Our mission

We're making Africa the first cashless continent.

In 2017, over half the population in Sub-Saharan Africa had no bank account. That's for good reason—the fees are too high, the closest branch can be miles away, and nobody takes cards. Without access to financial institutions, people are forced to keep their savings under the mattress. Small business owners rely on lenders who charge extortionate rates. Parents spend hours waiting in line to pay school fees in cash.

We're solving this by building financial services that just work: no account fees, instantly available, and accepted everywhere. In places where electricity, water and roads don't always work, you can still send money with Wave. In November 2017, we launched a mobile app in Senegal for cash deposit, withdrawal, and peer-to-peer and business payments. In 2019, we expanded to Cote d'Ivoire. Now, we have millions of users and are growing fast. Our goal is to make Africa the first cashless continent. And that's where you come in....

How you'll help us achieve it

You’ll lead the Reliability team, which ensures that Wave’s backend stays as close to “always up” as possible, and can scale as our userbase grows. Reliability is extremely important to Wave for two reasons:

  1. We’re one of the fastest-growing financial services ever, which causes a steady stream of new load-induced issues to resolve.
  2. We’ve become critical infrastructure for many of our users—if we go down, they can’t access their money.

Because of this, it’s one of our top engineering priorities.

About the Reliability Team

The Reliability team’s scope includes:

  • Building tooling to observe and debug outages and performance problems
  • Hardening Wave’s backend to be more resilient to incidents
  • Enabling product teams to discover and fix reliability / performance issues in code they own
  • Responding to incidents, analyzing postmortems, and prioritizing the resulting action items

Some recent projects, as examples of specific things the team has worked on:

  • Improve the throughput of our double-entry accounting ledger by tracking down subtle edge cases in Postgres’ implementation of serializable isolation.
  • Scale our database by introducing read replicas while preserving within-session read-your-writes consistency.
  • Build load-testing infrastructure to make sure we’re ready to handle, e.g., millions of sheep purchases during Tabaski.
