But hiring a network engineer is not only about having someone on the team who can create or maintain a network.
A network engineer is responsible for setting up, developing, and maintaining computer networks within an organization. They also offer support to users, clients, customers, and troubleshoot any types of problems that may appear. One of their main objectives is to ensure the integrity of high availability network infrastructure.
To understand it better, let’s use a practical example. Last year when we thought the world was ending, instead of insisting on keeping your old, rusty business model, you decided that it was the perfect time to change things up. So, you shifted your onsite company towards a fully remote company. However, this was a major challenge because your company has more than 200 employees. You needed to create a structure that, besides being secure, was also easy for your employees to use for safe and easy access to the required applications. Also, to secure all the company’s data and all the relevant information. How to do this? By hiring a network engineer who makes sure to build a safe network suitable for your company and its employees.
