Communications Engineer

Overview

Communications engineers design, build, and maintain the invisible networks like 5G and fibre optics that keep the entire world connected.

Description

  • Design and map out high-speed telecommunication networks.
  • Troubleshoot network outages or signal disruptions, rerouting data to keep critical services running.
  • Upgrade older communication hardware and software.
  • Coordinate with field technicians, government regulators, and software developers to install new infrastructure securely.
  • Test system security and bandwidth capacity to prevent network crashes during usage spikes.

Entry requirements

  • You will need a Diploma or Degree in Electrical and Electronic Engineering, Telecommunications, or Computer Science.
  • You should also be familiar with network protocols, cloud computing, and radio frequency systems. Professional certifications like Cisco or cloud computing credentials are highly valuable bonuses.

Salary

$3,200 – 5,700

Trivia

As of 2025, Singapore became one of the first countries globally to achieve full 5G coverage across its entire underground MRT network, a feat that required engineers to reconfigure thousands of legacy 3G/4G hardware points within tunnels.

What to expect

Stay adaptable and curious, because network tech evolves incredibly fast. You’ll have to both monitor network data in office and go on-site to inspect physical hardware.

Frequently asked questions

Software engineers build apps and websites people use every day like Instagram or TikTok. Communications engineers focus on building "digital highways" - the network infrastructure that allows those apps to travel from server to phone without lagging.

Not exactly. While basic coding definitely helps to automate tasks, their focus is more on how hardware like cables and software connect. It's more about understanding massive system architecture than writing lines of code.

The immediate priority is strategically rerouting data traffic to backup networks to keep critical services like hospitals and banks online, thereafter, they hunt down the root cause of the crash.

Because data demands are exploding globally, their focus shifts from just "maintaining" network to "scaling" it. They have to redesign and upgrade systems to handle massive data loads so millions can use it simultaneously without crashing the grid.

Because they never work alone. They have to explain complex, invisible network issues to non-technical bosses. If they can't clearly explain why the company needs to invest millions in a new 5G tower, their network designs will never get funded.
