FanDuel runs America's largest sportsbook and iGaming operation, handling real-money transactions, live odds, and player accounts for millions of users daily across sports betting, casino games, daily fantasy sports, and horse racing. Founded in 2009, the company sits at the intersection of regulated financial systems and high-traffic consumer tech - meaning the threat surface is broad: payment fraud, account takeover, DDoS against live betting windows, credential stuffing at scale, and the compliance demands that come with operating in a heavily regulated, state-by-state legal landscape.
The security work spans real-time systems where latency matters, platform infrastructure that needs to stay up during peak sporting events, and responsible gaming tooling that has regulatory teeth. You're defending infrastructure that processes actual money on tight timelines - odds shift in seconds, bets close, payouts execute. That's a live attack surface with financial incentive baked in. The tech stack supports high-throughput, low-latency pipelines, and the engineering culture emphasizes both speed and quality, with teams expected to operate in ambiguous, fast-moving conditions.
FanDuel's geographic footprint is primarily U.S.-based, and the regulatory patchwork across states means compliance and security are tightly coupled. The company signals an innovation-focused, fast-paced environment where building software that matters is a stated value - not just shipping features, but shipping them responsibly under real scrutiny. For security engineers, the draw is a system where the stakes are concrete, the data is sensitive, and the attack surface never sleeps.
