Pragmatike is hiring on behalf of a fast-growing, product-focused crypto technology company building a real-time wallet for professional traders. The product is performance-critical, data-intensive, and designed for users who operate at high frequency and expect instant feedback, reliability, and precision. The engineering team is intentionally small, senior, and highly technical, operating with a startup mindset: fast execution, strong ownership, and zero tolerance for unnecessary complexity.

• Own complex UI features end-to-end, from technical design to production delivery
• Build and optimize components consuming live data streams (WebSocket, SSE, REST)
• Implement robust state management for high-frequency updates and user interactions
• Collaborate closely with senior engineers and product leads in short iteration cycles
• Profile and optimize frontend performance to meet low-latency requirements
• Contribute to technical decisions and frontend architecture evolution
• Ensure high code quality, maintainability, and scalability across the codebase

Technology Stack

• Frontend: React, Vite, TypeScript
• State Management: TanStack, Zustand
• Styling: TailwindCSS
• Realtime: WebSocket, SSE, REST APIs
• Platform: Chrome Extension (Manifest V3)
• Tooling & Analytics: Privy, PostHog
• Charts: TradingView, Lightweight Charts, or similar
