We're building the most advanced crypto casino platform in the world—and we’re just getting started.
We’re looking for a Senior Frontend Engineer who excels at building high-performance, interactive web applications. You’ll own the front-end architecture for our gaming experiences, optimize complex rendering pipelines, craft rich real-time interfaces, and push the limits of what’s possible in browser-based gaming.

* Own frontend implementation for interactive product flows across wallets, balances, gameplay, account features, promotions, and real-time updates.
* Collaborate with engineers on frontend architecture, reusable components, state management, and performance optimization.
* Build and refine real-time client-server features using technologies like Socket.IO, WebSockets, and event-driven updates.
* Contribute to game-facing frontend experiences involving animations, sound, timing, physics, and responsive interaction patterns.
* Partner closely with product managers, designers, backend engineers, and QA to deliver polished end-to-end features.
* Use Cursor IDE, LLMs, and AI-assisted coding workflows heavily as part of day-to-day engineering, including MCP-powered integrations and custom tooling on top of Cursor.
* Use observability practices and tools like Datadog to understand frontend health, debug production issues, and improve user impact.
* Write maintainable, tested code and contribute to code reviews, CI/CD workflows, and team engineering standards.
