In addition, digital transformation brings with it the need for greater agility and scalability of networks, an aspect that the system engineer must take into account when designing and updating the business infrastructure.

Skills and soft skills: a necessary balance

To become a good network system engineer, it is not enough to be an expert in technology: it is also essential to develop a set of soft skills that can integrate and reinforce technical knowledge. Un balance between hard skills and soft skills It is essential to face the daily challenges related to the management of business networks, where technical decisions must be accompanied by interpersonal and problem solving skills.

Hard skills: the fundamental technical skills

1. Knowledge of network technologies

A network system engineer must have a solid knowledge of IP networks, communication protocols and the configuration of network devices, such as routers and switches. This means understanding how networks work at a theoretical level, but also being able to put this knowledge into practice during design and implementation of ICT solutions.

2. Network security management

The network system engineer must know implement and manage security solutions to protect business data from external and internal threats. This includes configuring firewalls, intrusion detection systems (IDS/IPS), Virtual Private Network (VPN) to protect data during transmission, and advanced authentication systems to ensure that only authorized users can access sensitive resources. Security is not only an initial design phase, but it must be constantly monitored and updated to face new threats.

3. Monitoring and troubleshooting

Networks are dynamic systems that can suffer failures or degradation in performance. A good system engineer must be able to monitors constantly using advanced diagnostic tools to identify possible problems, slowdowns or failures. When a problem occurs, the system engineer must act promptly, with an in-depth analysis, to resolve the fault in the shortest possible time, minimizing disruptions and ensuring the company's operational continuity.

Soft skills: soft skills that make the difference

1. Communication skills

One of the most important soft skills for a network system engineer is communication. While technical skills are critical, a systems engineer must be able to clearly explain complex issues to non-technical colleagues and superiors, such as business managers or managers. It must also be able to communicate effectively with other teams, such as engineering, IT and support teams, to coordinate interventions or share crucial information. The ability to write clear reports and updates on project progress is equally important to ensure that all parties involved are aligned.

2. Teamwork

A network engineer rarely works in isolation. Managing complex networks requires a strong collaboration with other professionals: engineers, developers, security analysts and other technical figures. Knowing how to work in a team, sharing knowledge and solving problems collectively is essential. Communication within the team and the management of complex projects are skills that allow obtaining the best results, especially in business environments where the network is an integral part of daily operations.

3. Analytical thinking and result orientation

When a technical problem occurs, the system engineer must be able to break it down into smaller parts and deal with it methodically to arrive at a solution. Likewise, in network design activities, critical thinking helps evaluate the best solutions to optimize performance, improve security and reduce operating costs. THEresult-orientation It is another important skill, as the system engineer must make decisions that support long-term business objectives, such as scalability and network sustainability.

4. Adaptability and continuous updating

The system engineer must be able to quickly learn new technologies, such as artificial intelligence applied to network management or new security solutions, and integrate them effectively into the business environment. Continuous learning not only improves skills, but also makes it possible to anticipate the company's future needs.

ICT solutions and the role of digital transformation

The management of corporate networks is undergoing a radical change in a context increasingly influenced by digital transformation.
