Swish Analytics is a machine-learning driven sports-odds and predictive-data company that builds a real-time odds origination engine for sportsbooks and fantasy platforms. It provides hyper-accurate player prop pricing, match and team markets, in-play and pre-game projections, and automated bet-lifecycle management to power bookmaking, bet builders, parlays, and micro-markets. Swish positions itself as a B2B provider focused on automation, accuracy, and scalable odds infrastructure for the sports betting industry.

📋 Description

• Architect and build the core trading systems that execute our fair value models across sports betting exchanges at scale • Design event-driven trading systems that consume fair value models and market data to make sub-second execution decisions • Build the core logic for comparing fair values against live market prices and determining when/where to trade • Implement asynchronous order generation, submission, and cancellation workflows across multiple venues with different latency profiles • Design state machines for order lifecycle management (pending, accepted, filled, cancelled, rejected) with proper event ordering and idempotency • Build venue-specific integrations (WebSocket connections to Matchbook, Kalshi; REST API adapters for Betfair; FIX protocol handlers) • Implement intelligent order routing that selects optimal venues based on liquidity, fees, latency, and position constraints • Design coordination logic for managing orders across multiple venues when a single bet spans several platforms • Handle venue-specific quirks (rate limiting, connection drops, partial fills, odds movement during submission) • Build real-time position tracking systems that aggregate exposure across all venues, markets, and event types • Implement global liability management that enforces risk limits while maximizing capital utilization • Design systems that detect and respond to position drift (when actual fills deviate from intended exposure) • Create reconciliation engines that validate positions against venue reports and detect/resolve discrepancies • Design data pipelines that ingest real-time market data from multiple feeds (WebSocket streams, REST polling, custom adapters) into low-latency in-memory stores • Build efficient order book representation and query systems optimized for fast fair value lookups • Implement message ordering and deduplication logic for ensuring consistent state across async operations • Design persistent logging and event sourcing for order/trade auditing and post-incident analysis

🎯 Requirements

• 3+ years building production trading/market-making systems for betting syndicates, sharp groups, or exchanges • Deep understanding of exchange vs. bookmaker dynamics and practical experience executing against both • Hands-on experience integrating with real-time sports betting data feeds and exchange APIs • 3+ years of production Python with expert-level async/await, event loop, and concurrent execution skills • Strong system design for distributed, real-time, event-driven systems • Deep understanding of database transactions, consistency models, and state management under high throughput • Experience with message streaming platforms (Kafka or equivalent) for order/execution event handling • Proficiency with containerization (Docker), orchestration (Kubernetes), and cloud infrastructure (AWS, GCP)
