Site Reliability Engineer

System uptime and reliability

What this life looks like

You make sure the internet keeps working. Site Reliability Engineers combine software engineering and operations expertise to build and maintain highly reliable, scalable systems. When millions of people use a service simultaneously, SREs are the reason it does not fall over.

What she actually does

You define and enforce reliability standards including uptime targets (Service Level Objectives), build monitoring and alerting systems, respond to and investigate production incidents, automate repetitive operational tasks, design systems that are resilient to failure, conduct post-incident reviews to prevent recurrence, and continuously work to reduce toil — the manual, repetitive work that slows teams down.

Where you can work

SectorPlaces in Africa
Fintech PlatformsFlutterwave, Paystack, Interswitch, OPay — payment systems with critical uptime requirements
E-CommerceJumia, Takealot — platforms processing high traffic and transaction volumes
TelecomsMTN, Safaricom — network reliability engineering teams
Global Tech with African EngineersGoogle, Microsoft, Amazon — all employ African SREs in Africa and remotely

Why it matters in Africa

As African tech companies such as Flutterwave and Paystack scale to millions of users, ensuring their systems remain available 24 hours a day is critical. A payment system that goes down loses real money and destroys user trust. SREs who can build reliability into African fintech and e-commerce platforms are in growing demand.

Your pathway in

  • Build a strong foundation in software engineering first — SRE is an advanced discipline
  • Study Computer Science or Software Engineering at university
  • Learn Linux, networking fundamentals, and cloud platforms thoroughly
  • Develop expertise in monitoring tools (Prometheus, Grafana, Datadog) and incident management
  • Read the free Google Site Reliability Engineering book at sre.google/sre-book

Skills you will need

  • Linux and system administration
  • Monitoring and observability tools
  • Incident management and on-call
  • Automation and scripting (Python, Go, Bash)
  • Cloud platforms
  • Communication under pressure
