The demand for scalable backend services is booming as companies shift to micro‑service architectures. A Node.js Developer role like this offers the chance to work with cutting‑edge JavaScript/TypeScript stacks and shape APIs that power modern applications. Joining Gurus Infotech gives you exposure to both document and relational databases, CI/CD pipelines, and a collaborative product team.

Job Summary

Gurus Infotech is seeking an experienced Node.js Backend Developer to design, build, and maintain RESTful APIs and micro‑services using Node.js, TypeScript, and Express.js. The role involves close collaboration with product managers, architects, and quality engineers while enforcing engineering best practices such as unit testing, TDD, and performance testing. Candidates must be comfortable with both document (CouchDB) and relational (MSSQL) databases and have hands‑on experience with CI/CD pipelines (Jenkins) and Git.
