Frontend Developer Jobs in iGaming

Frontend developers in iGaming ship the surfaces players actually touch: casino lobbies rendering thousands of game tiles with fast search, sportsbook UIs where odds update live over websockets, and registration and deposit flows tuned relentlessly for conversion. Game launch integration is its own craft, embedding third-party game clients through aggregator APIs and handling sessions, currencies, and mobile quirks.

Promo surfaces are heavily A/B tested, so teams expect comfort with experimentation frameworks and per-market feature flags, since a banner legal in one country may be forbidden in another. React, Vue, and TypeScript dominate, with performance budgets driven by mobile traffic. Many teams hire remote across Europe.

Frequently asked questions

What is special about sportsbook frontend work?
The UI is a live data problem. Odds, markets, and cashout values stream continuously, and the bet slip must reconcile price changes at the moment of placement without confusing the player. State management and websocket handling are core interview topics.
What does game launch integration involve?
Casino games come from dozens of external studios via aggregators. Frontend engineers embed those game clients, pass session tokens and currency context, handle resize and orientation on mobile, and deal with each provider's quirks in a consistent lobby experience.
How much A/B testing should I expect?
A lot. Lobbies, promo banners, and deposit flows are tested constantly because small conversion gains compound across large player bases. Experience with experimentation tooling and feature flags is a genuine advantage.
