Senior Java Backend Developer (FinTech) Offline
About the company
We have spent five years building the relationships, regulatory strategy, and proprietary technology to weave the Global South into a connected financial ecosystem. Our core stack which forms part of our broader ecosystem is a fully integrated digital banking system with current accounts, savings, multi-currency accounts, payments, onboarding, lending origination and servicing, document management, regulatory reporting, and full general ledger and accounting — built natively rather than layered on legacy technology.
Role Overview
We are looking for a senior-level backend developer who can design and build the backend of our cloud-native banking platform. The ideal candidate is a strong communicator, can work autonomously on complex systems, and brings deep expertise in modern JVM-based software development for distributed microservices in Java and Scala, CI/CD, and Kubernetes. Operational security and regulatory best-practice should always be front of mind.
