LOCATION

Limassol, Almaty, Yerevan, Tbilisi

ChillBase studio is an independent and innovative player in the gaming industry. We’re fueled by our passion for crafting outstanding products.

Our ongoing projects are in full swing, and we’re dedicated to delivering top-notch work without being tied down by a strict corporate structure.

We’re looking for a Rust Backend Developer to join the team building the server platform for our game OneState. The platform powers key game systems, including player accounts and sessions, the in-game and web stores, payments and subscriptions, reward delivery, promotional mechanics, experiments, and analytics.

We’re looking for someone who can write production-ready code and independently take a task from requirements to release and validation in production. You should have a strong understanding of transactions, API compatibility, event delivery, external system failures, and the challenges of building reliable distributed services.
