Lead Full Stack Engineer

This is a fully remote position, open to applicants in India.

📋 Description

• Oversee the comprehensive development of the trading terminal, making key decisions about architecture, technology stack, code quality, and release timelines.

• Create the real-time trading user interface using React/Next.js, incorporating features like the market discovery grid, analysis dashboards with live charts, order entry/betslip, position tracking, and an automated strategy builder.

• Design and implement backend APIs (Node.js/Python) for aggregating market data, facilitating trade executions (Polymarket CLOB, Kalshi), monitoring portfolio and P&L, and user management.

• Establish WebSocket infrastructure to deliver live odds, order book depth, in-play probability updates, and position mark-to-market data, ensuring sub-second latency from source to user interface.

• Integrate with prediction market APIs (Polymarket Gamma API, CLOB/CTF Exchange, Kalshi) and sportsbook feeds to standardize market data and support cross-platform trade execution.

• Develop the on-chain transaction layer, which includes wallet integration, CLOB order signing, USDC settlements, and monitoring transaction status on Polygon.

• Create the frontend for the automation engine—a rule builder user interface that allows traders to set up automated strategies with entry/exit triggers, Kelly-sized position management, and multi-leg hedging.

• Establish CI/CD pipelines, testing frameworks (unit, integration, end-to-end), monitoring and observability tools (Sentry, Datadog/Grafana), and deployment processes utilizing Docker and AWS/GCP.

• Take charge of performance optimization, concentrating on bundle size, rendering efficiency for data-heavy grids, WebSocket connection management, API response times, and caching strategies.

• Recruit and mentor junior and mid-level engineers as the team expands, implementing standards for code review, maintaining engineering documentation, and facilitating technical onboarding.

⛳️ Requirements

• More than 6 years of full stack engineering experience, including at least 2 years in a lead or senior position responsible for complete product delivery.

• Advanced expertise in React (with a preference for Next.js), focusing on managing complex state (Zustand/Redux), real-time data rendering, WebSocket integration, and enhancing performance for data-intensive user interfaces.

• Strong backend development capabilities in Node.js (Express/Fastify) or Python (FastAPI/Flask), with a background in RESTful API design, authentication (JWT/OAuth), rate limiting, and horizontal scaling.

• Practical experience with WebSockets or Server-Sent Events for real-time streaming applications such as trading platforms, dashboards, or live feeds.

• Proficient in using PostgreSQL, Redis, and message queues (Kafka/RabbitMQ/BullMQ) within event-driven architecture frameworks.

• Familiarity with cloud infrastructure (AWS or GCP), containerization (Docker), CI/CD pipelines (GitHub Actions), and monitoring/observability systems.

• A keen eye for UI/UX design, able to convert complex data into clear, concise, and trader-friendly interfaces reminiscent of Bloomberg or TradingView, rather than generic dashboards.

• Knowledge of Git workflow practices, a strong code review culture, and agile/sprint-based development methodologies.

• Exceptional and structured English communication skills, capable of articulating technical decisions to non-technical stakeholders.

• Preferred: Experience with Web3/blockchain integration (ethers.js, wallet connectors, on-chain transactions), crypto trading platforms, or fintech products.

• Preferred: Familiarity with charting libraries (TradingView Lightweight Charts, D3, Recharts) and large-scale data visualization.

🏝️ Benefits

• Competitive salary and performance-based bonuses.

• Flexible working hours and remote work options.

• Opportunities for professional growth and development.

• Collaborative and innovative work environment.

• Comprehensive health and wellness benefits.
