Job description

Lead Software Engineer | Johannesburg | Permanent

Lead from the front, stay hands-on and help shape the next generation of secure, scalable software. This is an opportunity for an experienced full stack engineer to combine technical leadership with meaningful contribution across architecture, engineering and AI-enabled product development.

As Lead Software Engineer, you will provide hands-on technical leadership to a cross-functional development squad, owning solution design and contributing production-grade code across the front-end, back-end, APIs and database layers. You will help set engineering standards, make architectural decisions, drive modern DevOps and testing practices, and ensure solutions are secure, maintainable and fit for purpose.
