About the role
Contract type: full-time
Start date: Upon Agreement
As a BI Data Analyst, you’d be part of the team building out reporting for a fast-moving e-commerce business operating across 21 European markets – working with our data warehouse to turn business questions into reports people actually rely on, with a strong focus on the financial side of the business.
What you will do:
•
You’d design and build Power BI reports – from data model to DAX logic to the final visual – working closely with our database and BI specialists along the way.
•
You’d work directly with Finance and other business stakeholders, helping them shape a rough idea into a report that actually answers their question – margins, costs and P&L included.
•
You’d get comfortable spotting trends, inconsistencies and manual work worth automating, and suggest where reporting could do more.
•
You’d take care of data quality and validation on the reports you build, so people can trust the numbers without double-checking them.
•
You’d help present findings in business reviews, explaining what the data shows – and what it means financially – in a way that lands with people who don’t work with Power BI day to day.
•
You’d grow into a go-to person for Power BI, DAX and Power Query on the team, with support from more senior colleagues along the way.
What we are looking for:
•
Strong hands-on experience with Power BI, including confident use of DAX, data modelling and Power Query.
•
Good SQL skills and the confidence to analyse large datasets, plus solid working knowledge of Excel.
•
A strong analytical and problem-solving mindset.
•
Experience working directly with business stakeholders.
•
Ability to translate business questions into reporting solutions.
•
High attention to data quality and validation.
•
Ability to explain analytical findings clearly to non-technical audiences.
•
A finance background, with an understanding of P&L, margins and cost structures.
•
Fluent English and Slovak, since you’ll be working closely with both local and international colleagues.
