-line support. 2nd Line Support Engineers play a crucial role in maintaining business continuity and minimizing downtime.
