Job description

Network engineers (also called network architects) plan, construct and manage networks to ensure they’re optimized and functioning as intended. 

As a network engineer, you’ll have responsibility for setting up, developing and maintaining computer networks within an organisation or between organisations. You’ll offer support to users, who can be staff, clients, customers and suppliers, and troubleshoot any problems that arise.

As a network engineer, you’ll need to:

establish the networking environment by designing system configuration, directing system installation and defining, documenting and enforcing system standards

design and implement new solutions and improve resilience of the current environment

maximize network performance by monitoring performance, troubleshooting network problems and outages, scheduling upgrades and collaborating with network architects on network optimization

undertake data network fault investigations in local and wide area environments using information from multiple sources

secure network systems by establishing and enforcing policies, and defining and monitoring access

support and administer firewall environments in line with IT security policy

report network operational status by gathering and prioritizing information and managing projects

upgrade data network equipment to the latest stable firmware releases

configure routing and switching equipment, hosted IP voice services and firewalls

provide remote support to on-site engineers and end users/customers during installation

provide remote troubleshooting and fault finding if issues occur upon initial installation

undertake capacity management and audit of IP addressing and hosted devices within data centers

liaise with project management teams, third-line engineers and service desk engineers on a regular basis

speak to customers via email and phone for initial requirement capture

Your role will depend to a certain extent on the sector you work in and the size of your organization. For example, in a large investment bank you may have specific responsibility for one area of the system, whereas in a small company you may need to troubleshoot for any IT-related problem that arises.
