Job Summary

Were a data and analytics team that builds reporting products for enterprise clients. We need a Power BI developer who can pick up a complex existing model figure out whats wrong with it and fix it then keep building on top of it.

This isnt a role where youll be handed clean requirements and told what to build. Youll be given a problem access to the data and expected to drive to a solution. If that sounds like your normal working style keep reading.

Start - As soon as possible
Stack - Cloud data warehouse Power BI Import Mode
Model size - Large enterprise model 80 tables 200 DAX measures
Shift Time - IST 3pm to 12am

Day to day the work looks like this:

Taking ownership of reports that are already in production diagnosing performance issues fixing broken measures and extending them with new pages and features
Writing DAX from scratch. Not adjusting templates or copying patterns from documentation actually understanding what the engine is doing and writing accordingly
Working directly with stakeholders who dont speak Power BI. Youll need to ask the right questions to understand what they actually need not just what theyre asking for
Keeping the data model clean removing dead weight managing relationships and making sure things dont fall apart when the data changes upstream
Collaborating with data engineers when a problem traces back to the source you dont need to be a SQL expert but you need to be able to have a technical conversation

Qualifications :

Hard requirements dont apply if you cant tick all of these:

5 years of Power BI development on real enterprise models not demos or training datasets
DAX at an expert level. CALCULATE SUMX TREATAS FILTER GROUPBY time intelligence you know when to use each one and why and you can debug your own work
You know how to use DAX Studio not just open it but actually use Server Timings to figure out where a slow query is spending its time
Tabular Editor is part of your normal workflow not something you Google when someone mentions it
Power Query (M) you can write and fix transformation steps without clicking through the GUI
You understand the data model underneath the visuals: relationship direction cardinality filter propagation and what breaks when you get these wrong
SQL enough to read a query write a basic one and hold a conversation with an engineer about whats happening in the database

We expect hands-on familiarity with these. Well ask about them in the interview:

DAX Studio - Query diagnosis Server Timings VertiPaq Analyzer the main tool for any serious performance work
Tabular Editor 2 or 3 - Best Practice Analyzer batch measure editing model cleanup
Performance Analyzer - Identifying which visuals and queries are slow built into Power BI Desktop
Measure Killer - Finding and removing unused measures and columns from the model
Bravo for Power BI - DAX formatting and model documentation
ALM Toolkit - Comparing and deploying model schema changes across environments
Optimize Ribbon - Pausing visuals while editing managing aggregations

Good to have :

Background in real estate energy or sustainability data we work in this space so familiarity helps
Experience with Power BI Service workspaces refresh schedules deployment pipelines RLS
Incremental refresh and large fact table strategies

Additional Information :

Probably not a fit if...

You need requirements fully written before you can start
You fix performance by cutting data not by fixing the DAX
You use AI tools to write your measures
Your models work but nobody else can maintain them

Likely a strong fit if...

Youre comfortable working backwards from a business problem
Your first step with a slow report is Performance Analyzer and DAX Studio
You write DAX from memory and can explain every line
You write clean commented code like someone else will need to read it

Send us two things:

Your CV focus on the Power BI projects not the job titles. Tell us the model size what the data looked like and what you specifically built or fixed
One real example of a performance problem you diagnosed and solved in Power BI. Show the before and after and explain what was actually wrong. A paragraph is fine we dont need a case study

We read every application. If you dont include the performance example well assume you dont have one.
