Staff Frontend Engineer

Scorewarrior is a game developer and publisher based in Limassol, Cyprus.

We are working on Total Battle — a cross-platform MMO 4X strategy game with a deep social system and extensive player interaction. We have 2 million monthly active players and are continuing to grow, with the goal of becoming the #1 game in the genre.

Our team consists of 200+ passionate, talented, self-driven, and continually developing professionals who love making high-quality games.

At Scorewarrior, we're making a long-term investment in Building Blocks — a new generation of self-service internal products with clear interfaces, contracts, and documentation that game teams can adopt independently.

Today, Localization Hub, together with Crowdin, powers localization workflows across Scorewarrior — from translation tracking, analytics, and reporting to automated translation quality checks and an AI-powered localization assistant.

Our next goal is to transform Localization Hub into the first fully self-service Building Block, enabling content teams to localize standard features independently while the lead focuses on high-level decisions.

The engineering team behind Localization Hub will establish the architecture, engineering standards, and practices that future Building Blocks will build upon.
