Full Stack Tech Lead

We are growing rapidly and constantly expanding our global contactless payment ecosystem. We are looking for a leader who is hands-on enough to dive into the code, yet visionary enough to shape our architecture, drive our engineering culture, and deliver robust, cloud-native solutions.

Design and build high-performance microservices (Go, Java) and responsive, AI-driven web interfaces (Angular) using clean architecture principles. Architect and manage secure, cloud-native infrastructure (GCP, Kubernetes) and drive Infrastructure-as-Code and CI/CD pipelines. Optimize system performance across SQL/NoSQL databases and ensure platform reliability through comprehensive testing, observability, and zero-trust security. Mentor and coach engineers at all levels, while partnering closely with Product Managers to translate business requirements into scalable technical solutions.
