As with any job, the roles and responsibilities depend on what company you work for. Internal operations and management differ significantly from company to company, meaning the job specifics can change a lot. That being said, almost every senior telecom analyst role will involve certain roles and responsibilities. 

Some of the most common include:

• Search for and discover network, system, or technological issues.
• Study problems and understand the roots of them. Develop detailed reports and graphs of analysis on each problem. 
• Create solutions to all network, system, or technological problems. 
• Design preventative solutions to stop issues from reoccurring in the same way.
• Create future telecommunications systems and equipment.
• Maintain current technologies, analyze them, and ensure that they are running smoothly without any problems. Optimize all systems and services.

Routine maintenance checks, troubleshooting, report generation, and information logging are core aspects of the role. Telecom analysts often have to provide training on the functionality and features of the telecommunications technology to users or customers.
