We are seeking a Senior Backend Developer (Consultant) to accelerate the modernization of our core platform, moving from a monolithic legacy system to a highly distributed, cloud-native architecture. In this role, you will lead the integration of features across 5–6 cross-functional teams, acting as a driving technical force without needing formal authority. A core immediate focus will be contributing to our Single Sign-On (SSO) authentication platform. The ideal candidate embraces ambiguity, designs robust yet pragmatic solutions without over-engineering, and can execute efficiently leveraging AI-assisted coding tools like GitHub Copilot.
