Job Description

Lead Full Stack Engineer

Weekday (YC W21)

• Lead the full stack development of the trading terminal, making decisions regarding architecture, technology stack, code quality, and release schedules. • Develop the real-time trading UI with React/Next.js, including features such as the market discovery grid, analysis dashboards with live charts, order entry/betslip, position tracking, and an automated strategy builder. • Design and build backend APIs (Node.js/Python) for aggregating market data, routing trade executions (Polymarket CLOB, Kalshi), tracking portfolio and P&L, and managing users. • Implement WebSocket infrastructure to stream live odds, order book depth, in-play probability updates, and position mark-to-market data, ensuring sub-second latency from source to UI. • Integrate with prediction market APIs (Polymarket Gamma API, CLOB/CTF Exchange, Kalshi) and sportsbook feeds to normalize market data and enable cross-platform trade execution. • Build the on-chain transaction layer, including wallet integration, CLOB order signing, USDC settlements, and transaction status monitoring on Polygon. • Create the frontend for the automation engine—a rule builder UI allowing traders to configure 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 ownership of performance tuning, focusing on bundle size, rendering efficiency for data-heavy grids, WebSocket connection management, API response times, and caching mechanisms. • Recruit and mentor junior and mid-level engineers as the team grows, implementing code review standards, maintaining engineering documentation, and facilitating technical onboarding.

Job Requirements

  • Over 6 years of full stack engineering experience, including at least 2 years in a lead or senior role responsible for end-to-end product delivery.
  • Advanced proficiency in React (Next.js preferred), with expertise in managing complex state (Zustand/Redux), real-time data rendering, WebSocket integration, and optimizing performance for data-intensive UIs.
  • Strong backend development skills in Node.js (Express/Fastify) or Python (FastAPI/Flask), with experience in RESTful API design, authentication (JWT/OAuth), rate limiting, and horizontal scaling.
  • Hands-on experience with WebSockets or Server-Sent Events for real-time streaming applications such as trading platforms, dashboards, or live feeds.
  • Skilled in using PostgreSQL, Redis, and message queues (Kafka/RabbitMQ/BullMQ) within event-driven architecture frameworks.
  • Experience working with cloud infrastructure (AWS or GCP), containerization (Docker), CI/CD pipelines (GitHub Actions), and monitoring/observability systems.
  • A strong sense of UI/UX design, capable of translating intricate data into clear, compact, and trader-friendly interfaces reminiscent of Bloomberg or TradingView, rather than generic dashboards.
  • Familiarity with Git workflow practices, code review culture, and agile/sprint-based development methodologies.
  • Excellent and structured English communication skills, with the ability to explain 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: Knowledge of charting libraries (TradingView Lightweight Charts, D3, Recharts) and large-scale data visualization.
