Front to back. End to end. Built for millions.
Own the full picture.
Most engineers own a layer. You'll own the stack.
As a senior full stack engineer, you'll lead end-to-end initiatives, design complete solutions and provide technical leadership across the entire application stack – from the interface a client taps on our app to the back-end systems processing their claim in real time.
Capitec Insurance is making a significant move into South Africa's insurance market, with 23 million banking clients and a three-year growth plan that demands technology built to scale. We're committed to making life cover more affordable, transparent and simple – with a fully digital application that takes less than 10 minutes and no medical tests.
Every line of code you write is part of keeping that promise.

• Drive technical standards across the team

• Optimise performance across the entire stack
• Integrate complex systems across our insurance platform
• Balance front-end UX with back-end performance – so clients feel the quality of what you build

What's in it for you
This is where full stack engineers do some of their most complete work.
You're not looking for a role where you're siloed into one layer. You want to see the whole system, lead across it and build something that people use. Here's what we offer.

Work that matters beyond the sprint
