Job Description

We are seeking an experienced Software Developer specializing in GraphQL and Node.js to design, develop, and optimize scalable APIs and microservices. The ideal candidate will have strong expertise in GraphQL schema design, resolver optimization, API security, and backend integration.

Key Responsibilities

  • Design, develop, and maintain GraphQL APIs, including schemas, queries, mutations, and subscriptions.
  • Implement schema federation or stitching using Apollo Federation or similar technologies.
  • Optimize GraphQL performance using DataLoader, batching, caching, and query complexity controls to prevent N+1 issues.
  • Develop backend services and microservices using Node.js, TypeScript/JavaScript, and frameworks such as Express, NestJS, Fastify, or Apollo Server.
  • Integrate relational and NoSQL databases, including PostgreSQL, MySQL, MongoDB, and Redis.
  • Integrate REST APIs, gRPC services, and third-party platforms into GraphQL data layers.
  • Implement API security, including authentication, authorization, RBAC, rate limiting, and query depth restrictions.
  • Troubleshoot and optimize API latency, throughput, scalability, and memory usage.
  • Develop automated unit, integration, and end-to-end tests using Jest, Mocha, or Supertest.
  • Collaborate with frontend teams to define API contracts and support web and mobile applications.
  • Participate in code reviews, architecture discussions, and CI/CD improvements.

Required Skills

  • Strong hands-on experience with GraphQL API development and Node.js.
  • Proficiency in TypeScript/JavaScript and backend frameworks.
  • Experience with GraphQL schemas, resolvers, queries, mutations, subscriptions, and API integration.
  • Knowledge of Apollo Server, Apollo Federation, DataLoader, and caching strategies.
  • Experience with SQL/NoSQL databases and REST/gRPC integrations.
  • Understanding of API security, performance optimization, automated testing, and microservices architecture.
  • Familiarity with Git, CI/CD pipelines, and Agile development practices.

Preferred Skills

  • Experience integrating GraphQL with React, iOS, Android, or other frontend applications.
  • Knowledge of Redis and CDN/edge caching.
  • Experience with production-scale API monitoring, debugging, and performance tuning.
