Senior Site Reliability Engineer

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

Wave is one of the fastest-growing financial services ever. You’ll help us gracefully handle that growth by designing simple, resilient, and observable systems that can keep up with demand.

Our to-do list changes constantly, but here are some recent projects as examples of what you might work 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 delayed 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.

Requirements

• You care a lot about working on software whose mission you can believe in.
• You have at least 5 years of professional experience working as a software engineer and at least 2 years on site reliability.
• You’ve worked with cloud-based environments and networking.
