作为该团队的资深后端工程师,你的职责包括在现有系统上进行性能诊断、主导重构、推动开发规范与最佳实践,以及参与内部工具和集成管线的临时现代化项目。此岗位强调以根因分析为导向的故障分析与持续改进。

Qualifications

  • 5年以上 Java 后端开发实战经验。
  • 中级至高级的 Spring Boot 和微服务架构能力。
  • 具备 Redis 和 Kafka 的实际使用经验--能够诊断问题并给出配置方案。
  • 熟悉反向代理概念和 Nginx
  • 具备关系型和非关系型数据库经验,包括查询层面的性能分析
  • 熟悉 Git、CI/CD 工作流及软件开发最佳实践
  • 具备 AI 辅助开发工具的使用经验,能够审慎审查 AI 生成的代码

Responsabilités

Description du poste

关于岗位我们现有的工程团队负责功能开发。目前,我们正在组建一支新的团队,专注于现有后端系统的优化、重构和现代化改造。作为该团队的高级后端工程师,你的工作重点不是开发新功能,而是提升现有系统的性能、可靠性和可维护性--既包括主动的优化工作,也包括在生产问题出现时进行深入架构分析。我们同时期望你将AI辅助开发工具(如 Cursor、GitHub Copilot)作为日常工作流程的核心组成部分--用于分析代码、加速开发、提升效率。同样重要的是,你需要对每一份产出负全责:审查、验证并确认其正确性、安全性和可维护性。AI 加速你的工作,但不替代你的判断。

  • Python 开发经验
About the Role

Our existing engineering team handles feature development, and we are now forming a new team focused on optimizing, refactoring, and modernizing our existing backend systems.As a Senior Backend Engineer on this team, your focus will not be building new features. You will improve the performance, reliability, and maintainability of the systems we already run - both proactively and in response to production issues that require deeper architectural analysis. We also expect you to use AI-assisted development tools (e.g., Cursor, GitHub Copilot) as a core part of your workflow - to analyze code, accelerate implementation, and improve productivity. What we equally expect is full ownership: you review, validate, and approve every output for correctness, security, and maintainability. AI accelerates your work; It does not replace your judgment.

What You’ll Do
  • Maintain working knowledge of existing system architecture and design decisions to advise on the performance impact of new changes
  • Identify and resolve performance bottlenecks across our legacy Java-based backend services, database layers, and middleware
  • Lead refactoring and modernization initiatives to improve system maintainability and scalability
  • Investigate production issues spanning application logic, database performance, middleware, and network layers - with root cause analysis, not just patching
  • Propose and champion development standards and best practices across the engineering department
  • Contribute to ad‑hoc modernization projects (internal tooling, integration pipelines) as priorities dictate
  • Explore and integrate AI tooling and agents into development workflows and processes
What We’re Looking For
Required:
  • 5+ years of hands‑on Java backend development experience
  • Intermediate to advanced proficiency with Spring Boot and microservices architecture
  • Working knowledge of Redis and Kafka - enough to diagnose issues and specify configurations
  • Familiarity with reverse proxy concepts and Nginx
  • Experience with relational and NoSQL databases, including query‑level performance analysis
  • Familiarity with Git, CI/CD workflows, and software development best practices
  • Experience with AI‑assisted development tools and the ability to critically review AI‑generated code
Preferred (not required):
  • Docker / Kubernetes
  • Observability and monitoring tools (e.g., Prometheus, Grafana, ELK)
  • Python development experience
