MERN Developer

About the Role

We’re looking for a hands-on JavaScript Backend Engineer with strong MERN experience to build scalable, secure, and high‑performance services and APIs. You’ll design and develop Node.js microservices on Azure, integrate GraphQL, work with MongoDB/MySQL data stores, and collaborate with frontend engineers using React.js to deliver end‑to‑end features.

Key Responsibilities

• Design, build, and maintain Node.js microservices (REST/GraphQL) hosted on Azure (App Services/AKS/Functions).
• Develop GraphQL schemas, resolvers, and data loaders; optimize query performance and caching.
• Model, query, and tune databases: MongoDB (primary) and MySQL (relational use‑cases).
• Implement CI/CD pipelines (Azure DevOps/GitHub Actions) and follow IaC best practices (Bicep/ARM/Terraform – nice to have).
• Ensure service reliability: logging, monitoring, alerts, and distributed tracing.
• Apply secure coding practices, secrets management, and role‑based access.
• Collaborate with React.js frontend to define contracts and deliver cohesive product experiences.
• Write high‑quality, well‑tested code (Jest/Mocha), perform code reviews, and contribute to technical documentation.

Must‑Have Skills

• Node.js/TypeScript (or strong ES6+) for backend services and API design.
• GraphQL (Apollo/Helix) — schema-first design, federation basics, data loaders.
• MongoDB — schema design, aggregation, indexes; MySQL — joins, transactions, migrations.
• Azure — microservices deployment (App Service/AKS/Functions), API Management, Storage, Key Vault.
• React.js fundamentals for integration and API contract alignment.
• Git, branching strategies, code reviews, and CI/CD exposure.
• Performance profiling, debugging, and observability (Application Insights/Prometheus/Grafana).

Good to Have

• Containerization with Docker and orchestration with Kubernetes (AKS).
• Event‑driven patterns (Service Bus/Event Grid/Kafka), caching (Redis), and rate limiting.
• Testing: contract/e2e tests (Playwright/Cypress), Pact, and API mocking.
• Security: OAuth2/OIDC/JWT, OWASP, vulnerability scanning (Snyk/Dependabot).
• Experience with Domain‑Driven Design, Clean Architecture, or Hexagonal.
