Full Stack Engineer; Android

We're on the search for a versatile Full Stack Engineer with strong Android experience to join our cutting-edge payment orchestration platform in Cape Town (hybrid).

In this role, you’ll be a pivotal part of the team responsible for building software that powers thousands of payment terminals used by merchants across South Africa. While you'll initially focus on building and enhancing our Android POS platform, the software that runs on physical payment terminals, this is fundamentally a full-stack role. You'll also work in the backend services that power those terminals, and supporting infrastructure to deliver reliable, scalable payment experiences.

As the business’ products evolve, you'll have opportunities to contribute across other engineering teams and stacks, so we're looking for engineers who enjoy solving complex problems regardless of where they exist in the stack.

The environment is highly dynamic and fast-paced. Your working mentality must be one of adaptability, resilience and passion. This is a fantastic company to work for with truly vast amounts of personal and professional upside.
