About HackerKernel
HackerKernel is an IT software services company focused on building scalable web and mobile applications for clients across different industries. We are looking for an experienced Node.js Developer who can independently develop reliable backend systems and work closely with frontend, QA, and other technical teams.
Job Summary
We are looking for a Node.js Developer with 3–4 years of hands-on experience in backend development. The ideal candidate should have strong expertise in Node.js, REST API development, databases, authentication, debugging, and production-level application development.
Experience with TypeScript, Express.js/NestJS, Docker, Redis, cloud deployment, and API security will be an advantage. Current Node.js backend roles commonly emphasize REST APIs, database design, authentication, Git, Docker/cloud exposure, and production troubleshooting.
Key Responsibilities
Design, develop, and maintain scalable backend applications using Node.js.
Build and maintain secure, high-performance RESTful APIs for web and mobile applications.
Develop backend modules using Express.js and/or NestJS.
Work with MongoDB, MySQL, and/or PostgreSQL for database design and optimization.
Implement authentication and authorization using JWT, OAuth, or similar mechanisms.
Integrate third-party APIs, payment gateways, notification services, and external platforms.
Write clean, reusable, maintainable, and well-documented code.
Handle asynchronous programming, promises, callbacks, and event-driven architecture effectively.
Identify and resolve bugs, performance issues, and production-level problems.
Optimize API response time, database queries, and overall application performance.
Work with Git/GitHub for version control, branching, pull requests, and code reviews.
Collaborate with frontend developers, QA engineers, project managers, and other teams.
Participate in technical discussions, code reviews, and architecture decisions.
Support application deployment and troubleshooting in development, staging, and production environments.
Follow secure coding practices and maintain application reliability.
