Senior Software Engineer; Back End

Build banking for the businesses South Africa forgot. This space is still being shaped. You'd help shape it.

Most engineering roles ask you to build on what's already decided. This one asks you to help decide what gets built.

We need a senior engineer who leads technical initiatives, designs complex systems and drives architectural decisions – in a space that is still emerging. The team is building banking services for entrepreneurs, small businesses and side-hustlers who haven't had suitable products before. The engineering you do here has a direct line to real economic change for people who have been underserved for too long.
