Senior Security 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 2017, we launched a mobile app in Senegal for cash deposit, withdrawal, and peer-to-peer and business payments.

Now, we have millions of users across 9 countries 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

We’re looking for an experienced security engineer who’s independent, excited about getting things done, and ready to hit the ground running.

You'll primarily be responsible for our application security, working with our product teams to work on new systems to enhance our security posture.

Our customers trust us with their money, and you’ll be at the forefront of making sure we retain that trust!

This broadly scoped role will allow you to get your hands on many different types of security projects, from direct application security to helping our infrastructure team think about security for our databases.

As we integrate AI-powered agents into our engineering and operations workflows, you'll help define and enforce the guardrails around how we use them safely.

This includes securing agentic tooling against prompt injection, excessive permissions, and data exfiltration — and building the policies and technical controls to govern AI usage across the company.

Some experience with common industry certifications like ISO-27001 and PCI-DSS would be beneficial, although you won’t be expected to run or oversee audits.

Our to-do list changes constantly, but here are some recent projects:

About Engineering at Wave

You'll report to the Security Team Lead and work closely with the CISO, as part of a small 4 person security team, likely rotating with many of our Product and Platform teams, depending on the project you’re working on.

Each team is led by a product manager and mentored by a technical lead on the team.

You’ll be responsible for your own security projects as well as supporting the engineering organisation on security through advice and design review.

We organize things to give you as much ownership as possible, so you'll typically be in charge of your projects from planning to delivery.
