TwinSpires Tech Stack

Online wagering platform for horse racing, sports, and casino gaming

Gambling Facilities and Casinos Louisville, KY 201–500 employees Public Company

TwinSpires operates a multi-channel wagering platform (desktop, mobile, app, retail) anchored in horse racing but expanding into sports betting and casino. The tech stack is Java-heavy with Kotlin and Android native development, AWS infrastructure, and testing-focused tooling (Selenium, TestRail, BrowserStack) — typical of a consumer-facing platform handling high transaction volume. Current hiring is engineering-led with mid-level seniority dominance, and active projects signal investment in AI/LLM features and player engagement mechanics, though internal pain points (low engagement, turnover, marketing process friction) suggest operational challenges beyond product.
