We are looking for a skilled and execution-driven Backend Engineer to design, build, and scale core backend services powering AllScales business. This role requires strong backend engineering fundamentals, hands-on experience with production systems, and the ability to work in high-performance, scalable environments.
Responsibilities
- 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.
- 3+ years of hands-on backend development experience in production environments.
- Strong proficiency in Python or Go; experience with both is a plus.
- Practical experience with backend frameworks:
- 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.
- Experience with microservices governance, including service discovery, circuit breaking, rate limiting, and observability (logging, monitoring, tracing).
- Experience leading or deeply contributing to the design and implementation of complex systems from 0 to 1.
- Open-source contributions, technical blogging, or public speaking experience.
