Telecommunications Engineer
Communication networks
What this life looks like
You build the networks that connect Africa. Telecommunications Engineers design, build, and maintain the infrastructure that carries voice calls, internet data, and television signals across cities, countries, and continents. Africa's mobile revolution — the fastest in the world — was built by telecom engineers.
What she actually does
You design mobile network coverage, plan and optimize radio frequency systems, install and commission base stations and transmission equipment, manage network capacity to handle growing traffic, troubleshoot network performance issues, plan fibre optic cable routes, design satellite communication systems, and work on next-generation 4G and 5G network rollouts.
Where you can work
| Sector | Places in Africa |
|---|---|
| Mobile Network Operators | MTN Group, Airtel Africa, Safaricom, Glo, Orange Africa — network engineering and operations |
| Equipment Vendors | Ericsson (multiple Africa offices), Huawei Africa, Nokia Africa — deploying network equipment |
| Internet Service Providers | Liquid Intelligent Technologies, MainOne (Equinix), Seacom — fibre networks |
| Regulatory Bodies | NCC Nigeria, CA Kenya, ICASA South Africa — spectrum management and licensing |
Why it matters in Africa
Africa has over 700 million mobile subscribers and continues to add new users rapidly. The 5G rollout is underway in South Africa, Nigeria, and Kenya. Submarine cable systems are bringing international bandwidth to African shores. Every megabit of connectivity that reaches an African home, school, or clinic passes through infrastructure designed by telecom engineers.

A woman in this field
Funke Opeke
Nigeria
Funke is the founder of MainOne, which built West Africa's first private submarine cable connecting the region to global internet infrastructure. With a degree in electrical engineering from Obafemi Awolowo University and a career at major US telecoms companies including Verizon and NYNEX, she returned to Nigeria and built one of West Africa's most transformative telecoms infrastructure companies. Forbes included her in the World's Top 50 Women in Tech in 2018.
