There's a Junior Data Warehouse Developer internship open in Andheri East, Mumbai, on-site, paying up to ₹15,000 a month. It sits in the Data Engineering & BI space, requires no prior professional experience, and is built for someone who's comfortable enough with SQL to want to get better at it using real company data rather than sample datasets. This is one of the data warehouse developer internships in Mumbai, specifically aimed at students and recent graduates rather than experienced hires.
Picture a regional sales report that used to take someone half a day to piece together by hand every Monday morning. Part of what this internship is about is helping to ensure that the report exists as a dashboard that refreshes on its own, with the underlying data pulled, cleaned, and shaped correctly before anyone downstream ever opens it. That's the core of business intelligence work: less glamorous than it sounds from the outside, and genuinely useful when it's done right. Most of the actual time goes into the unglamorous middle step, checking why a number in a report doesn't match what a stakeholder expected and tracing it back through the pipeline until the mismatch makes sense.
- Transform raw, messy data into structured reports that stakeholders can actually read
- Build and maintain dashboards for business teams who rely on them daily
- Keep existing reporting workflows running and fix them when something breaks
- Optimize slow queries so reports load faster instead of timing out
Who this is for
A bachelor's degree, either completed or in progress, in computer science, information technology, or something closely related is expected here. Comfort with SQL matters more than any specific certification. If someone has written queries for a college project, a personal side project, or a previous internship, that counts. There's no professional experience requirement for this opening, since it's designed as a first real job rather than a next step after one.
Learning curve expectations are realistic. Nobody walks in already fluent in the company's specific data model, and the first couple of weeks are mostly spent understanding how existing tables relate to each other before touching anything that feeds a live dashboard. What matters more than prior polish is a willingness to ask why a table is structured the way it is, rather than just copying a query pattern that happened to work once.
These are the skills that actually get used day to day:
- SQL, comfortably enough to write and debug queries without hand-holding
- A working understanding of data warehousing concepts
- Exposure to at least one ETL tool
- Familiarity with dimensional modeling
None of the following are required, but they'll make the first few weeks easier, and they're worth mentioning on an application if a candidate has them: some prior use of a BI tool like Power BI or Tableau, basic Python for scripting around data pulls, and any familiarity with Git for version control. Someone who's already dabbled in a cloud data warehouse like Snowflake or BigQuery, even briefly, will pick up the internal tooling faster, though that's genuinely a bonus rather than an expectation for an entry-level opening.
Pay and what comes with it
The internship pays up to ₹15,000 a month, which is a reasonable stipend for a data warehouse developer role in Mumbai given that this is explicitly an entry point rather than a full-time hire. It's worth being upfront that a stipend at this level generally works best for someone living at home or splitting rent with roommates in the city, rather than covering the cost of an independent Mumbai apartment on its own. Interns here typically get:
- A monthly stipend
- Direct mentorship from senior team members on the BI team
- A certificate of completion at the end of the internship
- On-site cafeteria access
- Cab or commute support
Strong performers are often considered for a full-time offer once the internship wraps up, though that isn't guaranteed and depends on how the team's hiring needs look at the time.
Working out of Andheri East
This role is based on-site in Andheri East, a well-connected part of Mumbai for anyone commuting by train or road, and it places interns in the same room as the BI team rather than looping them in via chat. Naukri Mitra regularly runs data engineering and BI internships in this same part of the city, so students weighing a few offers at once will likely see some overlap in what's available nearby. Sitting a few desks away from the people whose reports show up in actual leadership meetings makes it easier to see what "good enough to ship" really looks like, faster than a self-paced course tends to get someone there.
Interns are paired with a mentor from day one rather than handed a stack of documentation and left to figure things out. Questions are expected, and asking one early is treated as a better move than quietly guessing and fixing it later.
Applying
To apply, submit a resume along with a short note on any SQL or data project work done so far, even something small like a class assignment or a personal dashboard built for fun. Students currently enrolled in their final year are welcome to apply alongside recent graduates. Shortlisted candidates will be asked to complete a short SQL exercise before the interview, so it helps to be reasonably warmed up on writing queries rather than just reading about them. The exercise itself isn't designed to trip anyone up; it mostly checks whether a candidate can read an unfamiliar table structure and extract the right numbers from it under a bit of time pressure, which is close to what the actual internship asks for on day one.
The interview after that runs short, usually under 30 minutes, and covers the SQL exercise plus a few questions about how a candidate has approached messy or incomplete data in the past, coursework included. There isn't a separate coding round beyond the SQL portion. Offers typically go out within a week or two of the final interview, and the internship itself follows a schedule that aligns with a standard semester break for anyone still in college.
