Description

We are seeking a highly skilled Backend Data Developer to join our Data Core Team , responsible for building the foundational infrastructure that powers our high-scale distributed product.

This role combines backend engineering excellence with deep familiarity in modern data systems.

You will design and implement infrastructure components, data services, and internal frameworks using Java, working with technologies such as OpenSearch, ClickHouse, and Kafka.

You will solve complex distributed challenges, address real-world production issues, and ensure our platform remains fast, resilient, and scalable.
