Platforma rychle roste a hledáme seniorního Python vývojáře, který naše datové služby zrobustní, naučí je zpracovat výrazně víc dat a zajistí, že se data spolehlivě dostanou k týmům, které je potřebují. Pracujeme s vlastním actor-based frameworkem, který kombinuje asyncio a multiprocessing a zvládá velké objemy real-time událostí. \n\nBudeš úzce spolupracovat s tradery a velmi chytrými vývojáři na náročných problémech a tvoje práce se rychle dostane do produkce.
