I’m looking for an experienced backend engineer to help build a real-time prediction market arbitrage bot that monitors and executes trades across Kalshi and Polymarket. The bot will: • Ingest live market data via REST & WebSocket APIs • Match equivalent events across platforms (e.g., elections, finance, crypto) • Detect arbitrage opportunities after fees and slippage • Execute trades safely using limit orders and risk controls • Provide monitoring, logging, and alerting This is a serious, production-grade project, not a simple bot. Experience with trading systems, order books, low-latency data processing, and risk management is required. Key Responsibilities • Integrate Kalshi & Polymarket APIs (market data + trading) • Implement event matching and arbitrage logic • Handle slippage, partial fills, and execution safety • Build clean, testable backend services
