About The Team

The Service Stability Engineering Team envisions service stability as one of the core competitive strengths of the company's products. By building end‑to‑end, link‑level risk management capabilities, the team aims to achieve sustainable automatic identification and analysis of stability risks, transforming from "reactive governance" to "proactive governance". This approach shifts more stability‑related matters forward and addresses them early, preventing issues before they arise and enhancing user experience.

What We Look For In You

• Bachelor's degree or higher in Computer Science or a related field, with over 7 years of experience in development and architecture.
• Proficiency in Java, hands‑on experience with the Spring Cloud microservices technology stack, solid computer science fundamentals, and a grasp of Linux, storage, and network I/O principles.
• Possess experience in high‑concurrency distributed system architecture or high‑concurrency scenario component design and development, with an understanding of Java concurrency libraries.
• Understanding of core Middleware technologies like Nginx, Redis, ElasticSearch, Kafka, MySQL, Docker and Kubernetes.
• In‑depth understanding of the business architecture currently managed, alongside a strong methodology for architectural design.
• Capable of rationalizing architectural designs for new business lines and providing targeted optimization suggestions.
