Frontend Engineer at Deepcoin

Job Description:

Key Responsibilities:

• Rendering Service Optimization & Disaster Recovery
  • Design and optimize Server-Side Rendering (SSR) architecture to achieve high-performance rendering and dynamic degradation strategies, ensuring service availability in high-concurrency scenarios.
  • Develop disaster recovery solutions (e.g., multi-level caching, fallback data, traffic switching) to enhance system robustness.
• Micro-Frontend Architecture Design & Implementation
  • Lead the integration of isomorphic rendering and micro-frontend technologies to achieve module decoupling and dynamic integration in multi-team collaboration.
• BFF (Backend for Frontend) Layer Construction
  • Build Node.js-based BFF middleware to aggregate heterogeneous backend services and optimize frontend-backend collaboration.
  • Abstract and encapsulate domain service layers for business needs based on backend APIs, designing highly cohesive and loosely coupled business modules.
• Engineering Quality & Automation
  • Promote code standards, automated testing (unit/integration/E2E), and code scanning toolchains to ensure delivery quality.
  • Design CI/CD pipeline optimizations to reduce build/deployment time, enabling capabilities like canary releases and one-click rollbacks.
• Visualization Building Services
  • Contribute to low-code/visual platform development by establishing standardized interface specifications to decouple frontend-backend collaboration and accelerate business iteration.
• Cloud Components & Version Management
  • Establish componentized development systems with dynamic version management solutions for multi-environment cloud components.

Job Requirements:

• Education: Bachelor's degree or higher in Computer Science, Software Engineering, or related fields.
• Technical Skills:
  • Deep expertise in at least one mainstream frontend framework (React/Vue/Angular).
  • Proficiency in Node.js ecosystems (Express/Koa/NestJS), with experience in high-concurrency handling, performance tuning, and memory leak troubleshooting.
  • Strong knowledge of relational/non-relational database design principles, including schema design, index optimization, and slow query analysis.
  • Hands-on SSR experience with frameworks like Next.js.
  • Familiarity with BFF development, RESTful/GraphQL API design, and gateway layer architecture.
  • Expertise in Jenkins/GitLab CI and containerized deployment (Docker/K8s).
  • Proven experience in complex system optimization (Lighthouse tuning, CDN acceleration, resource loading strategies).
• Experience: 5+ years in frontend development, including 3+ years leading Node.js projects in large-scale systems.
• Preferred Qualifications:
  • Experience designing/developing visualization/low-code platforms.
  • Background in e-commerce/financial systems with knowledge of distributed transactions (Saga/TCC) and eventual consistency solutions.
  • Full-stack development experience with backend languages (Java/Go/Python).
  • Cloud-native technology expertise (AWS/Aliyun) and Serverless implementation experience.
