Why this role exists

Medinex Workforce keeps a lot of information in databases: candidate records, client requirements, placement history, billing data. Every report and every tool depends on queries that pull the right rows quickly and correctly. A slow or wrong query means a recruiter waits or a manager sees the wrong number. As a Database Intern, you will write and improve those queries, and you will learn why one query returns in a second while another takes a minute.

Your day-to-day

- Write SQL queries using joins, subqueries, aggregations and window functions
- Create views and stored procedures for tasks the team repeats
- Design small, well-structured tables with proper keys and relationships
- Find slow queries and improve them using indexes and better query design
- Prepare clean data extracts for reporting and analytics teams
- Check data for duplicates, missing values and inconsistencies
- Share progress in daily check-ins and a weekly review

You are a good fit if
- You are solid in SQL basics (SELECT, JOIN, GROUP BY, HAVING, subqueries)
- You have worked with MySQL, PostgreSQL or SQL Server
- You understand primary keys, foreign keys and normalisation
- You think in a logical, structured way




- You double-check results before sharing them
- You have a laptop and a stable internet connection for full-time remote work

Nice to have, not required
- Knowledge of indexes and query execution plans
- Basic Excel or Python skills
- A SQL practice profile on HackerRank or LeetCode, or a database project

Who can apply
- Final-year students and recent graduates from B.Tech, B.E., BCA, B.Sc (CS/IT), MCA, B.Com or any stream with strong SQL skills
- Self-taught learners who can show their skills through practice projects or certificates
- Freshers are welcome, and prior work experience is not required

What you get
- Work on real databases and reporting requirements
- Regular guidance and feedback from experienced team members
- Query samples and database projects you can show in future interviews
- Internship completion certificate
- The freedom to work from your own city anywhere in India
