- Design, develop, and maintain core backend services, including API design, business logic implementation, and system optimization.

- Build high-performance and scalable backend services using Python (FastAPI, Django, Flask) or Go (Gin, Echo, Fiber).

- Participate in database schema design, optimization, and maintenance using relational databases (MySQL, PostgreSQL) and NoSQL solutions (MongoDB, etc.) where appropriate.

- Write and maintain clear API documentation, unit tests, and integration tests to ensure system stability and long-term maintainability.

- Analyze system performance and address challenges related to high concurrency, high availability, and scalability.

- Contribute to backend architecture design and refactoring, promoting microservices, modularity, and standardization.

- Collaborate closely with frontend, product, QA, and DevOps teams to deliver features with high quality and on schedule.

- Troubleshoot, debug, and resolve production issues to ensure system reliability and uptime.

Requirements

- Bachelors degree in Computer Science or a related field is preferred.

- Python: FastAPI, Django, Flask

- Go: Gin, Echo, Fiber, or similar

- Solid knowledge of relational databases (MySQL, PostgreSQL), strong SQL skills, and experience with query optimization.

- Experience working with caching systems such as Redis, including understanding common caching challenges (cache penetration, breakdown, avalanche).

- Familiarity with distributed system concepts: microservices, message queues (Kafka, RabbitMQ, RocketMQ), task queues, and idempotency design.

- Basic Linux operation skills and familiarity with Docker, Kubernetes, and CI/CD pipelines.

- Strong coding standards, attention to testing and documentation, and a systematic problem-solving approach.

Nice to Have

- Hands-on experience with high-concurrency, high-availability, and large-scale data systems.
