About The Role

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.

We're looking for a Senior Front-End Engineer who can architect, optimize, and scale complex front-end systems handling live market data and trading interactions. This role is ideal for engineers who enjoy deep frontend work, performance tuning, and building sophisticated UIs close to the core product.

• 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
  
  

What Were Looking For

• 5+ years of experience in front-end engineering
• Deep expertise in React, TypeScript, and modern state management patterns
• Proven ability to architect and own full features with minimal oversight
• Experience building data-intensive or real-time applications
• Strong understanding of frontend performance optimization and profiling
• Comfortable working in a startup environment with high autonomy
• Familiarity with crypto products, trading platforms, or financial dashboards
• Clear product mindset and strong attention to UX for power users
  
  

Bonus Points

• Experience building Chrome Extensions (Manifest V3)
• Prior work on crypto exchanges, wallets, or trading tools
• Experience with Privy or other embedded wallet solutions
• Familiarity with charting libraries (TradingView, Lightweight Charts, etc.)
• Crypto-native background with understanding of wallets, tokens, and on-chain concepts
  
  

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
