About the role
As a Node.js Developer, you will make an impact by building and maintaining scalable, secure, and high‑performance backend services that support modern web applications. You will be a valued member of a cross‑functional engineering team working in a modern, cloud‑native environment, collaborating closely with frontend, QA, product, and DevOps partners across a distributed team.

Our frontend applications are built in React, backend services are developed in Node.js, and both leverage modern JavaScript with Jest for unit testing. We follow a continuous integration and continuous deployment (CI/CD) model, ship in small, frequent increments, and deploy applications and services to the Azure Cloud.

7- 8+ years of IT.

In this role, you will:
Design, develop, test, and maintain backend services and REST/GraphQL APIs using Node.js frameworks such as Express, NestJS, or Fastify
Implement business logic, data validation, and error handling with a focus on performance, scalability, and reliability
Build and maintain integrations with third‑party services such as payments, messaging, identity, and analytics platforms
Work with SQL and/or NoSQL databases to design schemas, write efficient queries, and optimize performance
Collaborate closely with frontend engineers building React‑based web applications to define API contracts and resolve end‑to‑end issues
Write unit and integration tests using Jest and participate in code reviews to ensure quality and maintainability
Apply security best practices, including authentication, authorization, OWASP considerations, and secrets management
Contribute to CI/CD pipelines, feature flags, automated testing, vulnerability scanning, and deployment processes
Monitor, debug, and resolve production issues in Azure‑hosted environments
Create and maintain technical documentation for APIs, services, and operational runbooks
