Our client is a leading South African Fintech company, driving a more inclusive and connected economy for over two decades. Through an extensive nationwide merchant network, they provide access to essential digital products and services — including airtime, electricity, bill payments, and other everyday transactions — helping bridge the gap for cash-based customers often excluded from traditional digital finance. The business has built deep roots in South Africa's informal retail sector, serving more than 25 million cash-based customers, and continues to expand through partnerships with major retail brands and corporates locally and internationally.
They are looking for a Senior Full Stack Developer to join a well-established Fintech platform, supporting and enhancing a multi-faceted technology stack and its third-party integrations.

- Take responsibility for managing and executing deployments with precision and care.
- Share expertise on systems to empower the team and foster a learning culture.
- Develop and maintain robust Disaster Recovery procedures to ensure system resilience and reliability.
- Work confidently with cross-functional teams (e.g., Design, Legal, Data, Risk) to communicate the developer team's work and ensure alignment with broader organisational goals.
- Regularly mentor less experienced developers, providing constructive feedback on designs and technical approaches; support onboarding of new developers.
- Escalate issues beyond your team or individual work scope when necessary, ensuring successful resolution through appropriate channels.
- Demonstrate expertise in non-functional aspects like accessibility, performance, and security, and advocate for and teach these practices.
