Senior Frontend Developer (React + Next.js + MUI)
We’re building a next-generation game marketplace — a platform where users can launch and play games from integrated providers, all in one place. We’re looking for a Senior Frontend Engineer who can take full ownership of the UI layer, using React, Next.js, and MUI / MUI X.
Backend is fully handled in-house — you’ll focus 100% on the frontend.
Your Responsibilities:
• Architect and build a modern, fast frontend using React (Next.js)
• Adapt existing and Create scalable components and complex interfaces using MUI / MUI X
• Integrate with external game provider APIs and payment gateways
• Build admin tools, user dashboards, and modular game launch flows
• Optimize performance (SSR, lazy loading, etc.) and maintain code quality
• Collaborate with product, backend, and UI/UX teams
Must-Have Experience:
• 5+ years in React / Next.js development
• Expert-level knowledge of MUI / MUI X — this is a core requirement
• Confident in working with complex APIs and dynamic data flows
• Hands-on experience with payment systems (nice to have experience Centrobill, Epoch)
• Comfortable building systems from scratch — architecture, logic, components
• Experience with marketplaces or gaming platforms
Nice to Have:
• Familiarity with SSR optimization, caching, i18n
• Worked on admin panels, permission-based UIs, or multi-tenant system
