Job description

Job Title: Backend Developer | Entry Level | Fresher Internship (Node.js, Express, MongoDB)

Company: Medinex Workforce

Location: India

Workplace Type: Remote

Employment Type: Full-time internship

Duration: 1 to 3 months

Stipend: Up to INR 15,000 per month

About the internship

Candidates never see the logic behind Medinex Workforce's tools, but they feel it the moment it fails: a login that does not work, a form that loses their details, a status page that shows the wrong stage. This internship puts you on the team that builds the layer behind the screen. You will create APIs, work with databases and add the security checks that keep candidate and client data safe, and you will learn how professional backend teams design, test and maintain the services other tools depend on.

What you will do

• Build and maintain REST APIs using Node.js and Express
• Design collections and write queries in MongoDB, and work with SQL databases where needed
• Add user login, token-based authentication and role-based access control
• Validate incoming data and return clear error responses so the system fails gracefully
• Test endpoints with Postman and write unit tests for your code
• Debug server-side issues and improve the reliability of existing services
• Use Git and GitHub for version control and walk through your work in code reviews
• Share progress in daily check-ins and a weekly review

What we are looking for

• Understanding of how HTTP, REST APIs and JSON work
• Basic knowledge of a database such as MongoDB, MySQL or PostgreSQL
• Careful, logical coding habits and patience when debugging
• A laptop and stable internet connection for full-time remote work

Nice to have

• Familiarity with JWT, Docker or cloud deployment
• Experience with Git and GitHub
• A GitHub profile or an API project you built

Who can apply

• Final-year students and recent graduates from B.Tech, B.E., BCA, B.Sc (CS/IT), MCA, diploma programs or related streams
• Self-taught developers who can show a project or certificate
• Freshers are welcome, and prior experience is not required
• You must be available full-time for the internship period

What you will gain

• Experience of designing and building real backend services
• Code reviews and guidance from experienced developers
• API projects and code samples you can show in future interviews
• The freedom to work from your own city anywhere in India

Full-time, Monday to Saturday or as assigned by your reporting manager, with daily check-ins and a weekly review.
