• Work with real-time data pipelines and event-driven systems (Kafka, Redis)
• Handle large-scale data processing and low-latency systems
• Ensure code quality through code reviews, testing, and best practices
• Deliver end-to-end: from design → development → testing → production
• Collaborate closely with product, data, and platform teams

What we’re looking for
• 1–5 years of experience in Backend Engineering
• Strong experience with Java (Spring Boot)
• Solid understanding of Data Structures & Algorithms
• Good foundation in OOP & SOLID principles
• Experience with SQL/NoSQL (MySQL, PostgreSQL, MongoDB)
• Hands-on with Microservices & RESTful APIs
• Familiar with Kafka, Redis or similar systems
• Strong plus (highly preferred for this role)
• Experience working with high-performance, low-latency systems
• Hands-on with large-scale or real-time data processing
• Understanding of distributed systems & system design

Experience with:
• Data processing frameworks (e.g. Spark, Flink)
• OLAP / analytics DB (e.g. Doris, StarRocks, ClickHouse)
• Search systems (e.g. Elasticsearch)
• Experience with Docker/Kubernetes & Cloud environments

Ideal candidate
• Strong problem-solving mindset (not just coding)
• Able to work independently and handle complex systems
• Comfortable working in fast-moving, high-scale environments
• Eager to learn and go deeper into system design & data platform
