Java Full Stack Engineer (Tbilisi, Onsite) (вакансія неактивна)

Description
Astra Tech is a UAE-based company building one big app (Botim) where you can do everything: call, send messages, pay bills, move money, shop, book services, and even talk to AI — all without jumping between dozens of separate apps. By plugging new services into behaviours people already have (chat and calls), Astra Tech solves platform fatigue and creates a sticky ecosystem for 150M+ users across 155 countries.
Their flagship product, the Botim Ultra App, combines communication, fintech (Botim Money), e‑commerce, government services, and AI assistants under one brand, with a clear motto: “Blueprint of Simplicity” — make everyday life easier, not more complex
