About the Role
As a Senior Full-Stack Developer, you will architect and own both the front-end and back-end of our enterprise-grade casino platform. You’ll work on high-traffic, real-time systems — building scalable APIs and microservices, crafting performant player-facing interfaces, and integrating with casino providers, payment gateways, and responsible gaming tools. You will be a key technical voice across the stack, ensuring security, scalability, and quality at every layer.
